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
