另外 用13T齿太大了
HK-2221-6 with a 10 tooth pinion, providing a head speed of around 3150 RPM: This is a good place to
start with this motor. You have all the power needed for just about anything except for the most extreme 3D
type flying.
HK-2221-6 with an 11 tooth pinion, providing a head speed of around 3400 RPM: This will get you all the
power that most helicopters can handle, and will allow for any type of 3D flying out there.
If you do try to go to a 12 tooth pinion with this motor, you will get a head speed approaching 3700 RPM.
This is bordering on insanity, but some pilots will try it. There are only a couple helicopters on the market
that will stay together with this kind of head speed, but for those that venture into this realm of power, the
sky is the limit! |
