Hi Scott,

Thanks for the input.  I'd like to see your set up some day.  My aileron
trim works of course, but I think that there is some slippage in the capstan
and string as has been thrashed around before as a topic, and the spring
tension with the kit supplied springs that were disgarded to one more
appropriate to specific need...and that's before we talk about where the
roll servo gets into the act for full throw etc etc..

I am happy enuf with my aileron system, control surface final throw, and
trim mechanism, and would not want to get into that as a topic.  

I only made the point for others.  It was not a req for help. I am used to a
yoke where aileron displacement on the takeoff roll is very obvious.   

Regards,
Terry

Terry,

I wonder why you have the friction?  I'm sure you've looked but, it 
doesn't seem right to me.

My stick will stay somewhat but thats the trim system returning the 
stick to whatever trim position I have set. Is that what you mean?

One of my before takeoff checks is trim, elevator and aileron.  I 
visually look at the elevator for elevator trim(its right in front of 
us) and wiggle the stick to verify it returns close the the middle...

When first flying my V I would tend to take off with left banking 
aileron and would drop the left wing a bit when the mains left the 
ground.  I fixed that by glancing down at my hand  during the roll to 
verify I had neutral aileron. After 3 or 4 takeoffs I didn't need to 
look anymore.  Assuming I was taking off with no cross wind of course.
