I have hitec HS-85BB (approx 35oz of torque). I have 4 of them. I'm currently building an unpainted kit Bell 222 50 size. I need 3 mini servo's to power the retract's (retracts in the mail from century). Are the Hitec HS-85BB enough to power the retract system? I have never played with a retract system - does the retract locks in position or does the servo hold the position? The heli will weigh close to 8 - 9 pounds when done. is 35oz enough torque or holding power?

I used the same servos on my 60 sized Airwolf. The retracts lock into position both up and down but you may need to play with servo arm lengths and endpoints to make sure the servo is not stalled at extremes. I was using a WCII transmitter with the two rear servos on a Y-lead and the front in a seperate but mixed channel. Also the WCII has a servo slow feature which meant the wheels went up and down realistically. I see you use JR, I think you loose the servo slow feature in Heli mode, but you may have it in one of the first two prog mix menus.

I'm expecting the retracts and servo to arrive today or tomorrow. Thank you for the info.
