Gary,
As always you are giving good advice.
I haven't flown my UCD yet...in fact I haven't flown anything in 20+ years!
[X(]
I am just trying to figure out if my plane is built differently than everyone elses or if the up/down thrust isn't critical if nobody else is having to correct it.
I think I will leave the 2 washers in place that I have for right and down thrust and see what happens in a couple weeks.
Thanks again!
JLK
