elombama,
aimaintenance is right, the right/down thrust is not overly important, but still will make a small difference in some planes, a large difference in others-mostly depends on how exacting the pilot wants to be. We experamented with a sturdy birdy, and went from 0 right/down to 5 degrees both ways, and everything in between, and it didn't make a huge difference. I did build a very light, big, boxy "camera plane" (high powered, light wing loading) and the right/down thrust was very important, especially the amount of DOWN thrust.

I highly doubt that your "right wing down, right turn on take off" is due to right thrust. You'd have to have 10 degrees or more for it to do that! Maybe you have a balance problem, wing twist, or even just out of trim.
Best to check all that before you fly again.
