Foam Hovercraft

This is a fun project in parallel with my 250 gram plank. It's constructed the same way (hot wire cut pink xps foam), powered by the same 1407s and 3052 props (two instead of one) and weighs 275 grams.

You must have a laser cutter as well judging by the way the ply is cut. Cool hovercraft, you should sell it as a kit. I am also curious as to how it rips around

Yeah. But since most of the laser cutting goes into building the jigs, it's kinda silly to buy or build them to just build one hovercraft. It would be suited to a class or makerspace environment where people can share the tooling.

I haven't posted a video because most of the video would be me driving into things and I'd be embarrassed. It's extremely high performance; its thrust:weight is >>1 on 3s, and there is no limit on its yaw rate. With full throttle and full thrust vectoring it spins like a top. I would assume on a large flat surface it would achieve similar speeds to 250 gram wings; it has similar weight, thrust, etc. However, due either to the skirt being badly constructed or lift fan torque, it has a yaw bias when fully hovering, and due to its cg being aft of center (no room with lift fan there) it kinda slides backwards. Keeping it still requires effort. Its poor handling isn't really a problem for me, though, since one of its main purposes is to practice driving vehicles that handle poorly.
