"Bipie" - Profile depron biplane cartoon style


Hi guys, have been a bit lazy the past few months cause I restricted myself on just reading those interesting threads in this forum and letting them inspire me for new projects.
Time to give something back I think. So here is what I was designing a few time ago and finally managed to start the build....

The "Bipie" is designed for low wing loading and some nice and relaxed low speed flying, hence the bipe configuration. It will have rudder, elevaror and aileron control so I may be able to use it also as a moderate 3d trainer.

here come some pics of how I put everything together....

Very COOL and FUN !!!!! One suggestion , the intersection of two lines at a sharp angle (bottom of fuselage aft of the canopy )gives worries to stress, and breakage ...a slight rounding of the intersection relieves such stresses, providing the plane doesn't break somewhere else ...hahahaa

Thanks everyone for your positive feedback and the tips.

I use two styrofoam pieces ("styrodur" to be more precize, that is the light blue stuff) of about 2cm of thickness and glue them along the fuselage. That increases stability of the overall construction and allows the use of two more struts to support the upper wing. These struts are reinforced with bamboo skewers on the leading edges and attach pretty nicely to the styrofoam. I wanted it to be rather solid in anticipation of some harder landings I produce on a regular basis.

Here we go with some more photos as the build progresses...
