Do either of you guys have "hover planes"?
I have some -tho frankly they are a passing fad to me.
The best of the bunch have:
A, 2-1 thrust ------------minimum
B, more length from prop to tail than wingspan.
CG? rearward location is helpful but NOT required.
My design critera for these models : You can never have too much power or a wing loading too low -
pretty well sums up the basics for a "hover" design.
The skill of hovering then is the same as learning to balance a basketball on one finger.
Some great "hover" flyers are not good aerobatic flyers --different ballgame.
Learning to fly a helicopter is a huge assist in seeing how this all comes together.
