About this Plan

Chippy. Radio control sport model. WIngspan 52 in, for 40 - 48 2-stroke engine and 4 channel RC.

Quote: "A super 'scale-ish' aerobatic model for the sports flyer. Chippy started life as a combination of ideas in a telephone conversation between myself and the Editor. We decided that the model would have to fly like the average club Wot Not, be just as rugged and easy to build, but look like a real aeroplane. I have always liked Chipmunks, especially the Krier and the Super Chipmunks and after putting the suggestion across we decided that was the way to go.

The next day at work I spent my lunch time making a sketch of the proposed design and duly faxed it of to Peter (the 'Ed') for approval. The go ahead was given and the next two weeks were spent drawing the plans and constructing the two prototypes.

Construction: Start by cutting a kit of parts out; selecting your wood carefully, hard for the tailplane soft for the rest.

Fuselage: Make two fuselage sides (left and right remember) by installing the triangle stock and formers 2 and 3. Cut slots in the triangle stock and the fuselage sides with a razor saw where required to assist a natural curve to the fuselage. When happy stick the two sides together checking for accuracy as you go. Tack glue F1 to one side of the fuselage, then measure and mark the centre of all three formers. Push a pin into the marks and use these pins as a guide whilst bringing the front and back of the fuselage together (looking from the rear you can see that the fuz is straight if all three pins line up). Install the ply ring at front then reinforce the slots in the triangle and sides with glue, install the servo tray and your ready for the top and bottom.

Glue the top and bottom onto the triangle stock (no point gluing to fuz sides as these bits will be planed off). Next comes the messy bit, start planing along the fuselage sides at 45 deg. Until you see about 3/8 in of the triangle exposed. Now start planing either side to form the rounded effect and round off the front..."
