How many RPM does a r/c helicopter motor do??

Question

i wanted to hook a small carmera to one of them r/c helicopter but the camera is to heavy for the store bought r/c helicopter.

so i figure i could make my own seeing how its mainly about lift, able to stay stable in air, tilt(the main rotors) and back rotors.( i know its a lot more to it, but just to keep it simple.....)

the first queston is how fast or how many RPM does your store bought r/c helicopter do?

the next question is where can i get a motor that produce more RPM'S than your store bought r/c helicoper? and the last question is, to be able to lift about 1lbs or 3lbs or more( not including the weight of the motors and blades), would i have to use a gas motor rather than eletronic one??? cause i would like to hook up more than one camera including batteries.

Answer 1

Check out Runryder.com, you may find a kit is better than designing your own.  And a lot of the r/c helicopters used professionally for photography (including all of mine) are electric due to less noise, no smoke, and far fewer vibrations.

The lifting range you are looking at (1 to 3lbs) would be well sited for an Align Trex 600.

Answer 2

I know from my own experimenting that you will need a gas powered engine. You just can't get enough rpm and pure engine torque from an electric...

Answer 3

Designing and making a stable chopper is very difficult.

Best to buy a bigger chopper than the one you looked at, and get a smaller camera.

Gas (actually glow fuel, made of alcohol + nitromethane) is essential for adequate power.
