Not too happy with these servos. Got 3 of these for ailerons and elevator in big sky cruise 2400, just because wanted to put trusted ones and Turnigy S3101S in flaps and rudders. I can say that Turnigy servos are 10 times better. These servos definitely not very smooth and centering is far from ideal. Looks like you just pay 10$ for hitec label an 3 for servo.

Good price. Pretty fast too. I tested the stall torgue at 2032 grams/cm. The D-MG16 only pulled 1435gr/cm. I fly gliders with it. For flaps I use HS 82MG.

I bought two and other one has this problem right after the first few flights (no physical damage can be seen). I mentioned about it in the discussion. The servo moves alright, but "goes reversed" or stops for a while in a certain point and then continues in the original direction. This is very annoying. And the reason isn't in the transmitter, I located it in the servo itself.

The other servo of the two works alright and I could recommend that one, hehe. So "choose" a good one.

I bought one for my tail HK 500 helicopter, to be compatible with my Hobby King 401B Digital Head Lock Gyro AVCS .... did not get further researched and saw that a servant is very good ..... and has a great value.
