: The center hub of the washout assembly the flat side faces up? That was my problem, now hopefully I can get things together again.
Is it ok if I lower my atv elev.to 86 86 and my aierelon to 85 85 to accomadate the collar? Will it make a difference?

If you have the bevelled collar that came with the UK unit then you shouldn't have to change cyclic or collective ranges. The bevelled side goes on the top and overall you should have the same range as before.

Only the first batch of UK swashes had this problem - they introduced the bevelled collar with 4 setscrews to fix it.

A split collar would be nice to save messing around with those baby setscrews - Quick UK are you listening !!

Its the collar that came with the swashplate, but at full negative it does bind

Set your cyclic ATV's so you have 6º of cyclic pitch, at 0º collective.

How do I know what 6 degrees of cyclic is, so 6 degrees is the amount to get that will result in no binds with full -9.5 pitch. I dont know if im ever going to be inverted at full pitch with full cyclic though, but definetly want it set up right.

Of course "we" do, but most of us mortals will find that 6º is plenty.

6 degrees is plenty cyclic deflection. The more cyclic deflection you have at 0 degrees, the more unstable and sensative the machine will be. At 6 degrees the machine is plenty stable, yet still performs very well. Just thought I would throw that in the mix. Yes you can run more, but at a cost. Not worth it to me.

Build it, fly it, crash it. Repeat as often as needed.

You might do if you needed to bail out in a hurry.

6 degrees is plenty and shouldn't bind

So how do you measure 6 degrees duh
Do i need a protractor?
Thanks for all the help Al

You set collective pitch to 0º. Don't move the collective from now on. Pitch gauge still on main blade, with blade over the nose and tailboom, give full aileron deflection in one direction, say right. Align the pitch gauge with the flybar, as you do when checking collective. Now go full deflection in the other direction,(left). Read the gauge again. One reading will be negative, the other positive. It's the numbers that matter. Now place the blades 90º to the tailboom, and do the same drill, only this time use full elevator, fore and aft. You want to choose a servo wheel/arm that will allow as close to 100% ATV's, while showing 6-7º of cyclic deflection. In the Raptor manual, they say to use 10.5mm servo arm dimension. That is very close to perfect. The aileron is sometimes off center(ie. the ATV's might be 88-110, or something like that. I prefer not to use SUB-TRIM to correct the off center. I use the HD servo wheels, and drill my own holes. One day, all servos will have adjustable centers, without effecting the ends. IMHO, this set-up makes for the nicest flying heli. Some decent paddles, and some EXPO makes for some smooth flying.
