Jim,

down and right thrust are basically "trimming condition" adjustments. Some designs don't specifically mention right thrust (or down) but it doesn't mean that they couldn't use it. Basically I think you're going to have to find out in flight unless others who have built and flown one can point you to what angles they used and why. I hope this helps.

Do post some photos of your progress!

Phil,
