pas mal pour son prix

Utilisé pour animer la direction d'un gros offshore rc, le GTY-552 semble fiable et précis. Il aurait mérité un boitier aluminium. Je conseil!

I've been using these for years now, never had a bad one. I have them in T-Maxx, Revo, Proline MT, Rustler, Slash, TRX4, and Axial SCX10-II. Compare to Savox SW1210SG.

Fast, but a lot of mechanical play after ca. 25 Flights in E-powered 50cc- Extra330SC

Nov 08, 2018

Servis are Fast, but after ca. 25 Flights in E-powered 50cc- Extra330SC, i noticed that the iGyro had problems to stabilize the plane in windy conditions and i often hat to do slight corrections in aerobatics. Was not very precise steering anymore.
Caus is mechanical play on all 3 servos, i had (2 on aileron, one on Rudder).
So the metal gears of this servo are not oo high quality level...
Problem now: cant find any spare gear sets for this servo in Hobbyking shop?

I have over 20 of these in various 75" ~ 88" Extreme Flight planes. I just tested the torque on this with a dedicated 8.4v power source from a castle bec pro.

Max torque was 411 oz with a 1 inch arm.

I also tested a Hitec 7955 and it was about 418 oz with a 1 in arm.

Since these wre mainly used by me with a bec at 8.4v - I was curious on it's torque and this test proved why these servos did not fail on the planes.

I have sold about 30 of these servos though my trackside shop. So far we have had 3 fail, 2 due to 'people' fitting too long a screw to hold the horn on, messing up the controls inside, rather than the screw provided. The 3rd somehow stripped a gear, but as it was the same person who had fitted a long screw, we just changed the gears over from one damaged one to the other!
We have tried many budget servos, and these I am happy to sell and use myself in my racing 1/8 Truggy.
In My opinion you have to pay twice as much, to get a better servo.
