There's nothing "speculative" about aerodynamics that can be voted away. I've flown "underpowered overweight" C172s in ground effect during soft field takeoffs and I've also flown scale 76" overpowered .60 J3 cubs and other scale planes in ground effect. The aerodynamics are the same. Its just how we get there that's different. As RC pilots the more one attempts more scale like takeoffs and landings the more you will come into contact with ground effect.
