Here are my calculated comparison of classic takeoff with very powerful launchers. No hope by this means
Rotor inertia: 190 kg.m2
Static Propeller Boost: 2400 N decreasing to 2100 N at 45 mph
Coefficient of rolling in the grass: 4%
Area of parasitic drag: 7 sq.ft
Induced drag corrected by ground effect
