Servo: Hitec HS-55

Rating:

Application(s): I am not a Hitec fan, after losing a new plane to a 485 failure, but I inherited a bunch of these. Some were new, others used. Put them on a Hitec servo tester, and out of 22, 12 failed, just stopped working. Doesn’t give you a lot of confidence. Come on Hitec, what’s going on? Needless to say, I will not be using them. Just isn’t worth the chance.

Comments: Nothing in this world is perfect, but the failure rate of these is completely unacceptable.

Servo: Hitec HS-485HB

Rating:

Application(s): Hanger 9 Twist 60

Comments: As I said in my last review, just quit working. Today, a club member had his stop working on aileron. Luckily, plane was on the ground. There’s a problem with this particular servo. Stay away from them.
