Help - Down and right thrust amount?
Hello, I am electrifying a 100" glider. This is a floater and has a lot of wing area. I am mating the wing and tail group from one glider with a new fiberglass fuse from another. I am going to run a brushed 3.3 - 1 gear drive can with a 14" folder on 7 & 8 cell 3300 sub-c packs I have on hand. When I mount the motor how much right and down thrust do I need to factor into it? Would it be controlable without right and down thrust? I appreciate the help with this one, I could guess but would rather get it right the first time.

RE: Help - Down and right thrust amount?
Most planes seem to have about 3 degrees down and 3 degrees right to compensate for the torque.
I would start there and adjust if you need to but it should be controlable either way.

Actually, I've generally not seen more than 1-2 degrees of either in most planes.
Down and right thrust is a guessing game, and a matter of personal taste. You add or remove down/right thrust until the plane flies the way you think it should fly.
There should be no problems controlling the plane. In typical cases, the plane will simply have a tendency to climb under power, and a much less pronounced tendency to roll to the left under the same power.
