I managed to burn 3 servos lately and I wonder if there is something wrong with them or there is another problem I should start looking for???
Somebody mentioned this to me in another forum and I wonder how much of it is real

Not good - I was warned that some analog servo's won't work with the new faster receiver
I'm using a 12FG with 2.1 software but it's not the sofware because the first servo I was running ver.1.6 I just wonder if these servos are not up to work with this system

The transceiver software does not have a relation to what you suspect to be an Rx to servo frame rate too high for an analog servo.
But the type and settings of the receiver matters a lot - what receiver was that - particularly was it the older "FS" or the newer "HS" one ?

It happened with two different Rx both are FS (R617FS and R6014FS) but anyway all the servos were digitals.

Just Fyi:} the tx doesn't have anything to do with the use of HS or non HS on the rx. If you run a analog servo in a HS slot ( 1-6) on the 6008HS on a rx that is in HS mode you will burn them up. I see that you have the FS rx's so this can not be your trouble.

What voltage are you running in your airbone system? Tom

Tom thanks for chipping in.
The first one to go was a servo rated for 6V and I was running the ESC programed to 6V on a rudder on the heli, so I knew binding wasn't the problem and I thought it might have been voltage but somebody mentioned that the damage didn't look like voltage.
The other two I knew it wasn't voltage because they were on a glider with a 4.8v NiMh pack.
That's when I started thinking of something else might be the cause, but since all of them were digitals and all my Rx were FS then I guess I just happened to run through na bad spell of crappy servos.
Or definitely Hitec's cannot take any abuse as all the other (Futaba's and JR's) servos I have because I have both of those on my bigger helis that sometimes I turn on with the blade holders on and you can hear them complain about it (yes, I know... shouldn't do that) but they still work great, so from now on I know which servos I will buy (and which ones I would avoid)
