May 29, 2014Application(s): Team Losi XXX-SCT
Comments: This servo performed great. I would buy more. It was faster than most stock servos and the torque was just right for a 2wd short course truck. I tried it in my slash 4x4 it worked ok but it needed a bit more torque. so i put it back in my 2wd Losi.

July 26, 2013Application(s): I am using this servo for both steering and throttle/brake applications in a Traxxas Nitro 4-Tec (I am running a TRX 2.5R as the engine).
Comments: This servo is good overall. It is fast, durable, and makes a great throttle/brake servo. However, it really has too much slop in the gears to make an excellent steering servo; will be replacing it soon with a more expensive low profile digital servo.

April 29, 2013Application(s): Came RTR in my Losi night crawler as a steering servo
Comments: This servo did not have enough torque and was a little bit slow for what i want it to do

May 29, 2012Application(s): came rtr on my 1/8 scale proboat hydroplane. eventually used them as elevator servos for 30cc bird.
Comments: reliable reliable reliable. although i destroyed one attempting to "manually reverse one. the board was directly welded to the motor and i dint see a pot. so i learned the hard way lol good servo none the less.
