I've met them and I'm impressed. Top flight team with some very senior industry experts and execs. I share concersn about power-to-weight, noise and the old issue of pressure seals. Prepared to suspend those concenrs and see what happens. Kit is the plan and they claim to have sales ready to fulfil. HV enhancemment a function of rotor momentum. They claim much easier to fly in absence of torque coupling and videos show pretty impressive rate of climb on pulling torque.
Pegaus IPOd on the London Plus (Ofex) market recently, so fair capital base. Hope they succeed.
