The old Stryker could carry a lot of extra weight! I've strapped cameras on the nose, the wing tips, the rudders, the side of the fuselage, and flew it as if nothing was added.... Today's FPV equipment is very small so that won't be a problem. Flying a FPV aircraft at 90MPH could be very interesting though
Also, launching by yourself could be tricky, and sure enough, you need a lot of landing space (unless you land it Quique style...). Sure enough, I would not use a Stryker as my first FPV plane!
