Final work on the model involves fitting and gluing the navigation lights, hatch covers
and aerials.
Balancing the Jodel ROBIN DR 400/180
The completely equipped model, with the fueltank empty (or the flight battery
installed), should balance level at a point about 130 - 140 mm aft of the wing root
leading edge, ideally with the nose inclined slightly down. It is easier to balance the
Jodel when it is held inverted. If necessary, adjust the position of the receiver
batteries until the model balances at the stated point. Before flying the aircraft, set the
transmitter trims to centre and ensure that all the control surfaces are also exactly at
centre (neutral).
