For a given engine, what`s better:


a) Smaller plane to have relatively more prop wash over surfaces, more giroscopic effect and more power to weight (more weight and wingloading too)

b) Bigger plane to have the lowest wing loading and float along (less prop disc, less power to pull out)


I know that there might be a sweet spot but I want to know your experience to lean on one side or another, I have have used the B concept on this plane, 3D`s very well but lost airframe due a structure failure, now i`m on the rebith of it (pic1)
On the other hand the riciculous big prop on electrics makes hovering super easy (pic2)
