Friends!
I have problem almost clouse to scubyfan...(project w/FLY PLATFORM).
I don`t have of experience in field RC Planes, but i have big experience as aviation engineer and inventor...
So, my problems are:
1.The second prop on my FP have to have:
a/ counter-rotation
b/ for 'tractor" prop pitch - conditional coll "negative" (tractor prop pittch -conditional coll 'positive")
c/ "tractor' pitch "negative" as far i know, don`t making.
d/ as rule blades of props making with unsymetrical profile, therefore it isn`t possible to use as pusher prop.
e/prop w/changing pitch, as minimum $105
2. Therefore my project under sword of Damocles....and lost money
3. Who have idea or recommends PLEASE
Thanks
