Balancing a large model airplane
I had trouble trying to balance a large model, Sbach342 190cm wingspan by myself.
I cut 2 pieces of 3 mm ply from some scrap, cut 2 pieces of tubing, 5mm od and glued them to the ply pieces .
Taped these new "balancers to the wing, underneath, with masking tape with the tubing at the indicated cg.
Placed the model on two chairs so that the tubing could "roll" freely and voilĂ*...done.
See attached pics.
