Well it's been a month of flying these servos in my Compass6 Hvu heli and they are flawless in performance. I highly recommend these servos. I can not tell the difference in performance between these servos and comparable align servos that cost 3 times as much. A no brainer and will purchase more in the future.

I have 4 or 5 of these that I have been racing/playing with for about 2 years. They've been run in Associated T5M, B44.3 & B5m, Losi 22B, 22T & XXXT, Traxxas Slash, and a Wheely King. I started using it in the Wheely King as a cheaper alternative to Spektrum 6040's, and it worked so well I now use them exclusively. I race on offroad astro and clay. The servos are fast, inexpensive, have good torque and I have not had a single failure. I highly recommend for any 10th scale racing.

Well I've had about 4 flights on a Compass 6HVU and they are performing very well. I was a little hesitant at first to use these servos at a 19.99 dollar price point but I have turned the 6HVU into a 6s slow headspeed machine and thought let's just give em a try. I can not tell the difference between these servos and the Align ds615's that I usually use, they feel the same in the air. I only have 4 flights on them so well see how they hold up. I will give another review in about a month. One thing for those who do buy these is you should drill out the servo horns where the main screw goes in cause its a tight fit and will cause the screw to not align into the spline correctly which will cause you to strip it. I almost did but caught it in time and drilled them out and it was a lot easier to screw it in align without cross threading it.

Nice item. Ordered 3 for a 550TT. You'll need spacers to give the right clearance in the frame though.. either washers or I used Align Carbon Servo plates, which work well although not cheap. One of them was a bit notchy, so stripped cleaned and regreased the gears... solved and silky smooth. No problems.

A perfect servos not only for helis, very useful if you need fast and strong ones for a plane model. Runs very smooth, centers perfect, has a lot of torque and speed. The overall quality is very good. This is not a cheap servo, it`s a true bargain!

Great servo, over 100 flights installed in the elevator of my Yak 40E running on 6V BEC. Incredible speed, awesome precision and torque. Has taken a lot of abuse from 3D and high energy maneuvers. It is really worth the price.

For the price a good servo. Speed is very good at 6 volts. The servo do make a lot of noise (high sound) that's very irritating,
