After 1.5 gallons of hovering and slow FF i discovered that I could move the pitch servo axle sideways. Swapped the servo with my throttle servo that seemed ok. After som FFF, inverted climb outs, loops and tic tocs ( 3 tanks) it looks like the axle is slightly bent. There are no bindings.

Isn't the JR ES 539 servos any better than this? Would the DS-811 be a better servo for pitch?

Hi,
What model class are you flying?? ie 30,50size etc

The macgregor web site has a section that lists recommended servos for each class of heli. You may find this helpful.

Best Regards

Don't say "Crash" say "Ground Proximity Incident"

Found that the DS 811 probably is to week to use on a 50. Got a Futaba 9202 I'll be using as pitch servo. Also ordered 2 JR 8301 that I will use on cyclic/collective. Keeping one ES 539 for throttle.
Will order 2 more 8301 servos (throttle and pitch) when I get some more money to spend!

Well, the answer is 539 is crap!
First I had 1 servo (pitch) fail. Got a lot of slop sideways.
Yesterday while in inverted hover I couldnt flip it sideways. Got it down ok (thanks RealFlight) and checked ail. servo. No respons. If I helped the servo to turn it would a little bit an then stop. Same both right and left.
Now got dig. servos on cyclic and kinda like it!

The 539 is not crap, just that you are asking the servo to do more than it is capable of! The 539 is just your cheap box std servo...fine for throttle duty but anything else you are simply overloading it and waiting for a failure to occur.
