I managed to get the spacing just right. The synergy E7 is the only (besides logo600) setup I have ever had on vbar that has 0 points trim, 0 ponts swash level and 0 points needed at top and bottom stick . I would say I got the geometry for vbar perfect.
-I used the carbon horn behind the plastic horn on all 3 servos.
-ball facing the front.
-1 x carbon spacer from Trex600/700 (2-3 synergy metal servo plates) on the front 2 cyclics and none on the back cyclic servo.
-Used the setting in the manual for the servo linkage.
