Look at the YouTube video where the girl gets blown by the jet blast.....
Folks, I work with these aircraft, it is NOT a toy.
At throttle up, and rolling, that force is pushing at pretty much max to get the beast to go in the right direction.....
Its like you have a high pressure nozzle on your hose.
If you hold it steady and aim at a target, that is max force, if you are using the same water pressure, volume, etc, but now run forward, away from that target, the force is only max, on that stationary target, for a mere second.
Guess what is going to give in first?
