Default Can this design fly?

Hi all,

I remember playing this video game at a gas stop a while back and they had some wicked looking propeller fighters looking very close to jets. But here is one airplane design i had based off of one of the fighter planes and i was wondering if it was able to fly or not. here are the pics if anyone has any suggestions please post.

Thanks.

Looks like it would. Follow the simple laws of aerodynamics and it'll fly.

Have you read Andy Lenon's R/C Model Aircraft Design?

Default Heck yes it'll fly!

GreenAce92::Heck yes it'll fly! great look'in lay-out you got there!! remember one can fly a lawn-chair with enough power, I like every thing about it, I may have to do a knock-off!! Are you do'in it in foam? your bub, stevecooper

Awww coool you did the Howard Hughes 2 engine plane the one that crahsed in the movie cool plane. Correct me if im wrong about the plane or which one it is but great job she looks nice. How well does she fly? Sure you can build one with your own design and changes. I have to buy some foam and get a good radio system i have to look around anyways so this project is not going anywhere right now for me but yeah sure if you want to build a model of this design go ahead. I would like to see someone else's version. Thanks for the encouragement.

Default sand-shape about any plane you want

GreenAce92::Heres some more, go buy some foam chuncker's an start from there, You can sand-shape about any plane you want an they fly GREAT! your stevecooper

Cool planes they look really nice. Now do you sand those by hand? I will have to do a micro scale of this design first strap a little engine and a tiny lipo battery and do a free flight model see how good she flies. I would like to make it a 4ch preferrably in the 40in wngspan area. I dont know about wheel setup i will probably run a triwheel or a taildragger dont know which one will look better.

Default Good Job

It will fly as long as you keep it at 5' or less scale wise, if you go up from there, the tail feathers don't need to be that large, but will work anyway, be it more responsive then what you are prepared for.

Given the proper power source, it will be fast, this is due to the swept back wings, yet with the chord and length of them, it's going to let you take it in for a slow landing. I'd pursue it, it looks like a keeper of a design.

Thanks i will build it once i get the right foam material and my Optic 6. I am going to probably build the body first then i will add the electronics later because i am going to use the first electronics for my GWS Beaver and the E-flite P47. What do you think would be a better type of landing gear for this plane a tri wheel or a tail dragger? Also how would i carve the cylinder fuselage out? Would i start with 4 long rectangular boxes and then cut out an outer curve for each one and then glue all for pieces together or is their an even more simple way?

Landing gear is based upon your skill level, a trike will be most stable at avoiding ground loops, but tail draggers are more forgiving upon landing in my book.

Along the cylinder, if you have a wire cutter, I found that mounting it in a bandsaw fashion, then mounting a bolt through the center of the stock will let it act as a lathe. If you don't have a wire cutter, I'd glue the fuse pieces together, making sure the glue is in the center section only, and sand it to shape, if the glue goes too far outwards, it will create an uneven density which may be difficult to evenly sand. You can fill the gaps with glue after you are happy with the shape.

Fred, how is the reading coming along btw?

Hey Steve...pretty clever planes, you are a genius, love the yogurt cups! I,ve used the cups that come with cough syrup for cowls on direct drive 280s. What is that glider called that you cut up for the Hughes spy plane...I chopped up one my son had and modified it. The wing is nice and fast with a little sanding but not sure who makes the glider. I would like to get some more.
Thanks Joe

So how would i go about shaping the body? Do i just cut C shapes into foam and line them up and then put ribs across or do i just make ribs then wrap sheets up around them im thinking of using fanfold foam for the bendability. How durable is that stuff? Can i cartwheel across the ground and plane would be in one piece still? Also aileron placement just put them close to the wingtips? I will probably do my first one with a landing gear from something but it will be stationary and if it proves to fly really well i will try doing retracts to make it look more scale. That i think would be hard though and i will have to research on it. Im hoping that my Optic 6 transmitter i am planning on buying can do alot of functions on it to attach cool little nifty things on my airplanes i will build.

Ace, you are thinking along smaller scale endurance wise due to the inertia. Once you get past aeroace scale and specs, this stuff becomes a new beast, I'm trying my best to actually address exactly what you are saying, but it's a tough route to go. Noobs will be happy for my efforts here regrardless, but I guess the bottom line in this venue, don't crash, it's expensive.. Thanking the lord above for these little indestructables on the cheap, we have such an army of new pilots to teach, we won't know how to handle them soon people. God help us the now old timers "the bulk of these boards inducted automatically as of now" we have much to teach these new pilots.

jobu; thanks my bub, I'm just a bored old man have'in some fun!! There gillow gliders, abit more $ but well manufactured an consistency from plane to plane a must when your use'in two or three per ,your bub, stevecooper PS. GreenAce92 Tail-dragger's for ease of set-up an land'in and tri's are fun too, Oh Well!

Hey steve check out the video on this link im posting they have some sweet planes. I want to try building the Varakoroff i think its called its a pusher with 2 ramjet engines on the booms of the fuselage. Check it out im sure you will be surprised by the designs. Unless you have already seen this show.

Quick question has anyone ever tried building the Flying Pancake? The experimental lifting body with the 2 propellers on the side. Its a pretty sweet design i think.

Default flying pancake

It is a sweet design, you can find plans for it via. freeflight rubber band version off of the web. I will be building one soon enough, it is a sweet design, in fact, the full scale version rivaled the jet's of the time speed wise. It also had the advantage over them being able to take off and land on a shorter runway which would have given it a huge advantage being launched from an aircraft carrier. They should have kept them in service, it would have changed how we think about aircraft design in general.

Default Chance Vought V-173

Hello Greenace,
I believe the "Pancake" design you're talking about is the Chance Vought V-173, also called the "Flying flapjack";
http://www.daveswarbirds.com/usplane...t/flapjack.htm
http://www.vought.com/heritage/products/html/v-173.html
The prototype indeed did fly, in 1942 and '43. Top speed was 138 mph, hardly "rivaling the jets of the time speed wise".
There WAS an prototype advanced design, the Vought XF5U-1, that was to have larger Pratt + Whitney R-2000-7 engines, and the projected top speed was 504 mph. However, this design never flew.
http://www.vought.com/heritage/produ...ml/xf5u-1.html
It would make an interesting model, good luck!
Ron
