Scratch Built Snowspeeder!!!!!

[pitviper51]

ok heres a few pics of the glider,, i tryed gettign inflight shots, but seeing im tossing and shooting at the same time nothing worked hha, ill get some tomarrow i designed this for a science project in 11th grade,, the teacher couldnt belave it flew... i thought about a powered version once, might still try it.. cg is about middle of the ship for this one, still needs work tho..

pitviper51.........Looks cool!!!! I like the concept of the tail fin. I alway wanted to try a hat cam so I could record more of my flights. This way where ever your looking the camera will follow!!!

one thing i would highly suggest puting some kinda of vertical fin on it,, even a clear lexan fin would be better then nothing,, i tryed to thing once with out a vert stab, and it would slide so bad haha then spin wildly, tho yours is a bit differnt more of my 2 cents

I think I could be done as is. If changes need to be made I would simply consider making control surfaces like on a b-2 stealth bomber. It has yaw control without a vertical fin.

You know, if you end up with stability problems, as an alternitive to doing non-scale lexan fins and stuff like that - just install some pizo gyros where needed to keep the thing going in the right direction.

i did more test on my paper design,, one things for sure down slow down hahah, im sure this will hold true to the snow speeder.. the b2 controls yaw by use of clam shell airbrakes, would be neat to see on rc

John,

I love it, and wish you the best...but....
You've got major anhedral there. It's going to want to flip over on its back big time. Be prepared to fly inverted, or better yet, drop an FMA Co-pilot in it.

Good luck

John,

Flying wings are normaly closer to 20% to 25% of the area ahead of the CG. I fly a Pizza Box Flyer (Flat plate, 24 x 24 square) and it fly's great with the CG 5 1/2 inches back from the leading edge. That's 23% more or less.

Others have suggested a glider test. It's always a good idea.

Very low aspect ratio designs have a lot of effective dihedral. That's positive yaw to roll coupling. It may help to counter all that anhedral.

Yes, bigger diameter lower pitch prop the better. With all that drag it won't be fast anyway. Don't overload the motor though.

Best of luck.

I think it will fly. If is doesn't it will still look really cool crashing Good luck with it.

R.D. ...... My nick name at our feild is " Mr. Inverted " ... My brain seems to function well this way, so I am prepared for the worst . Now getting it to flip back over is the ultimate challenge.. I am just about finished with my glider version and will be taking it out this weekend (hopefully).. Thanks for the good wishes!!!

Jay ... My sentiments exactly!!!! If it does crash I will be posting a special effects video . I need all the luck I can get!!! Thanks.

good luck John looking forward to your video

When is this thing going to fly? Must have video!
