What is the length on your tail servo horn on Vibe 50/ JR 770 Gryo with 8900?
Hi all:

JR manual stated 17mm but found the the push rod is not parallel (kind of slanted). Is this a normal or should I shorten the distance of the ball on the servo horn.

Any kind soul to advise?

How does it fly?

If ok, then no need to change the ball distance.

The rod doesn't need to be parallel, it just needs to work, it's not like CCPM geometry. Set it so the servo arm and the tail bellcrank are both at 90deg and then use the distance of the ball to tune the gyro response and feel, if that rod running back is level or not is completely unimportant as long as the 2 arms are parallel to each other and set at 90 deg to the mechanics.

I found the 17mm to be a bit too long for my tastes on that gyro and servo, and went with the next hole in on the servo arm. I think it's around 14mm.
