Yesterday I received issue 30 of Make Magazine, and on the cover of the magazine there was a big "RC Stunt Plane".
It seems a super-cheap platform on which building a frame for testing arduplane on: the frame is basically extruded polystyrene insulation board with a reinforced area to host all electronics and motor.
For those who haven't received the issue yet, here is the link to the page with the step by step instructions: http://makeprojects.com/Project/-The-Towel-R-C-Stunt-Plane/2042/1
This project has been developed by the The Brooklyn Aerodrome rc plane club, and besides the tutorial on MakeProjects you can look on their site a lot of other video tutorials, and see the updated part list.
Personally, now that I have 2 APM (v1 and v2) I could use the old one to build a plane, and I was wondering if that frame was good enough for using with the ardupilot or was too open for hosting it.
But I'll try collect some spare parts I have and see if I can make it fly: only big problem is that in Europe house are built "properly" :) , so that kind of polystyrene will be pretty difficult to find around.
But I'll try and see if I can keep you updated with fitting the APM on this frame.
