When this thing is up and flying, it covers a huge range for its size. The maker has built a 600 mm twin-motor flying wing that can float along near its 21 km/h stall speed and then be pushed to around 110 km/h for fast runs close to the ground. All of that comes in at roughly 215 grams, which is a remarkably light airframe for a twin. In my view that slow-to-fast spread is the most interesting thing about the design, since few wings this small claim both ends.
The construction approach stands out. The airframe is printed in LW-PLA or PETG, and assembly relies on M3 nylon screws plus clip-on brackets along the leading edge. Both the wings and the motor mounts come off, so a damaged panel or a swapped motor mount does not mean rebuilding the whole plane. The battery sits under a magnetic hatch held with a Velcro strap, which looks like a quick field swap done neatly.
The electronics list is tidy: twin 1003 14800KV motors on a 20A Flywoo ESC and an F4 Mini flight controller running INAV, with two 4.3-gram servos driving the elevons. Power comes from 750 mAh or 1000 mAh 2S LiPo packs.
One trade-off worth noting is endurance: flights run 5 to 10 minutes depending on the pack. Testing so far has happened over grass fields, which seems a sensible surface for a light printed wing. I would love to hear how the airframe holds up long term, since nothing has been said about durability beyond those field sessions.
