That is just mental.
So - is that just a Bell Rocket belt with the nozzles on the foot platform instead?
I assume from the sound and instant thrust it's rocket powered and not turbine?
Or are those model aircraft turbines at the side?
The exhaust efflux also looks turbine like - confused.
Personally if flying the damn thing I'd be zoom climbing out of the dead man's curve asap on take off!
Where's his ballistic parachute??!!
That Monaco video sure sounds like a model aircraft turbine.
