I built my first version of a DR-1 Cartoon Tripe in the Summer of 2010. The goal was a really really low wing loading, which came in at about 0.65 oz/sq.ft.
Fuselage is 6mm Depron, wings are 3mm Depron, covering is RA Microlite, propulsion is BSD 7mm gearbox, battery is 60mAh or 90mAh, RX is ZTRON 900mhz, and servos are Falcon Femto. Wing span is 16 inches and final weight came in about 26g. Thread is here
and also contains plans.
