/diy/ - Do It Yourself

Hey all,

I'm completely new to RC and /diy/, and have been thinking of buying a model plane for a few months now, drew some plans etc and now wondering if I should buy the parts and try to build it.

Pic related is a poor CAD drawing without measurements. It's a biplane with about 120cm wingspan and a 10c10cm fuselage, but I may scale it down a bit (it otherwise may become too heavy).
I was thinking of building it from 5mm foamboard, and adding a really cheap chinese motor/ESC/receiver, plus an arduino/IMU to add my own PID stabiliser.
What I'm mostly wondering if wether the ailerons have enough size, and if the tail is not too short for horizontal stability.
Also, I didn't add a horizontal control plane because I flew someone else's biplane once and was told the wing struts add enough horizontal stability and roll-induced-yaw.

Would you think this basic design would fly?
