Mark4 V3 Pro 13 Inch 570mm Carbon Fiber Frame Kit

The Mark4 V3 Pro 13-inch is a 570 mm wheelbase 3K carbon fibre frame kit for large long-range, cinematic and heavy freestyle FPV quads running 13-inch propellers. It takes standard 20×20 and 30.5×30.5 mm electronics and a 19 mm micro camera, so analog and digital video setups both fit.

• Flight controller/ESC stack and VTX mount on 20×20 or 30.5×30.5 mm hole patterns
• Side plates hold a 19 mm micro FPV camera
• Motor mounts drilled on a 30 mm spacing for M4 screws
• Kit includes plates, arms, standoffs, screws and nuts

Before ordering motors, check that their base uses a 30 mm M4 bolt pattern and that the maker rates them for 13-inch props on your chosen cell count; the 30.5×30.5 mount leaves room for the larger 4-in-1 ESCs these builds need.
