just done going over my other frenzy 50. i noticed that to get 8 degrees cyclic pitch, my swash mixing values are only 20 on ail and 20 on elev. is that okay? aren't my servo be slow on those values? but if i go 60/60 on ail/elev, i get around 14 degrees.

how big are your servo output wheels - you sound like you have a mechanical advantage happening - eg servo output wheels much wider than bellcrank width.

i'm just using the regular hitec servo horns. everything is perfectly set up mechanically at 90 degrees midstick/neutral trims position. am i missing something?

Nope..
those figures just indicate the percent of movement of the servo,not the speed.
they should move just as fast,just not so much.
If youre at 8 degrees cyclic and have the pitch where you want it,and there is no binding,you should be good.

it's better to ask for forgiveness than for permission

How are you measuring your cyclic pitch?

@zane
with all stick/trim neutral (mid), flybar is perpendicular with airframe if viewed from the top. i then place pitch gauge to paddles then measure elevator deflection (moved ele stick all the way to one side) with reference to a fixed point in the head. like wise for aileron, i position flybar horizontally aligned with the frame and measure ail deflection.
am i doing it correctly? or is there another correct way?

This will give you some crazy big numbers.

You want to place the pitch gauge on the main blades. Just rotate everything another 90 from what you are doing. The paddles shouldn't move (unless you have a phasing issue), just the main blades. Now measure the deflection. I like 8 degrees for my cyclic pitch.

Let me know if that works for you.

embarassing

thanks Zane. i'll do that. so it's the same as doing the collective but this time, instead of the throttle stick, it's the aileron and elevator.

thanks again
