After my recent purchases of secondhand engines and the repair of some fire damaged engines, I decided that I needed a test airframe that would be easy to build, and light and easy to fly. Those who have been in the hobby awhile would know that this would mean a Stick! This is an easy to build aircraft that has a large hatch on top for the fuel tank and a flat firewall with no cowl for easy engine access. The airframe is not C of G critical so engine weight could vary a bit without too much of a problem. I found that when I have changed engines on airframes, especially when changing from a 2-stroke to a 4-stroke, the change in tank positions and throttle linkages quickly results in a firewall that looks like a Swiss cheese full of holes! I needed to test engines from 25 to 45 cc so a 2 metre Stick with a fully built up fuselage was drawn up. The wings are foam and the control surfaces are sheet with strip wood added. I decided to add flaps and tip plates to improve the slow flight performance. I made the fuselage wider and deeper so that the firewall could accommodate a hole cut out to the diameter of a Super Tigre mount, so that the nuts and bolts for the engine mounts would not interfere when the dummy firewall was mounted to the main firewall.
