So it's just like a.....There is only one active cockpit.
Kevlar and Carbon Fiber can support a lot of weight. I have been in the R/C hobby for over 40 years, I use Kevlar and CF on structural weak points and if there is a crash the Kevlar and CF never break its the surrounding structure that breaks.I would like to know what they used for that center “wing” section. It must be some of the strongest stuff around to be able to support payload and contain the thrust of all those engines.
