Let me clarify what I mean with "controls pushing back"

Imagine your heli up in the hair, doing tic-tocks. As you flip over and you change collective from full positive to full negative. There must be a significan load on the swashplate that "pushes" back and that the servo's need to counter to change a heli's collective. Therefore the servo's will do as told and as they are so powerfull, they will just turn regardless of the force on the horns stripping the horns, specially if using the worng ones.

And as far as checking the screws are concerned. If they are not tight, they could vibrate loose, or even fall out all together as the servo turns but not the horn thus slowly pushing the horn away from the servo therefore less surface area in the horn the servo to hold on thus slipping ... You don't have to be a rocket scientist to know if you are using the wrong horns all together that no matter how tight you screw them on they will slip.

Either way, I had substandard horns on my heli (For my style of flying) A good flying buddy of mine organised me some of those nice thick red ones that comes with the servo's. I reckon they will be ok with those.

So, I am done here. This thread is getting out of hand and is digressing from my original reason why I posted it.

I just wanted to share an experience with everyone. And as infernorcteam so nicely stated stated. Maybe someone else out there might read this and not make the same mistake and be as lucky as I was.

Happy flying all ....
