In 19. why do you say to turn the motor in REVERSE and not in its normal direction ( I presume you mean by rotating the rotor blades ) ?
1. The CA gel is much lighter weight, and stronger, for the same weight [i.e., for the same strength, the shrink insulation must be thicker & heavier].
2. Inverting the heli simulates the rotor lift and puts the gears, etc., in flight position, in which the gear-teeth push from the "front" wall of the pinion's gear-teeth to the "rear" wall of the main gear's teeth. Rotating in reverse simulates the motor's force on the rotor gears [Isaac Newton] > gears are designed for one direction of rotation: try this and you'll find a difference in resistance to turning .... and only ONE direction is used for flight.
