Excellant park flyer servo Review by Richard Smith (SandyGabby)
I have purchased 30 of these from Grayson Hobbies and 20 are installed and working great.
The remaining 10 checked out fine and are for future projects.
Strong servo with good return to neutral. (Posted on 7/4/2016)
Great little servos Review by Andrew Karmy
I got these to put into a couple of combat airplanes. They are great quality and strong with the metal gears. Still fairly light and should work perfectly for this use. (Posted on 1/28/2016)
great for 450X Review by Earl
I put these on the collective of my Blade 450X. They have more torque than stock.The stock ones stripped very easy. I have to flights and one crash and no stripped gears! (Posted on 1/3/2016)

I put them on the collective of my Blade 450X and they work great. More torque than stock. The stock one stripped all the time. I have two flights and one crash and no stripped gears. (Posted on 1/3/2016)
Best servos for the $ Review by Poporbit
I've purchased at least 3 sets (5/set) of servos from Grayson Hobbies. The first two sets were analog and the last set is digital. All have seen heavy use and operate flawlessly. I recommend the new digital servos for the greatest centering power, (ideal for rotating motors.) (Posted on 12/18/2015)
Review by Ken Daughtry
I have just begun to use these and, so far, I am very satisfied. Have been using GH tower pros for a couple years now and I am pleased with them. Good servos and a good price. (Posted on 4/17/2015)
Review by Chris Gayson
All 5 of these are in use now. No failures yet from TP servos in anything I fly. (And crash!)
(go figure for that price ) Just a reporter (Posted on 4/10/2015)
