A scratchbuilt performance plane (with instructions)


This is my new plane, the only one i have that is in flying condition.
me and my buddy Alex build this plane in about 4 hours, and man is it good!
seriously this is the best plane ive ever flown, moves quick, can fly fast or slow, do loops and stuff. plus its nearly indestructable. i crashed it about 8 times already and all i broke was the vertical stab and a piece of balsa on the fuselage cracked, a little epoxy and its back in the air again.
some specs:
40" wingspan
3ch, aileron and elevator
tower pro motor with 10A esc i think
runs on a 3s 1000-1300mah lipo

this plane does not like stalling, if you stall and you dont got altitude, you are in trouble cause it starts looping thats how i mostly crash it.
handles great in wind up to 20mph

Try a bigger tail.
Might cure the slow speed issues.
The horizontal looks way to small according to TLAR.

no, its fine, the vertical tail is small because i will eventually put a ruder on it.
it does not need a bigger tail, the plane is so goodly balanced that only a little tap will send it out into the sky

Sounds fun!

My initial thoughts are that you need more stab and rudder area. It might balance fine, but there are more things at work than just CG balance to a good handling plane.

At high speeds, smaller tailfeathers work OK, but at slower speeds, you need more area to provide the same stabilization.

A stall that send the plane into a loop....well, if that happened on any of my planes, I'd think the CG balance was off. Too tail heavy, add some lead to the nose.

As you said, a little tap will send it out into the sky, again, sounds like CG is off- too tail heavy, add some lead to the nose.

Just adding a few things to try to help you get rid of the nasty stall.

I clicked on this thread from the RCGROUPS homepage because I like seeing homebrew planes- I like it. What wing are you using?

the tail has to be small as ive been told, the original inventor Alex made dozens of copies of the planes for his friends, is flies fast and slow with enought controll, you will have to fly it to believe it, ill ask Alex if he has a thread about this plane. well the looping during stalling is just the way it is, the wing is kinda shifted back and there is alot of nose area before it, so the plane cant get the lift from the wing from the motor during the stall, but you can get out of it.
the rule is for these planes: if you get in trouble slam on the throttle
well i'm not saying is stalls, its kinda hard to stall, but if you do, you are in trouble.
the wing was cut out by a hotwire bow.
this is the perfect plane almost, handles well in high wind and all that, but one negative is the stalling.
ill try my best to get you guys some sort of information on how to build these

Wing is to far back, I had the same problem with my Slow Stickbeing tail heavy and stalling when I moved the wing to far back toward the tail. But once I moved the wing quite a bit forward and positioned the battery closer to the nose of the plane to achieve the proper CG, it became a very mild flyer.
