You dont have to get this complicated....
Quicky 500's are a square box with a NACA 0012 airfoil and they do ~120+ with a .40!
But look how much faster the Formula 1 models go with the same engines....
Quickie is controlled by rules that limit the fuselage shape IIRC. Otherwise they'd be circular or oval and the engines would be cowled in.
