My second one weighs 8lbs even with YS 91ac using my wal mart electronic fish scale. How much right and/or down thrust is anyone using? With 2 small washers giving rt thrust, plane wants to pull left a little on long uplines, also when hovering and go to full throttle, wants to pull to canopy slightly, thought I might try some down thrust, and also try to get the cg back some more by moving the battery to the rear of the fuse
