February 4, 2020Application(s): Slope soarers
Comments: Slope soarers can take a pounding in heavy landings (such as I have demonstrated too often!). I have broken plenty of clevises, control horns and even servo arms. But I have never broken a Hitec HS85-MG.

January 7, 2013Application(s): Steering Servo 1/16 E-REVO Brushless
Comments: I have gone through 2 of these is less than 3 batteries being ran through a 1/16 E-Revo VXL. I was not bashing the truck. I was at my local track. Both times the same, ONE plastic gear that is in the case has stripped. I contacted Hitec to see if I would be able to get a FULL METAL GEAR set and they said it is not available for this model. I'm doing research to find a better servo.

January 13, 2012Application(s): Various fast moulded gliders, powered planes etc
Comments: Very, very reliable. Very, very strong. I have crashed these so many times and they never strip, never fail. These servos really cannot be faulted - except that some people feel they a rather boring servo, no digital bling or anything like that. They simply get on with working really well.

Comments: probably one of the best alternative servo for the erevo vxl quick ,responsive and powerful enough to steer the little beast!!!
