A possibly nice way to set belt tension (on a Trex). Assemble the heli, with the belt reasonably tight (as per the insdtructions). Then, loosen the stay screws (top of horizontal stab) and the four screws holding the tail boom into the chassis. The boom will move into the chassis due to tension in the belt. Tighten up the screws.

Belt tension will now be beautifully low, easily allowing spinning the main rotor (using the one-way) by turning the tail rotor, yet tight enough not to skip teeth.
