Construction of a Trainer


The subject of actual construction of a trainer is far too involved and lengthy to be covered in depth here. The trainer that the beginner chooses should have a good set of plans and step by step instructions that guide the complete assembly of the trainer including the installation of the radio system. There are many books and articles on this subject that are excellent sources of information. A beginner who has no experience in building balsa models should seek help from an experienced builder to avoid the mistakes that can have disastrous effects.

A beginner should consider using a strong, slow curing adhesive to allow time to correct mistakes during construction. One of the best is an aliphatic resin called Titebond. This cures slowly but yields an exceptionally strong joint and it sands easily after curing. All joints that are subjected to high stresses such as the firewall and center wing joint should be joined with a slow cure epoxy.

The main thing that a beginner must be careful with is the alignment of the wings. Wing alignment is critical in the flight performance and stability of the trainer. The kit's building manual should give detailed instructions as to how this is accomplished and special care should be taken to follow these instructions.
