Phil, Thanks for the PDF.
Have you thought about what battery to use? I put the Tucano into Motocalc and it looks like a 3 cell 2200mAh LiPo will provide about 10 minutes on 70% throttle. With a 10x6 prop it will draw about 30A with the motor I intend to use (Powerpro 2820-5 1150kv - roughly equiv. to the AXI 2820).
Assuming an airframe weight of 750 gram all up weight will be 1100 gram. Max trust is 1250 gram, so vertical climb out should be ok.
