Micro servo
 

So one of my diff servos failed so I changed both for jx pdi 1151mg servos, plenty of torque and waterproof fitted then and was all fine, put rx lid on and both died can't believe it, tried other electrics in the slots and they worked so it's just the TWO servos. Most bizarre was running 7. 4v 2s. What's everyone else using?

Re: Micro servo
 

If you were running the servos at 7.4V you fried them. That servo states in the specs it is capable of running 4.8V to 6.0V. You need to set your BEC to 6.0V for those servos.

I was using a 1080 esc and wrongfully presumed. Thanks suicide shift ��

Re: Micro servo
 

Power HD is offering a replacement: the "Power HD PHD TR4"
Specs say 4.8V to 7.4V.
I have a set of them in the parts bin for a future project (or should I say: started project which is on hold because of other newly started projects ...)

Re: Micro servo
 

Yeah I see them, nice. And expensive. But then what doesn't seem to be?

Re: Micro servo
 

The TRX4 electronics all run at 6v, if you run the ESC at 7.4v output you will burn out the electronics. You do not need high torque shift servos, these things only have to move a simple linkage either in the axles or the transmission. The stock servos work just fine if you don't feed them too much voltage.

True ...

I picked up 3 tr4 servos In a set on eBay for like $57 pretty hard to beat.
