Novak brushless & hitec digtal servo

[semore]

Hey all I was wounderinig why my digital servo is stop working for about 3 or 4 seconds and one time in the a mains it complettly stopped all togeather untill I powered the car off then truned it back on.

now this is what I have done to trouble shoot tthe servo. I have tried it my otther B4 and dit works great. I have triedd other radios also even spektrum and it still freezes up.

Thanks Semore

the hitec servos are well known to be good, but they do have one weak point (as almost any digital servo, more or less visible) : the amp consumption !!
these digital servos pull around 1,5 A with ease, so if the car´s steering is fried or in any case hard to move, or the situation where the car is driven, it will draw even more.
some bec circuits cannot provide these amps for longer time, they overheat fast, so it stutters (as it isn´t feeded with "juice" any more so it fails.
the only workaround:
1. another servo with less amp draw
2. check full steering linkage at hard to move parts
3. use aftermarket bec, best: with cooling fins on it

these are the best ways to overcome this problem, good luck !!

Endpoint adjustment can do it to. If your radios endpoints are set correctly, each time you hit full lock, you kind of run the Servo against a Stop, this causes excessive current usage, and ultimately is bad for the servo.
