  Application(s): T-Rex 450 and Tarot Pro 450

  Comments: I have never had an issue with these servos. Yes they are inexpensive but they still perform as well my align servos. I have over a thousand hours on my Tarot 450 that run these servos for the cyclic and rudder. They have never once failed me. I plan to buy more to begin my next project.

  Application(s): Cyclic servos on 450 Pro heli

  Comments: Of four 933's I bought for my 450, one jittered around neutral. I always buy at least one spare servo when using cheap servos.

  They are a perfect fit in the 450 Pro, and the gear train is reasonably tight. On a servo tester, the speed shows as 0.13s @ 6v, rather than the claimed 0.1s. They work pretty well on the 450, however.

  The cases are fragile, though, and break quite easily in a crash. I fitted some weak HK blue servo arms which helped protect them until my last big crash, when the mounting lugs broke off both aileron servos.

  As a stop gap, I even rebuilt the heli with the aileron servos fixed to the main frames with double sided tape, which actually worked well.

  I ended up buying Align DS410's to replace them, however, and the heli flies noticebly better with the 410's.

  I rate the 933's four star for their decent performance at a low price - the cases are too weak to merit a five star rating.
