Notes on building the model
•
Before you start building the aircraft it is essential to read right through the in-
structions.
•
Please bear in mind the dangers inherent in the handling of tools.
•
When preparing the wiring, be sure to use cable capable of carrying the currents
likely to flow when the model is flying.
•
Deploy the receiver aerial as far away as possible from high-current cables (at
least 3 cm).
•
Remove all traces of grease from the joint surfaces of components which are to
be glued. A good method is to sand lightly before wiping with a non-greasy liquid
detergent solution. The same applies to surfaces which are to be painted,
otherwise the paint will not adhere permanently. Before gluing any GRP parts,
and GRP fuselages in particular, the joint surfaces must be sanded thoroughly
using fine-grit abrasive paper before de-greasing with a solvent such as acetone.
This is the only method of obtaining durable glued joints involving GRP parts.

Radio control system
The RC system must feature at least six control functions and eight servos; the
transmitter should also include a servo reverse facility.
We particularly recommend mc-22S to mc-24 computer systems. The model is
designed for standard-sized servos.
We recommend the following receiver battery: 2/2500 7.4 V G 3.5 20C LiPo,
Order No. 7633.2, which needs to be maintained carefully before and after each
flying session. As ON / OFF switch for the receiving system we recommend the PRX-
3A, Order No. 4135.
