Ok, i set my Servo horns as close as possible with my stock TX, then i aligned the bell cranks @ 90, i turned down my swash links down because i have the align main shaft and got the swash level.


Ok, i go to check my pitch. I have +6 at mid stick, -4 @ bottom stick and +15 at top stick. The swash is really low when at bottom stick, but still no binding. So i'm guessing i shouldn't lower my swash any more, So should i mess with the bell mixer links to get my pitch set up correctly.

How do i know how low the swash plate should be, and vis versa for the top stick. Also, where should it be at mid stick? I'm sure i'll run into more questions, but for now this is it.

I was gonna say adjust the swash links to bring the swash down but if it is already low then you are gonna need to adjust the bell links to bring the pitch on the blades down. Your pitch range seems about right (around 19-20 total) so you just need to get the mid stick to zero which should give you around -10, 0 +9 .

The important thing with the swash is that when at full negative and using full cyclic you are not having the swash foul on the collar at all.

Well, at least it's close. I get Full positive 10 and full neg i get -9, should i leave it that way or make it -10 and + 9

Its all Mathamatics :)

+15 + 6 -4

Bring down swash so center stick = 0 and you get

+9 0 -10

then fine tune from there to get +9.5 0 and 9.5
