About this Plan

Spook 72. Gull-wing old-timer IC free flight.

The Spook design dates back to 1940, it was originally a kit from Modelcraft. See Spook 72 (oz11046) for the closest plan we have to the original drawing.

This here is a modern plan redrawn in CAD, it shows RC installation for both 3 and 4 channel - with ailerons. Unknown author, no credit.

Update 04/04/2013: Resized this plan up to full-scale. That makes it a slightly impractical sheet size of 86in x 94in.

When I have made this Spook 72in [see more pics 003, 004], I have used a .25 glow engine but some time ago I have changed it by a brushless electric motor and it flies magnificent. All airplane is covered with silk. Thanks

This appears more like a scaled up Spook 48. The 72 has the window design shown in the photo

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
