You misunderstand the RC hobby. My brother was into RC boats, cars, airplanes. Fixing the damage is part of the “fun”. I once watched one of his gas-powered boats lose radio control, end up in the bull rushes, with the engine going faster and faster until poof it stopped and emitted a puff of smoke.
(I was hoping they’d demoed the operation of the control surfaces.)
Big scale r/c can be incredibly convincing and mistaken for full scale when done up right and flown “realistically”. Pretty much ever since 2001’s Pearl Harbor and 2004’s The Aviator, more and more the film industry SFX crowd have been moving back to practical effects which include employing large scale a/c. Smart move.
yes - if you are familiar with the hobby you are used to seeing piston driven ducted fans, even electric ducted fans these days but not for such large models. But actual turbine engines - wow.
