2 burnt up micro servos /Front Retract WHY??help

[Indydrt]

Really pissed now.. just bought another hitech 5065 servo today micro and within minutes its poop what am i doing wrong..i have a scale 500 trex with the battery is a 6 s 3700 i also used it with a 3300 6 s align ..is battery to big?? using a Spectrum ar7200 beastx, ,, does the voltage need correcting??
happend twice already on the bench.used just for the front retract on a scale a109

[Dr. M]

How are you powering the servo? you're not plugging it into the 6s pack are you?

BTW, the HS 5065 takes a max of 6V.

[Indydrt]

Thanks dr.m for responding,, im just using the 6 s pack hooked up to the speed controller wheich is then going into the beastx ar7200. Then i selected aux 2 and have a harness spiltting the rear servo for the rear retracts and that ne works fine. But a larger servo i forget what it is ..and then the micro up front.? So you think battery might be to large volts etc?

I forget what the volts are. Is it 22.2 on a 6 s. ?

[Dr. M]

No, the battery isn't too large. The ESC has a DC-DC converter called a BEC which powers your electronics at a lower voltage. If you can setup the BEC voltage, set it to 5V just to be safe.

Thanks. Thats what i thought it was supposed to do,,, a bec.. Yes,,if i can find out what brand mfg the esc is. I will try and see how i can adjust it ...if can thanks.,,dr m

Dr m. I wonder if i have to adjust the pulse settings for servos in aux 2 ,,on original setup in the beastx,,i know i did it for the cyclic and tail originally . But not for the aux two ,,if there is even a setting for that... Also maybe i need to select a different channel on the beastx..this aux 2 was the only one that worked,,that was a pain in but also just getting that to work.so....hmm. ???

[Dr. M]

The HS5065 servos are 1520µs 333Hz. If you're trying to run them with a different pulse width (like 760 or 960µs) it will burn them out. I'm not familiar with the BX controller, you might want to go to the Best forum and ask there.

Which port are you using on teh Beastx - there isn't one that the manual refers to as Aux 2 - there is CH7, but the manual says ...
"On slot [DI2 | CH7 | CH6] another auxiliary channel is available on the top pin [CH6], for example to hook up a governor for nitro engines. Please note that this slot is only issuing a control signal and has no power. For this reason a servo cannot be plugged here directly. The two lower pins [DI2] and [CH7] are reserved for other applications."

First let me be absolutely clear its a AR7200 bx FBL Controller and reciever..
PORTS read from top to bottom if mounted vertically as it is on my 500

Aux2
Aux3

Aux 1

Thanks for your help lets go from hear.. Hitech said to me today that this hs5065 digital servo will not take more than 270 htz.

And the other tech i think Greg said that i should not use a Digital servo for the retract.. ok i said.. but i use a digital ds821 for my rear two retracts with no issues.. so go figure,,, so i just bought a analog hs65 mg not digital and iam going to try to lower my settings in the beastx assuming iam setting that also controls the aux 2 channel but i looked and cant find anything yet well nothing from the manuel yet

Sorry - hadn't picked that up, now seen it in your first post

[Indydrt]

no prob and i also just made a new post in the beastx forum to see if anyone knows of an adjustment for a aux 2 channel theres nothing in the manuel for that channel .

[Dr. M]

I believe that channel is directly controlled from the Tx. The BX has no input on Aux2.

[Indydrt]

Ok hmm.
