RE: ThunderTiger Rare Bear
Sessholvlaru, that's a shame about the dead-stick and a real pisser about the mechanical retract servo not having enough umph. Wonder if that servo would work on 6 volts? I have some 3-1/4" thin foam wheels that I intended to use, but if the purpose built servo can't handle your's I'm not sure what's up. I am using the Futaba 180 degree retract servo and the gear seam to cycle on the bench fine. I may throw a 6 volt battery in the system just to see if the servo operates.
For this model, I'm staying away from air retracts. Too much extra weight.
