Hello all,
I'm looking for brushless motors with a hollow shaft to drive a propeller. The only motors I can come up with such hollow shafts are gimbal motors.
My question to you, is there anything against it to use gimbal motors to drive propellers? I haven't seen it happening except for this one: http://www.hobbyking.com/hobbyking/store/__61431__DYS_Brushless_Motor_BE8108_16_100KV_for_Multi_Rotors_Gimbals.html
What makes this gimbal motor different from the rest that it can be used for driving a propeller?
I'm looking forward to your replies!

Gimbal motors have very low kv. They won't produce enough rpm to swing a prop. There are a few counter rotating setups that may have the shift you are looking for, or just have one made.
Gimbal motors tend to be rated at about 2Amps and have 80turns or so of wire, and limited to about 12v.
The linked motor is capable of 8.6A, with a Kv of 100, for 6s (24v) to 12S (48v). It is for large slow turning props (23" on 6 cells, 18" on 12cells).

Anyone? Did I post my question in the right category?
