Roll trim

[PaulL]

My SQ2000 has a slight roll to the right - it may be due to engine torque, did not notice so much when coasting down to the runway.

 

Is there a common way to add roll trim to canards?

In a COZY MKIV, there is a manual roll trim, using springs and a handle. Many people have made modifications to electric trim systems as well. See:

for a view of the system.

It turns out the problem was the wing alignment. I added an extra washer to the right wing upper bolt. Now it tracks fine and I can simply use the auto-pilot for "roll-trim".
