450 MM Quad Frame. The main frame is glass fiber while the arms are constructed from ultra durable polyamide nylon.
This version of the F450 features integrated PCB connections for direct soldering of your ESCs eliminates the need for a power distribution board or messy multi-connectors keeping your electronics layout very tidy.
F450 also comes with stronger molded arms, so no more arm breakage at the motor mount on a hard landing.
Assembly is a breeze with pre-threaded brass sleeves for all of the frame bolts, so no lock-nuts are required. It utilizes one size of bolt for the entire build, making the hardware very easy to keep in order and only requiring one size of hex wrench to assemble.
