Notes on completing the model
• Before building the model it is important that you study the plan and read the instructions right
through to the end. Tools can be dangerous; be aware of the hazards involved in using them.
• Use cable of adequate cross-section, capable of carrying the currents which will flow when the
model is flying.
• Before making any glued joints, be sure to clean the surfaces and remove all traces of grease. We
recommend sanding lightly, or wiping with a non-greasy cleaning agent. The same applies to
surfaces to be painted, otherwise the paint is unlikely to adhere well. Before gluing parts to the
fuselage it is essential to roughen the surfaces with fine abrasive paper and de-grease them with
acetone or similar solvent, otherwise you will not obtain strong, durable joints. This applies in
particular to moulded GRP fuselages.

Radio control system
For this model you require at least a five-channel RC system with seven servos. The
transmitter should also feature a servo reverse facility.
We particularly recommend X-412 to mc-24 computer systems. The model is designed for standard-
size servos, e.g. C 4041, Order No. 3916.
We recommend the following receiver battery: SANYO AE-1400 AE, Order No. 2524, which should be
properly maintained before and after each flying session, i.e. the pack needs to be cycled (charged
and discharged) several times before it reaches full rated capacity.
For connecting the aileron servos to the receiver you will need suppressor filters, Order No. 1040. We
recommend that you pack the receiver and battery in protective padding such as foam rubber, Order
No. 1637.
