Well, interesting idea.
A couple of things to remember though. Anything that collides with a helicopter will win. Being mostly around airplanes and lately more around helicopters, I have found that one of best things to have is a lot of room. Building a tin-shed style hangar is not that expensive compared to repairing a helicopter. You would need to have sideways guides that starts quite a few metres in front of the container (sorry, hangar
), that sort of takes away the portability. Will there be a need for a ramp to get the helicopter inside? If so, will the front blade protrude higher when on the ramp? If the hydraulic cart breaks down, will there be enough room to put on a pair of wheels and gently push it out? Will there be sufficient room to open a door when inside, otherwise it's a bummer to forget the wallet inside. If the weather isn't great, it's always nice to have some room to do most of the daily when still inside.
Just my thoughts. Good luck!
