Just found out that the nylon gears can't handle the torque. This servo lasted less than 3 hours in total and then stripped out a very tiny gear.

aball, I have the same problem. Opened it and one of the drive wheels has broken teeth. You need to find a replacement drive wheel kit. Unfortunately HK does not have it for this servo. Serch the internet...

Hello. Have a problem with one of these. Servo jumps 'back' while moving into one direction, and then it keeps going forward. This jump happens at a certain point while going into either direction. Could this be about radio transmitter or a broken servo?
 Hussain Joharji 204 points
Hello, in my oponion its from a servo, maybe the gears is jump while you moving it.. or the motor is jump and make a misalignment for gears..

i dont know exactly, so sorry...
Best Regards

Does anyone know the amp draw for one of these? I'm using a 60amp ESC which has a 3A bec, I am not sure if that'll be enough to supply 6 servos

Current Drain (4.8V): 8.8mA/idle and 220mA no load operating Current Drain (6.0V): 9.1mA/idle and 280mA no load operating Note: Stalled loads will be more.

Do you guys think, this servo would be alright, for a mini titan E325 Flybarless?
 Old Man 205 points
Get the HS82 they are almost the same but metal gear I have both types and both are very good but for choppers metal gear is better Cheers

Using this servo with a telebee gyro. The servo heats up. Tried with another HS 81 servo. Same thing happens. Why is this so?
