Ball on servo arm, How far out, Cyclic and Tail?
« on: June 30, 2015, 10:07:50 PM »
Bought a used E7SE
Did not get stock servo arms.
How far is ball out on horn for cyclic as well as tail?

Ive got my E7-SE tail servo arm ball at 16mm using silverline vbar.  Setup per the vbar instructions it takes 132 CW (slider in) to reach full mechanical throw.  CCW (slider out) 150 points is all I can get before the slider comes to a stop still short of the end.  I think this is pretty much the practical limit anyway since the ball is starting to bind on the slider at this point anyway.  Since CCW is pro torque anyway I don't believe it is going to limit my authority and the tail does perform well.  Still can anyone running the Vbar on this heli answer the following.

1. Would it be worth it to lengthen the servo arm in order to get these numbers down closer to Vstabi's recommendations?

2. What is the practical or reasonable limit for tail pitch in degrees?  I know this has been discussed elsewhere ad nauseum but would like a Synergy E7 guys thoughts on the matter.
Trying in vain not to anger the gods of vertical flight!
