June 15, 2016Application(s): Steering servo for a 1/10 2WD buggy
Comments: I bought a Durango DEX210 V1 2WD buggy second hand which has one of these installed in it and so far it working without any problems. It does not make as much noise as Savox servos does when trying to hold it's center.
I will rate it as a 5'er. Although I must confess I mainly use Xpert RC servos in my cars as I really like them and they have by far the best specs for what I need and want from a servo.

Comments: I love these servos and i have 3 in all the models i race and so far the only issues i have had are the gears stripped out on my truggy and in my buggy it seems the mounting tabs broke off on one side :-( not a huge deal if only i could find the replacement top case ....

Comments: Have 2 of these and been very happy. They are really fast and seem to have a nice long trow range When one broke it was replaced quickly by AE @ no charge. Can't ask for better service then that!

December 11, 2011Application(s): 1/8th truggy, buggy and MT steering servo
Comments: Great servos. One of my favorites. Very smooth, precise great mix of speed and torque. Centers perfectly. Have four doing steering duties in different cars. No issues at all with their performance but I wish they used standard Futaba splines. Same tooth count as Futaba but Futaba horns feel very loose on these servos so I don't like using them. Other than that they are a perfect servo.
I would maybe give them 4 and 1/2 stars if I could just because the odd sized spline but since I have four of them for more than 2 years and with zero issues I am going to go for 5 stars.

December 11, 2010Application(s): .50 size nitro heli Throttle, Pitch and Cyclic
Comments: I have run these servo's in my helicoptors for over two years with the last six months on full 2sLiPo votage. They centre well and the factory quoted spec's are more acurate than other brands. I have deducted one point due to the spline being an odd size, the spline count is the same as Futaba but futaba horns are a little loose to be considerd reliable. to add to this the Ace horns are drilled at every other millimeter either side of centre meaning you have to drill matching holes for push/pull setup's
