here is a long post on rc groups dedicated to the
light flight bug. i got the idea to make this mainly from that design, and the
park zone vapor. after i was already done, i
found that what i created was similar to the i.f.o
i wanted something that floated around and could fly in a room, like the vapor, but had roll control as well as rudder and elevator. what i ended up with is pretty durrable, because of its flexability, and light weight.
here are the parts i used:
6 amp esc (could have gone smaller, but i did not have one that worked with 2s)
1.5 gr linear servo
180 mah 2s 15c battery
4.5x3 gws prop, i may also try a 5x3 to get a bit more air over the control surfaces when flying slow.
after some testing, the plastic coating was a little too flexible, and the frame flexed a bit much to. so i added the front to rear spars on each side, and taped it to the plastic, which helped both things.
also the plastic coated control surfaces were too flexible also, so i replaced them with 2mm surfaces.
i also moved the receiver up, so that the rudder servo and control rod was above the wing, this put the 2 elevon servos at about the same height (before when they were at different heights, the movement was not even).
i added some epp foam bocks behind the motor mount, as after a few nose in landings it was loose, this helps significantly.
