Default Almosrt lost a heli ....

Hi all

Just wanted to share my weirdest heli problem I ever had. I have a T-Rex 600 NSP

Went flying last saturday, had a blast doing tic-tocs, multiple back flips and side flips and generally just going ape with my heli. At some point it felt asif the head speed was not what it should be and that the motor was bogging down a lot and the heli seemed to be more and more out of trim.

Anyway, landed, went home later and cleaned my heli, switched it on to check why it was so out of trim and the swash plate was all out of cente and skew, my blade pitch range in angle up was not the +12,0,-12 degrees but more in the region of +14,5,-8 or there abouts?

It was asif either the servo's have "forgotten" where the centre is or someone took the servo horns off, turned them a bit and put them back on the servo's!

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.
