Very cool! I should really prototype my U2 with that type of construction, then move on to the more curvy construction. It's been stalled out too long!Half of the good flying is based on the plane. The wing span is 34". And it has only six parts to cut out. Change it up to a motor/prop and add landing gear and this is what you get. A very stable STOL when you also add my design of end plates and go for it. The trees are over 100+ft and I am sure I could fly within the bounds of just the parking lot and do steep landings. As you can see, pull the nose up steeper and it drops more, push towards level and with practice you can land it anywhere. More you practice, better you get. Good practice for sensing EDF landings.
I use a E flite 1360 kv motor with a 9x3/8SF prop and with the landing gear, gives you something else to do rather than bore holes in the sky.
Plans are available at RCGroups (label is Allycat) and if you adapt to your build material, you can have a fun time. Will help guide you on your questions if any..
Cheers!
