So how many teeth does the metal gear at the top where the servo arm attaches have?

Does anyone know if this will fit the Quanum Trifecta? I am looking for a digital servo to replace the TGY-9018MG

Hi, when I look through the case I can only see steal from (from motor to output), could not open it because it is installed on a plane. Very nice servo, would buy again.

Can someone confirm that these servos have a 'full' metal gear drivetrain, from motor pinion to splined output gear?

This is the most pathetic and disgusting servo i have ever used.Do not go for it please.The movement is very shaky and trembling.The gears are uneven and irregular in shape.
 simon.castle 616 points
n-nikem if the gears are so bad could you upload a picture for us all to see, is it just 1 servo, did you get more than one, is it all of them. I just received 2 and Im very happy with them. Also your half amp stated below looks more like the stall current, mine dont pull much at all without load. May be you just have bad ones. or they fixed the problems.

I'm using these for more than a year now and can't report any issues. Very good servo.

maybe you just got a duff one!, I have this servo in a HK 450 Heli with a standard 401 gyro and it performs fine, not juddering, stalling, or missing any control input, running this for more than a year with no problems at all. good servo, can't fault it

Cheap metal servo, but it seem not precise. I can not setup the neutral position for my HK 450 blade pitch.

If you dont like the smell of burnt carbon brushes, DO NOT USE THEM ON 6V! And look what ive discovered. This servo has the same size gear set with hextronik 900 micros. I placed the gears to my 900s and they are working flawlesly now, more precise, faster and i can use them on 6 volts. The only differance cap part is a little high to accept a bearing, so you have to cahange it too. Believe me, you will like the blue black servos, try it...

Tried 2 of these servos in an Electrifly EP-Su31, elevator, and rudder, works ok, but.... too much play in the gears. When you move the horn with your fingers, there is a noticeable amount of play in the geartrain. Also, very noisy operation.
Good price, appear to be digital, but I wouldn't use them in my heli because of this.
Will be changing them out of the aircraft for the HXT 900.

Just got 3 of 'em and shortly tested them. They have on one side a terrible overshoot during fast movements! Be aware of that!
The rest seems ok at a short look.
