Plan file details

Trolleybus. Free flight power model. Quote: "A Prizetaking Power Duration Model with Low CLA, for 2.5 cc Engines. Trolleybus, by BR Newman. Fuselage. Commence by cutting out all formers from 1/8 in sheet (F1, 2A, 3A and B, and 4A from hard stock). Face those indicated with 1 mm ply and leave to set. Continue by cutting out fuselage top decking and master longeron from 1/8 in sheet and making gussets from scrap. Select a length of medium 1/2 x 1/4 in for the keel member and cut to correct length. Pin down and ensure that it is straight. Next, erect lower halves of the two-piece formers (except F2B) and also F7, 8 and 9, using a setsquare and the scrap gussets, which are lightly cemented in. When set, add the master longeron and cement on F5A and 6A. Now cut engine bearers to correct length and chamfer ends to give 10 degrees right thrust. Thread F1, 2A, 3A and 4A onto bearers and cement firmly. Make sure assembly is true and square, and then cement in position on top of the master longeron. Cement front part of fuselage decking firmly to the top of F3A, 4A and 5A, adding the 1/4 sq gusset to rear of F5A. When this small gusset is firm, remainder of decking may be cemented in place, the whole assembly removed from the board, and the soft block under the wing LE (marked B on plan) may be fixed in position..." Trolleybus, Model Aircraft, February 1955. Direct submission to Outerzone.
