The DJI Innovations F550 Flame Wheel frames are built from very strong materials, the arms are made from the ultra strong PA66+30GF material which provides better resistance to damage on hard landings. The main frame plates use a high strength compound PCB material, which makes wiring of ESCs and battery very easy and safer on the lower of the two frame plates which is also the power distribution board. The overall frame design allows enough space when assembled to fit an autopilot systems between the top and bottom plates of the Flame Wheel. The arms supplied in the kit are different colours, 2 red and 2 white to allow for improved visual orientation in flight, other coloured arms in black are available.

These frames are very easy to build and are held together by a set of shouldered bolts, the bolts pass through the predrilled holes in the top and bottom frame plates of the F550 Flame wheel frame into the top and bottom of the arms, a total of 6 bolts per arm holds the frame plates in place and ensures that the F550 Flame Wheel frame is very solid, and are able to put up with a great deal of use or abuse!
