This is my 4inch FPV Racer. Its build on Falcon Multitotors Garage Crab Platform, using Seth "PhreakinFPV's" Garage Crab Pod. It is an absolutely best to fly, durable, fast and easy to build. I would recommend if u get this FC to reinforce the USB port. And also the DAL 4045 x3 props are pretty good to try!.
