Lets actually accept it that people are unrealistic overpowering their Jet/Helis that a Typhoon is howering in a charm, only F-35 and later planes could do.
The kind of power-luxury a R/C builder enjoys, would be a sheer envy to any real plane/Heli designer (team).
The Heli is fantastic and highly detailed not only in cosmetic design but flight characteristic and power.
And Vinay, R/C people are making Fly completly flat wing made of Depron/Coro and inverting even Flying Box/House and what not. hardly 1% or real world helis can do inverted flight, leave alone 3D. Real Heli do take time to reach head speed for lift off as they dont run on EP/Outrunners
Bow Down to this Heli builder and Pilot!
