Pour le prix rien à dire sauf peut-être un peu de jeux dans palonier. Donc bien serrer la vis

Bought this for my Associated RC18MT, the splines where a direct fit but the body is just slightly wider so some modding was done to make it fit.
The servo is smooth and centers very well but it's seems a bit loud so i'll have to drive it a bit faster then ;-)

Habe 2 Stück davon in einem kleinen leichten Modell verbaut. Das Modell ist jetzt 2 Jahre alt und war vielleicht 20 mal in der Luft.
Heute fiel ein Servo mit starken Flattern aus. Zum Glück konnte ich das Modell noch ohne Schäden landen:
Hätte mir mehr von den Servos versprochen!

Good for Bravado. Should be better in metal version. Doesn't like shocks but you shouldn't do that. Come back very properly, neutral position always achieved.

Nice high torque, not the fastest servo ever and they seem to do okay centering, but the whine at center is pretty bad. I put 4 of these in the MX2 955mm EPO and sitting there with no input at all sounds almost like a chorus of dentist drills in the distance. I haven't measured the voltage draw at center, but that much noise makes me concerned. Maiden flight went well, the sound was my only complaint. Speed at .12 seconds is okay. I may upgrade to something faster as I get more proficient in 3D. Would recommend as a mid-level budget torque servo.

the servo arm rattles already on the shaft. Can not be used in a model airplane .
I thought Hobby King is testing the products they offer here .
I'm disappointed

Just recieved these servo's to put them in a parkflyer Yak.. 1 servo was broken when i tested it to his maximum travel range.. These servo's are in my opinion ok for a foamy indoor plane, but for parkflyers i would chose the one with metal gear.
