model sits on the nosegear, no additional weight required for balance
main gear :CAUTION, it is highly recommended to reinforce the longitudinal bogie with 0,8mm steel wire, to support the weight of the model
engines: ADVISE remove the rear cover (which is required for the casting process only ) from the intake pieces. The diameter of the fans is slightly larger than the engine lips, hence insert the fans from the rear.
differences to the A300-600 are the engines (early CF6), tail cone and wings
