The Sig Kougar canopy is a custom fit for that kit. You can order it from Sig... but it will requir a turtledeck similar to the Kougar's.

You can go to the Sig website and order a bubble canopy... they have several sizes available. One of these can be cut down to fit almost any Pattern plane. The 9 inch, cut to 7 inches long is a good fit on a 40 inch span Mustang for example.

Then there's all the different shape plastic bottles... I cut a lot of canopies from 28 oz, 2 liter and 3 liter bottles. (some require a bit of heat forming...) The PET plastic of soda bottles is VERY durrable. [img]i/expressions/face-icon-small-smile.gif[/img]
