Chipmunk (oz7550)

About this Plan

Chipmunk. Control line stunt model. For .35 or .40 power. Later kitted by SIG.

Quote: "Tremendous combination of good looks and flying qualities is best way to describe this month's control line entry. A semi-scale stunter of the world famous full scale aerobatic plane adds important eye points to the flying points for the serious stunt competitor. By Jim Van Loo.

Not very often do we have the opportunity to find a real airplane that has all the things needed to make it a fine stunt ship. Hal Crier's Chipmunk meets these needs, with good looks, a beautiful paint job and good moments.

I had decided to build a Chipmunk sometime ago since we had one based a few miles from my home. Unfortunately however. it was gone by the time I got around to framing one. Flying Magazine ran an article on Hal's plane and darned if old Walt didn't turn up with a scale three-view of the De Havil-land Chipmunk in MAN.

Chipmunk #1 was built with the standard De Havilland tail since I liked the wider surface. Number two was then built and is the one presented here. On #2. I tried to come as close as possible to copying Hal's model. The only area of difference is the wheel pants hook up. Sig Manufacturing of Monte-zuma. Iowa is kitting it and it should be available at the same time this article is published.

The canopy can be purchased from Sig and although I am not sure at this time I think that the kit will have a pressed butyrate cowl and pants..How about that, no more carving' Be very careful when selecting your balsa. Sig contest balsa was used throughout for models #1 and 2.

Construction. I usually start with the wing and there are three ways in which to build it: 1. Buy a kit, 2. Purchase a foam wing from Foam Flite in Mankato. Minnesota, or 3. cut, sand, and fit method, which I use. However, now that the kit is available. I'm finished cutting. The following is a suggested method to construct the wing. But if you are like me, you'll probably do it your own way and when everything esle fails, follow instructions..."
