Incidentally I was surprised at the low current draw in all circumstances. At 60 mph and full surface deflection (w/o tabs) the current was 1/3 of stall current.

Not having a way to make simple in air measurements is a pain.

Dirtybird’s web site with many current vs. torque plots indicates torque is linear to current for most purposes between 10 and 85% of stall current.
