How good could they be ? Review by Chris Gayson
Buy a few and find out . They work in LARGE and small aircraft ! No TowerPro Fails . (Posted on 1/18/2016)
Good metal gear servo. Review by Eric A Miller
I used a couple of these to replace the TowerPro MG90s I was using in an EPP profile jet of mine. They're a little longer from the bottom of case to where servo arm is, but it was a good fit without any modifications needed. The aluminum gears do make the servos a little bit lighter then the MG90s, even with the aluminum case in the center. So far, I haven't had any problems with these servos, and Graysonhobby got them to me in two days from ordering! Great job Graysonhobby! (Posted on 1/10/2016)
Good price, great quality Review by SandyGabby
I have purchased 20 of these from Grayson Hobbies and they all are installed and working great.
4 are in combat wings, 4 are in a .25 sized float plane, and 12 are in 3 TechOne 3D park fliers.
Strong servo with good return to neutral. (Posted on 10/2/2015)
