Holiday Season Gifts - RC Cars(Radio-Controlled) are Less Expensive

What is an RC car?

RC stands for radio-controlled. An RC car or truck comes in either toy or hobby grade. Let's take a look at the difference:

Toy grade RC cars are less expensive and can be found at most electronics stores.  But if you're serious about making RC cars one of your hobbies, they aren't your best bet. If you're really interested in RC cars, you'll want the hobby grade car or truck. There are lots of advantages to the hobby grade car. For instance, they have tons of available spare parts and upgrades. For a lot of people, they don't just love racing their RC cars--they also love building and fixing it up.

Now that you know the basics of RC cars, it's time to decide what kind of car or truck you want to buy.


RC Cars - The #1 RC Hobby

The kind of all RC Hobbies is the RC Car. Radio controlled cars only move in 2 dimensions (it shouldn't be flying under normal circumstances), they are inexpensive, they can be driven by anyone old enough to ride a bike, and they are easy to repair. The real question comes down to what you expect from your rc car.

Want speed? Some of these cars can move upwards of 70+ mph! Obviously this isn't for an eight year old to play with unless they are extremely responsible and an amazing driver. Certainly it shouldn't be their first car. You can expect to pay around $300 for this type of setup.
Traxxas RTR 1/10 Rustler VXL 2.4GHz with 7 Cell Battery and Charger     Traxxas RTR 1/10 Rustler VXL 2.4GHz with 7 Cell Battery and Charger

The great thing about these Traxxas rc cars are that if a part breaks you're not out $200 or $300.  Traxxas makes a full line of replacement parts for those unfortunate accidents.  Honestly that's why I recommend these cars.  They take a lickin' and keep on tickin'!  Do yourself a favor and spend a few extra bucks and have these cars for the next couple years.  Its a great RC hobby to jump into.

Wanna off-road? Some of the rc trucks have monster tires and can rip through some pretty rough terrain. You can build an obstacle coarse are race your friends. Lots of fun can be hand with this off-road rc cars. Here are a couple products in the $200 price range.
Traxxas RTR 1/10 Stampede with Water Proof XL-5 and 7 Cell Battery with Charger Traxxas RTR 1/10 Stampede with Water Proof XL-5 and 7 Cell Battery with Charger

Racing RC car

Ah, finally, the opportunity to seize and conquer the open road. Well, on a smaller scale. But it certainly can't be denied that one of the appeals of the RC car is that it allows you to go a little crazy--maybe a little too fast, maybe be a little (okay a lot) more dangerous than you (hopefully) are when driving an actual car.

Types of Racing RC car

Oval Track - This is your standard way of racing RC cars--not to say it isn't awesome, because it's definitely a lot of fun. Again, check with your local hobby shop or your RC Club for good oval tracks in your area.

Off-Road - A lot of people enjoy the freedom and fun of off-road RC driving. And it's true--you can go pretty wild with off-road racing.

Drag Racing - If pure speed is your thing and you don't care so much about jumps and stunts, drag racing is for you. Drag racing involves a 1/10 replica of a drag strip. You can buy RC drag cars that will rip across the strip in little more than a second. As you might imagine, they're some of the fastest RC cars out there.

Competitions RC car

If you've practiced racing your car and want to amp up your hobby, then definitely enter a competition. They're a lot of fun and a great way to connect with other RC racers. If you haven't already, join an RC Club and you'll know where to compete.

Advantage of push-pull

I have been thinking what are the advantages and disadvantages of push-pull configuration. Everyone knows that push-pull has both disadvantages of pusher and tractor configuration but also implements a simple to control center line thrust operation for a critical single engine situation. However, there is more than that to it.

If you think one-of-a-kind aircraft, e.g. what Burt Rutan used to do during the early years. You want to build a twin on a shoestring budget. Then you realize that you have to buy two of everything. What if you have two engines already hanging around but they are not exactly the same make, model and horse power.

In case of center line thrust, no problem. Nothing requires the two engines to be the same. Not even weight and balance. Burt Rutan's Voyager is an example. You can find that the front engine is different from the rear engine.

It might not be because of the reason described above, but if you are into auto conversions and designing a twin, how you plan to get two identical engines for not much cost at all (from totalled cars for example). Might prove to be a challenge, especially in a country like Finland where the population and the availability of engines might be poor. With center line thrust you can use different engines in the front and rear.

By the way: Merry Christmas and Happy New Year!

Best Holiday Season Gift for All Aviation Enthusiasts - Ding Duck

  The Best Christmas Gift you will Present to yourself or to your dear one's this season is
this book that will delight anyone with an interest in Aviation: Full Power Ding Duck

 
Poor Ding! He’s a duck who just wants to fly, but can’t seem to get it. All aviators can relate to Ding’s misadventures… we’ve all made mistakes, done it tough, had our pitfalls.
What Ding teaches us is: never give up. Should we feel sorry for Ding? I rather feel sorry for his flying instructor!
Ding Duck is just one character in Gary Clark’s “Swamp” cartoon world. In “Full Power Ding Duck” Gary as brought us a collection of over 250 cartoon strips featuring the aviation world and a bird-brained hazard.

Buy it for yourself, or as a present for the aviator in your life. You will love it!
From the preface:
For someone who can’t fly it’s amazing the places Ding Duck finds himself in the Aviation world. He’s a perpetual student having logged over 5,987 flying lessons without once ever taking off. Yet you can find him on countless Flying School walls. His every attempt to fly ends in a mishap or disaster but he has featured in official Air Safety campaigns. He fails all his flight theory exams but he appears in textbooks.

His determination to get airborne despite the struggles, pitfalls and setbacks is what every aviator can relate to. Ding Duck is a reflection of the realities of the irony, pain and love of aviation, which can cause endless frustration to most pilots; yet despite all this we, like Ding, keep coming back for more.

Visit
To learn more about Ding and his friends, and to buy this book, visit Gary at his fabulous website, www.swamp.com.au. You can also view his cartoon archive and register for a free Swamp cartoon to be delivered to your email inbox every day.

Nextcraft

I found a quite interesting site:
http://www.nextcraft.com/
There was for example a 1/3 scale Berkut/Long-Ez project. 1/3 scale RC-model is said to be minimum sufficient for modeling the full scale aircraft, so I find this example quite educational. As can be seen though, the airfoils are different than on the full size plane. This is necessary because of the very low Re of the model. It does not thus model it very accurately, so there might be still surprises on the full scale version when scaling up, but I think it would still be good to do 1/3 models of new aircraft designs.

The direct link to the 1/3 scale Berkut can be found here: http://www.nextcraft.com/berkut01.html

GA aircraft comparison chart

Here is a interesting specification chart which illustrates the differences between different aircraft types:
http://www.flypas.com/images/DA40_comparison_feb_2020_rev_2_022408.pdf

I knew that information already, but this is a chart you can look at if you don't happen to know which is the difference between Diamond DA40, Cessna C182, Cirrus SR20 and Piper Archer. Needless to mention (but I mention anyway), the models utilizing composite high aspect ratio wings with super-accurate surface and laminar flow airfoils are the winners on this chart, namely the Diamond DA40 and Cirrus SR20. On this chart, the DA40 wins also SR20. Indeed, the DA40 is pretty good compromise, but the SR20 is not so bad compromise either. It has for example larger cockpit for larger people. However, bigger size does not come without a penalty and it is evident in the specs, SR20 takes more power to go as fast as the DA40 with 20 hp smaller engine (75% power = 135 hp whereas on Cirrus 75% power = 150 hp). The biggest losers on the chart, obviously, are made of metal (with protruding pop-rivets), and have turbulent flow over the low aspect ratio wing.

The same page also has a comparison made between trainer type aircrafts:
http://www.flypas.com/images/comare_da20.pdf

The comparison chart contains Diamond DA20-C1 Eclipse, Cessna C172, Piper Warrior and Cirrus SRV.
This is not completely fair because some of the planes are 4 seaters and some two seaters, but isn't still too hard to see the difference between the laminar flow planes compared to turbulent flow planes. Both Diamond DA20-C1 Eclipse and Cirrus SRV use laminar flow airfoil, slotted flaps and a high aspect ratio wing. Both are made of composite materials. I have flown myself the Diamond DA20-C1 Eclipse and the SR20 (the IFR version though, but it is no different from the SRV other than in terms of certification and equipment), both are really nice aircraft to fly and they perform pretty well when comparing to the competition. Of these, the DA20 is most pleasant although quite a bit slower in the reality than the Cirrus.

The page also has a performance vs. altitude chart for three aircraft types - 2 Mooney and Cirrus SR22 (normally aspirated version). From this chart, the effect of the turbo is quite evident on the turbo-version of the Mooney. At high altitudes it is the fastest of the compared aircraft. The comparison would get tougher if the SR22 was the turbo-model which cruises well over 200 kts at high altitude.

http://www.flypas.com/images/comparison1.pdf

The comparison chart has some things which I am not in full agreement with. For example the front hinged canopy superiority. It gives good view from the cockpit yes, but it is stating that it makes it easy to get into the cockpit. That is very far from the truth. It is a lot easier to climb to a Cirrus through the door than to a Diamond. Getting into the Diamond is like getting to a sports car. It is not that difficult and I would not consider it personally a problem, but saying that it is superior in easiness compared to the side doors of Cirrus, that is bullsh*t. Cirrus is a lot bigger and easier to get into. Diamond excels elsewhere than on this. And there are other things too on this list, so please have your filter set to on when reading it. In a sense, the comparison chart in the plastic planes is better.

Here is the comparison from plastic airplanes:
http://philip.greenspun.com/flying/plastic-airplanes

And here is a Cirrus SR20 review:
http://philip.greenspun.com/flying/cirrus-sr20

And here is a Diamond DA40 review:
http://philip.greenspun.com/flying/diamond-da40

Low pitching moment NLF airfoil with low sensitivity to bugs and dirt

Here is the Honda's tech paper about the SHM-1 airfoil (which was designed for the Honda-Jet). The airfoil includes features which are not important on low speed low Reynolds number flight but it also has features which makes it ideal for lower speed concepts:

http://hondajet.honda.com/pdf/tech_papers/Journal_of_Aircraft_Vol40_No4_P609_P615_SHM_1_NLF.pdf

SHM-1 could be a good starting point for an airfoil for GA-use. The Re area for the SHM-1 is a lot higher than needed by GA, so it may not be directly applicable, but the ideology in the SHM-1 seems just what would be needed for also high speed high efficiency, long endurance GA aircraft, which in addition to having low drag and high Clmax also exhibits good behavior.

Interesting data about ultralight aircraft

I found interesting paper which tells some details about some ultralight aircraft, the better, even about the TL-96 Star we previously owned. I find it quite interesting.
http://ctn.cvut.cz/ap/download.php?id=77

SpaceShipTwo unveiled

Here is a great article with pictures and video:
http://news.bbc.co.uk/2/hi/science/nature/8400353.stm

Awesomely pretty machine. I would like to fly that thing (as a pilot rather than passenger).

Boundary layer suction

I have stated here previously that the boundary layer suction maybe requires jet engine for having enough power to be wasted for the suction. However, a knowledgeable friend just sent me couple of (more) links as he has used to do now for quite some time. (Thanks by the way). Interestingly enough on this ppt: www.aoe.vt.edu/~mason/Mason_f/LaminarFlowS04.ppt on page 17 it has been stated that the example case of Piper Super Cub only required 2.0 hp for suction. Another example was Cessna L-19 with 17 hp used for suction.

This is very interesting since taking 2-17 hp out of e.g. 200 total hp (=2 x Rotax 914) is quite doable. With smaller engine power as the previously discussed 2 x HKS700E, the available excess horse power for suction would be obviously smaller and taking 7 hp out of the available thrust would be unwelcome whereas taking only 2 hp out of it would be clearly still within limits of potentially feasible and that benefit outweights the loss.

The achieved Clmax increase with boundary layer suction is significant. If on the Cessna example the Clmax increased from 2.5 to 5.0, that makes a whole lot of difference in wing sizing and in turn this affects drag and efficiency significantly.

The downside is that if the wing sizing is done with the expectation of Clmax of 5.0, and then because of mechanical failure, the suction is not available, the stall speed in such emergency would be high. Also potential failure modes are that the suction disappears on final approach or shortly after takeoff.

How to mitigate this potential problem? The suction mechanism would need to be very reliable and most likely it should be doubled. In other words, in twin engine aircraft, either engine should alone be able to supply enough suction so that in case of engine failure of one suction pump failure, the aircraft would not crash but could still safely land on the airport (with the remaining engine and remaining suction pump).

Another way to mitigate the problem could be to not count on the achieved Clmax but only take the benefit of the drag reduction caused by the suction. There comes the question then of the justification of the added complexity. One of the unknown issue to me is that how water ingesting through the perforated skin would be dealt with - it would be pretty severe condition to have whole suction slot full of water. In addition to the suction not functioning properly, the wing would weight significantly more.

What the complexity adds to the manufacturing cost? For small commercial general aviation aircraft (which is targeted to masses and which does not try to achieve anything special but be good all-arounder) it could add more than is justified for the benefits gained from market - simplicity and low cost manufacturing drive these rather than the last decimals in the efficiency. However, for experimental prototype aircraft which is built on basis that price of a work hour is not counted, at least then this might be a feasible idea to incorporate. This would require more investigation, and it could depend quite much on the aircraft configuration, how much gains this could add and what kind of tradeoffs there are to be expected in turn.

Amy Johnson the First Woman to fly solo from England to Australia

1930: Amy Johnson - Queen of the Skies

Born in England, Amy Johnson was one of the most courageous pilots of her time. She set many records, including being the first woman to fly solo from England to Australia, in 1930.

Amy set many other records, both by herself and with her aviator husband Jim Mollison.

Here is some movie footage about Amy…

Jet Engine is invented in 1937 by Frank Whittle.

The Jet Engine

The jet engine is one of the coolest, most amazing inventions ever designed. It is reliable, converts fuel into huge amounts of thrust, and can be REALLY loud.

It is the jet engine which allows HIGH SPEED, HIGH ALTITUDE flight, getting you to your destination within hours rather than days.

The jet engine take air in the front, burns some fuel,
and sends air and exhaust out the back at high speed. The engine
actually PUSHES this air out the back, resulting in the engine
getting a push forwards.

It sounds simple, but it did not get invented until 1937, by a
bloke called Frank Whittle.

They look pretty cool, don't they?

But 76500 ft looks even cooler:



http://www.flickr.com/photos/nebarnix/sets/72157607393699828/

Interestingly though, 42000 ft still looks pretty amazing:

Will it blend?



Seems like, yes it did :)





Created with the latest iRhino alpha.

Changes:
* Placeholder engine nacelles added.
* Rudder added

I was reading today the book "Fluid dynamic drag" a bit and got kind of inspired: canopies and wind shield discontinuity contributes very much to the drag coefficient of the fuselage. Not only the laminar nose seems important, but all kinds of places where something ends and something else continues are sources of waste of engery.

So if the plane is completely faired with no discontinuity of any kind, theoretically the drag coefficient should be very low.
In this picture, the engine nacelle placeholders are just placeholders, because they are not yet accurate airfoil, and it has not been taken into account that in Rotax engines the propeller shaft is not in the middle of the engine, but almost on the top of the engine, this creates a fairing that has the lower side turned up a bit and is therefore not completely symmetrical.

The engine nacelles may need to be moved outwards, otherwise there is not enough clearance between the fuselage and the propeller arc.

I was also reading one day some NASA tech paper about wing tip mounted propellers. I have not drawn such things to this picture, but I may add it later - small brushless DC motor on each wing tip lowers the induced drag quite a bit according to the tech paper (although on high aspect ratio wing the effect is not that radical as on with a low aspect ratio wing that would otherwise be poor).

Potential issues for placing engine nacelles on wings (which seems pretty necessary for a twin, after all, may be the least bad compromise) and blending are the followings:
* the wings take a lot room to build (because they are very long)
* making the mold is difficult, because it has to be done from CNC cut pieces and glued together
* moving the center section to airport or transporting it in a container may be challenging, because if the area up to engine nacelles is continuous part of the center section and not separatable, it means that this is basically wider than the width of the container, shipping the plane to another continent might be a challenge (it seems that it would need to be flown like the design point has been set)

Three turbos in Subaru EJ22

Hey watch this out:
http://www.youtube.com/watch?v=bU2elPTJyqA

Pretty interesting system built around the Subaru.

HALE

I have been thinking one idea for better utilizing the HALE concept (HALE = high altitude, long endurance).

Usually nobody flies higher than about 40000 ft. If you look out from a commercial passenger aircraft's window, what you see is blue. You can don't even see clouds very well since you are too high to see them closely and you are too low to see the curvature of the Earth and blackness of space. And the publicly available photography from that altitude is very limited, you don't really get to see even virtually how it looks like up there.

There are some interesting videos about balloon flights to high altitude in Youtube. The balloons go to about 80-100 kilofeets. According to videos, that looks already almost like space. Couple of examples:

Long Trail School High Altitude Balloon at Youtube

Nevada BalloonSat at Youtube

The view is so amazing that I feel it odd that nobody has started to carry people to near space experience with high altitude aircraft. Someone offers MIG-flights, but that is just a ballistic jump there from supersonic flight. Aircraft that can loiter in that altitude would give a whole different experience, it could stay there longer than just minutes.

That kind of aircraft would be impossible someone might say? Not so black and white. There are couple of HALE UAVs around which can go this high. And if you for example look Scaled Composites Proteus which can reach 70000 ft, if you'd replace the telecommunications load from the center section with space grade pressurized passenger cabin, the plane could lift several people at one time to the abovementioned altitude.

According to material I have been seeing from high altitude balloons, it seems like the sky is starting to look like space from about 60000 ft upwards. You need afterburning jet engines to go that high? Not necessarily. Look at for example Burt Rutan's UAV that had twin turbocharged modified Rotax 914 (with fuel injection). It was designed to have positive climb rate at 63000 ft. Seems feasible with piston engines in other words. The company that did the Rotax-conversion for the Scaled Composites UAV, have done triple turbocharged and twin turbocharged versions of the Rotax. The triple turbocharged Rotax is usable to over 80 kft, however, the installation looks really complicated (and the biggest turbo is so huge that must be from a truck).

Tecnam P2006T

Here is a design paper about Tecnam P2006T. I find it quite interesting.
www.aidaa.it/3-2020/P2006_corr.pdf

Interesting detail with the used Rotax 912S is that it provides actually better thrust at takeoff and climb than same horse power with a Lycoming engine (because the engine nacelle has smaller frontal area and the propeller rotation speed is lower).

Today is American ThanksGiving Day - Black Friday Shopping Tips

The Ultimate Tips To Make Shopping During The Black Friday

Today is American thanksgiving so I wanted to take a moment to
share with you some of the most important realizations in my life regarding
this idea of being thankful...

In our quest for "more" we often forget how great and precious what
we already have is. And what's the point of getting more if you can't get
enjoyment out of what you have? That's a pretty strong demotivator if you
ask me...

We often spend so much time in the unhealthy zone of envy or lack.
What we don't have and would like to have. What other's have that we don't...
And we often tend to measure ourselves so cruelly:

When we set goals, we look to the ideal we want to reach. And all too often,
we make the terrible mistake of judging our accomplishments thus far
against that ideal.

Not only can we never win in that scenario, but we are doomed to
come up short 100% of the time. Not much of a life...

The trick is to measure backwards. Look where you came from and
where you are now, that will always paint a more realistic and pleasant
picture.

What if you want to increase your happiness and gratitude, starting
right now?

It's easy!
     So, is black Friday really the best time to buy?

Black Friday is the day following Thanksgiving Day in the United States. It have become a the day where companies make big money. Retailers like Best Buy sell a lot.

I know a lot of people  enjoy holiday shopping due the discount and coupons that can be found during this period. Frankly, I’m not fond as people spend their money during the holiday shopping season. Anyway, despite I’m not a holiday shopper, it doesn’t means you don’t like buy on Black Friday.

So, if you’re going to shop today, I want to share some useful tips that will help you make your holiday shopping less stressful, easier, and more successful.
Best Tips To Shop On Black Friday

1. Make a plan - Without a plan, Black Friday becomes a hectic day. I’ll suggest to don’t go to shop without a list in hand. This is the best way to have all your offers in the same place, and make you take a decision quickly.

2. Shop from home – Today, many of discount offered by retailers on Black Friday are available online. Sites like BlackFriday.info, Black-friday.net, and Blackfriday.org are the perfect place to find which stores have the best deal to your needs. Coupons.the3dtechnologies.com also provides blackfriday offers.

3. Get Social – Being most retailers have a Facebook(this is the page of Best Buy https://www.facebook.com/bestbuy) and Twitter account, I’ll suggest to join to their network. Often they provide coupons and discounts on some products and you could get some interesting deals.

4. Know when retailers are opening – Know the store hours is become important when it comes to grab the best deals. If you wait until the last minute and your order happens to arrive damaged, you don’t have time to send it back and replace it with something else.

5. Use credit card – Often buy with Credit Cards can give you more benefit then buy without it. Credit card that gets rewards let you rack up the point while you shop. Lowcards ranked the best retail rewards credit cards on the market.

Entrepreneurs of Aviation

Entrepreneurs and Aviation
The event, which by many is considered “the Oscars of Aviation” is all about recognizing and honoring individuals with great and significant contributions to the field of aviation.

Rather than just being a “star studded” event, many Hollywood and Aviation celebrities are passionate about aviation and attend this gathering to help pushing the message of keeping the dream of flight alive and to make it real to people that aviation is not just something for a few select individuals but plays an important role in today’s society. 

The current 70 people who are now part of the Living Legends of Aviation are people of remarkable accomplishments, in aviation. Members include entrepreneurs, innovators, industry leaders, record breakers, astronauts, pilots who are now celebrities and celebrities who have become pilots.

John Travolta, the Ambassador of Aviation is himself a Legend of Aviation and started flying at the age of 17. He presented the newest Inductee Mr M Laurent Beaudion, the CEO of Bombardier with his award. His accomplishments to bring aviation forward are nothing short of remarkable.

Sean Tucker, the award emcee, always has an enthusiasm for aviation that is contagious to anyone he gets in contact with. From a reliable source, and from what I have seen with my own eyes, he is probably the greatest aerobatics pilots currently flying at air shows – a true professional in his field.

Actors and Pilots Harrison Ford and Kurt Russell gave out several recognitions at the event. Harrison Ford has done a remarkable job to introduce people and our youth to flying and is a great proponent and spokesman for aviation.  Awards included the “Aviation Legacy Award” given to Pat Epps, Atlanta, Georgia. Captain “Sully” Sullenberger awarded Captain James Lovell, Apollo 13 Commander, the “Captain Cool Award”.

Delford M. Smith who founded Evergreen International Airlines was given the “Lifetime Aviation Entrepreneur of the Year Award” Clay Jones, the “Aviation Industry Leader of the Year” and Lynn Tilton, the first woman to achieve the “Aviation Entrepreneur of the Year” award. Frank Robinson, founder of Robinson Helicopters, was acknowledged for his role in creating what ended up becoming the most popular helicopter in the world.

Bob Hoover, a true Legend of Aviation in his own right presented the Freedom of Flight Award to his fellow aviator and congressman and national hero, Sam Johnson.

After the event many celebrities gathered on the 8th floor of the hotel, mingled with guests and and shared stories about aviation with those who attended.
