I've got one 8611 on pull pull rudder on a hangar 9 sukhoi with BME 105 and it does the job nicely. With a big wheel, though, the play in the output shaft bearings is readily apparent. The big blue hitec has just about the same torque on 6 volts with almost ZERO bearing slop. I may change it out - will have to wait to see what happens as the flying season goes on...
