Fusion tail servo arm length

[3dbasher]

hi just wondering what is the optimal tail servo arm length to use? i'll be running 2100rpm ish.using 9256 tail servo, ar7200bx with 95mm tails.
Hoping to get this thing test flown at the weekend I've forgot how long I've even had the thing lol

Hi, if I remember right its 16.5mm from centre of servo horn to pivot ball, normally not too bad with the memory! I've got the velo50 so will be the same for Fusion buddy. Hope this helps.

I also Have a velo 50 and its different because it goes through a bellcrank, on the fusion it direct off the servo....also my velo has a skookum on it so not really a good reference lol
