    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.

    The plastic is cheep and broke on all three servos were they connect to the helicopter in +76 degree tempitures, and they were even mounted in rubber. Very fragel weak plastic, I havent seen plastic like that sence the 50's.

    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.

    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.
