Are 9257's ok to run on the swash on a fb 500.

If you're not living on the edge you're just taking up space !

I think it's been done successfully, the 9257 is fast, but has about half the torque of the more commonly used 9650.

The torque issue is what's bugging me. 9257 is a little lite on torque. Hate to dump this thing over weak servos.

Before Ron Lund re-did his site, I believe he was selling a combo of the 500 that used 9257s on the swash as well as the tail. The flybar does act as a servo amplifier, so perhaps the 9257 will be OK, just don't expect stellar performace with respect to collective. The servos may be fast, but with a low servo torque value, the speed may not be an advantage.

I bought a set of 510mg servos. Rather spend a little now than alot later.
