As is the DT750 thread, these two links are somewhat related. (this is a 3-rotor helicopter. I really like it.)

The first link contains a list of most of the parts, but is missing some little things. It is built to take abuse and be cheap and cheap to repair. It also does not need counter-rotating props. The ESCs are an important part, to make a very stable helicopter you need to change the firmware, or use Castle Creations ESCs with a specific firmware. More information on that is here: http://www.rcgroups.com/forums/showthread.php?t=1513678 Or you can buy pre-flashed ESCs here: http://abusemark.com/store/index.php...products_id=27

Please feel free to PM me if you want more information, or post in one of the above threads.

Also I think that multi-rotor helicopters are very different from sikorsky helicopters and, like when comparing airplanes to helicopters, that needs to be taken into account. I like them because there are less moving parts, are simpler in my mind, and there is no tail rotor, which I believe to be a huge waste of energy, as it provides no lift or thrust.
