Thanx much, Bob. I see it now; just more lever on the tail while
still measuring up front. I wonder also if one could place blue foam
pieces on top of white engine mount and solid places of the Rotax.
Fiberboard on top, then barbell weights, electric motor, old car
battery, frozen turkey, a little fixed boost on the tail. That way
not coordinating 2 people, yanking down on prop, swinging needle or
flopping digits on scale, w/o able to see exactly when bungee stretch
commences w/o third person?
