The F330 is a well thought out 330mm quad frame built from quality materials. The main frame is glass fiber while the arms are constructed from ultra durable polyamide nylon. Assembly is a simple and the frame features 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.
