250 size FPV racing quad

thingiverse

I've been flying these for over a year and whilst the market is now flooded with these racing quads, I figured it might still be an attractive option to anybody who wants an easy route into the game with an airframe that can be easily repaired with home-printed components! The airframe is light and pretty agile (even on 3S!) if you keep the components down. The offset motor positions are similar to a well known and popular 450 size quad - they reduce yaw rate but induce some pitch at the same time as roll (or something like that). Seems to work well enough. The frame is robust but designed to break in a hard crash - having said that, it has survived 20ft drops, cartwheels across fields, and even full-throttle smashes into an antique millstone (don't ask!) The arms can be replaced in minutes in the event of a crash and the multi-part design gives more options for customisation. Go nuts!
