General Servo frequency?

Wonder if anyone can help? I have searched the net and have not found the info I require. I have 3 EmaxES9258 servos Can anyone tell me what frequency that operate at i.e. 1520u at 250Hz or 333Hz or 70Hz. They are digital servos with metal gears. Cheap, yes, very. I have burned out 2 of them so far but can not find all the info on them. Cheers. Incidentally I have two heli on the go at the moment again . Yes , I know it won't last but I am being very, very disciplined and gone back to basics. Tail in hover, side on and get that imprinted on my brain before I gone on. All the best.

Thanks Slobberdog very much appreciated. Spent hours and could only find speed not frequency. I don't think it will make any difference they run very hot even on a very sloppy tail so need to get something better.
Also the same with the Assan gyro. I have 2 and both sort of half failed. They do not respond to the programming any more. It seems to be quite a common fault reading on the net. I flew without the gyro yesterday a couple of times.
Difficult but not impossible. Just needs lots of practice and of course when you do not get it right a spin starts. Thanks again for taking the time. Cheers
 
It will always be 1520us, it's the hz that you need to look at. I would start at 70 and see how the servo does. If it's slow or doesn't respond the way you think it should, then raise it up to 200. I would NOT go above 333hz though. Make sure to keep an eye on the temp of the servo after EVERY flight. If it's getting hot, lower the hz.
