Rating:
Application(s): 1/16 and 1/18 rc cars
Comments: Bought about 20 of these so far and haven't had one fail yet.
Good torque, centering and very reliable. Not as much power or precision as more expensive servos, but comes close. All metal gears seem strong as I've never stripped one. A great servo for a great price.

Application(s): RC heli 450 PRO
Comments: I have flied some 1000 flights with this servo on swash
on 450 PRO's. I like them, but they have a weak spot -
the "fasteners" on the case. They break easy on impact.
They can be strengthened somewhat by filling CA in the
"holes" under the wings, but they should really be redesigned
to not break so easy.
Still, very good for the price.

Application(s): Cyclic on 450 Pro heli
Comments: Being so cheap, I had to give these a try.
On the positive side, the speed on the servo tester pretty much matches the claimed 0.11s @ 6v - but all of my 929's had a horrible amount of gear slop.
In flight, they seem to work ok, but the heli just feels a bit loose. They worked better than Henge 922's, but not so well as Henge 933's, which in turn were not as good as Align DS410's.
I give them a three star rating only because they are so cheap.

Application(s): Cyclic on 450 size helicopter
Comments: Well it seems a good deal at start but after more than 100 takeoff, I can say these servos have many problems. 1st they can't center well and 2nd the gears have some play. I will never buy these servos again because even if they are not expensive, they are almost unusable on an helicopter.
