How do I balance my Eraser / Warbird?
Get a couple of pencils, or drumsticks and tape them to a chair with the points sticking up about 6 – 12inches apart (not critical) and at same height (critical). Balance the plane on the points (at left wing spar on one, right wing spar on other) and see which way the plane falls (forwards or backwards). Adjust nose weight until plane hangs nicely (Eraser) or stays momentarily balanced (Warbird).
