Yes cool idea, anything I should know to reproduce this one on a bigger scale with electric power?

This planform is a fairly old design of mine. I built several RC versions of it last year. You can see the build log for it here: http://www.rcgroups.com/forums/showthread.php?t=1484974
The basic plan is fairly simple. Just choose a wing span and chord you want to build at. Then extend the tips by about 1/2 to 2/3 chord length. The tip width is roughly the same as chord length but can be modified a bit larger or smaller if necessary.
Cut out the shape (or draw out the plan) using the above measurements and give the 'tail' a bit of reflex/up trim. CG as usual is around 1/3 chord but my RC models prefer very nose heavy CG at around 10% chord. I guess it depends on the airfoil of the main wing.
My RC version is very steady in the roll and yaw axis but is very pitch sensitive.
