I guess I really should say that the finished product will be flown by autopilot, although initial testing will be done in manual mode at a reduced weight.
Currently it is running a .71 OS 4 stroke modified to run gasoline. I am just wondering if we can go any smaller.
That is my calc sheet. All the non-bolded variables were just to help my calculate the wing area (I suck at geometry). I wish I could upload the document so you could see the formulas, but it is all pretty standard.
I followed the formulas in this document to calculate the stall speed:

We really cannot have landing gear. Hand launch or water balloon launch is the only thing we can do.
