Works great. I haven't had any problems with these servos. I have them in a Hangar 9 330 running at 8v.

I purchased 2 of these servos, as it was the recommended aileron servos for my Hangar 9 Extra 330SC build. No complaints, as they do the job and have performed flawlessly for me other than the servo wires coming loose from the servo plug. I replaced the plug with one of better quality and all is well. That should be improved for the price you way.

Used this servo on two of my quickie 500 for elevator and ailerons using life batteries 6.6 volts. After two weekends of flying, both planes flew (150 MPH +) rock solid.
Is now my Mini servo of choice.

I'm a fan of Horizon and Spektrum, however these are personally the worst servos I have ever used in a plane. I bought these servos about 6-8 months ago and installed them in my Hangar 9 extra 330sc 60e as HH recommends (just getting around to finally writing my review) and I ran these in my extra for over 25 flights. My first issue was 3 mins into maiden, in the air the servo chatter on left aileron was terrible causing oscillation and the plane to fly all over the place, we're talking 1 inch of back and forth chatter here. Luckily I got the plane down safely and contacted HH and spoke to a not so friendly rep implying this is normal but they will send me a replacement as a one time good will... while servo chatter on the ground, can be normal I agree, in the air however it's NOT. Anyway I received the replacement and the chatter was gone. The next and biggest issue with these servos (for me) is that they do not find center, literally every single flight I have ever had with these I had to re trim for level flight and often I would have have to re trim mid flight again. It appears some people have had good luck with these and that's great, I on the other hand would not recommend these to anyone. I have since replaced both aileron, elevator, and rudder servos with Savox and the plane flys level and true every flight with no retrimming required.

I like Spektrum radios and receivers but have always been skeptical of the servo line due to past experience with other people's aircraft and helicopters. I thought I would give the A5060 Mini HV Digital Hi-Torque MG Aircraft servos a try since they were listed as the recommended servo for my Hangar9 Extra 330SC 60e ARF (HAN9025). They looked very nice as I took them out of the boxes and installed them as the aileron servos. After that it all went down hill fast. They are very noisy servos at idle, always buzzing with do load on the control surface. Centering is none existent which allows for several degrees of displacement on the control surface when returning to center. You can cause the servo to displace from center by manually moving the control surface by hand. Gear train slop is considerable, well beyond what I am accustomed to. At a price of $59.99 I would expect a lot more quality. I would only recommend these servos for a trainer aircraft but only if no other servos were available.
