TQ250 racing drone quad V2

This is an altered version of my previous design, to enable the drone carrying a bigger camera on the top deck and accommodating a mini FPV cam on the lower deck. Reusing the robust design of the first version, easily replaceable arms in case of high speed/impact accidents :). Also reinforced landing legs, and all optimized for small printers to easy print...
