a lot of people see to do this for a final project for engineering. i was in personal contact with two university guys for a while too, so this makes about what 6 or 7 that i have come across.

i have also found that flying rc helis is actually a lot easier than flying DFs. the first time i got on an RC helicopter i had flown this many times, and i just got on the controls and flew it around without my instructor taking over on the biuddy box at all. DFs are fun that way.

i figured out that a lot of the power loss i was experiancing was becuase of vibration. not all of the power loss, but a significant bit. the motors are definatly worn a bit though. i talked to feigao about the motor things, and he said they warantee their motor, but he did not speak enough english to understand the words "4 rotor helicopter" so the thought i was trying to fly a 2.25 lb plane around with only 44watts input power, no matter how many times i told him otherwise[:@]

i think part of the problem i am experiancing is that i dont think my shafts heat treated correctly, becuase they still bend and stay bent, and they are made out of drill rod. the next time i start having problems i will anneal them and try again.
