It would be nice if they were all the same... or at least all the normal size seroc and then another size for the micros.

It was not really the controls pushing back on the servo but more the speed and torque of the servo pushing against the surface that moved the horn. We have servos that are so very high torque and super fast now.

One reason for the rant is so that Marcel realizes the significance.


He said;

Anyway, took the control horns off centrered the servo's put the horns back and heli was fine again, servo all working and had the correct amount of travel.

Under closer inspection, it looked like the servo horns actually slipped on the servo's!!!! I have HS-6975's on the cyclic, pretty powerfull servo's, so I guess that is possible.

Anyway, so from now on, I am checking the tightness of servo horns on the servo before each flight, that could have ended in disater.


The servo arm is the wrong one and needs to be swaped out with a correct one. Simply tightening up the screw will not fix the problem.
