elevator binding

[helidaz]

Hi All, l have just put a 6110e spekky rx in my Rapier 250.. now on set up the elevator servo is binding when near top pitch.. lm not used to set ups that much as was a rtf fly model but l got a dx6i cos radio with it was crap.. lm guess sub-trim in the manual but not sure how much to do to get elevator servo arm straight and stop the binding.. Or wil it be trial and error?? the pitch and aileron servos are fine... Any help would be grateful... many thanks..

I presume this is ccpm heli?
What you need to do is reduce the travel of either the pitch or elevator in the swash mix. There is a screen in the set up option that will have 3 sets of values either plus or minus say for example -60%.
reduce the pit or ele by say 5% to -55% and see if it is better.

Thanks for that.. will give it a go.. tried the sub trim.. didnt work.. at full pitch the elevator servo is being pulled downwards.. thanks again!!!!
