x2 problem,,Beastx or servo?

[crickr1]

I have an x2 stock electronics (gaui servos),
Futaba 8fg tx,
6203sbus rx.
After 3 batts the other day, I went to fly a 4th, and had a tipover, left side, upon take off.
First I assumed it was stuck in grass, but tried again and realized it was the heli.
at home on bench checked over and everything seemed fine except upon pitch input
aileron(ch 2 on beast) servo was not moving. It works fine on cyclic inputs but not on pitch?? Tried a reset on beast and no change. I can feel servo wanting to move on pitch input but it won't. It seems to move fine when operating on cyclic just not pitch.
Could it just be servo going bad? I don't mind replacing but didn't want to just buy it if something else is wrong.
Any input appreciated,

Thanks fellow freaks

First unplug the motor and try these things:

Try to swap ch2 - aileron with another channel (elevator for example). And see if the new situation has changed anything. Now try to move aileron's servo but observe elevator's servo. If the servo is moving (now we are talking about elevator's as an example) - that means your aileron's servo needs to be changed or at least gears inside it.
If the elevator's servo is not moving - that means problem maker is beastX.

you could go into Step G. That will let you test each servo individually. Just FYI, I had a blade strike last month and its still not flying right. I think small amounts of damage and really throw things off. For example, I know I bent the main shaft and repalced it. It was only bent a little but would not fly at all. The feathering spindle does not look obviolsy bent but it might be bent a little. I dont have a spare yet so cant check that.

Your issue with servos whould be easy enough to isolate between the servos, the BeastX and the TX.

If the servo moves with cyclic, it does not sound like the servo. Check your TX and make sure, the pitch curve didn't get reset.

Thank you guys,
Emil, after I posted the thread what you said dawned on me so I tried and the same servo was acting up. So led me to Beast. I started going threw all my settings again,( as I said flew 3 packs already with no prob) I did however fly my Protos in between, As I went through my beast settings,Step G?, servo centering ,I noticed they were not responding correct. Very slow response to input. Went back to TX settings ,low and behold my swash setting was not on H-1. Don't know how it got reset, but somehow It did. Guess going back and forth with different Helis, and i may have been changing some setings. It happened!

But at least no damage.

Lesson learned, use caution when making changes at field, and pay closer attention to pre-flight check.
Resolved and thank you all

The most important thing is that you have solved the problem without any additional costs




Happy flying!!!
