Fig. 32 - Checking the model's Balance
- Place the battery in its compartment without connecting.
- Mark the Centre of Gravity (CG) on both sides of the fuselage; the position
is shown in the photo.
- Support the model at the marked points and allow it to hang freely. When
correctly balanced the airplane will remain horizontal with the nose slightly
down.
- If necessary, adjust the position of the flight battery to achieve the correct
CG.
- Mark the battery location in the fuselage, so that you can be sure of
positioning it correctly after recharging.

- Pack scrap pieces of foam around the battery in its final position, otherwise
there is a danger of it shifting in flight and altering the model's balance.
- Charge the flight battery and the model is ready for flight.
