Last Resort. Rubber competition model.
Quote: "Last Resort. A tried and tested open rubber model for pleasure or contest flying by well known modeller, Jim Baguley.
The 1956 season saw the arrival of the first version of this design, which was to be used as a reserve for a larger model but consistently outperformed it! The model seems to be viceless and easily trimmed and the several reproductions of it, built by fellow club members, have performed equally well.
The characteristic flight pattern on 900 turns (1,000 usual max) is a near vertical spiral for 150 ft, then gradually levelling out till the prop folds at approximately 350 - 400 ft after 70-80 se., when it should glide for a further 2:50 to 3:00 min giving a usual time of 4 min. This is, of course, with good rubber. If the rubber is weak, performance may be cut down to just over 3 min. in which case the motor should be increased to nine strands 32 in long, which will give almost equal performance.
It should be emphasised that the model is designed to climb steeply and fast, and should be allowed to do so otherwise performance will be killed. No trouble should be experienced in getting the airframe weight down to 2 oz; indeed, with care it can probably be got down to 1.5 oz, giving a total weight of 3.1 oz to 3.5 oz.
Fuselage. Use soft to medium balsa throughout and if you fly on a place like Chobham Common cover the fuselage with heavyweight Modelspan! The outside corners of the longerons should be radiused slightly. With the rubber motor fitted, the wing mount should be attached to the fuselage in such a position that the e.g. falls at the point indicated on the plan..."
