Picture this thing skimming just above the ground, either drifting through relaxed, flowy lines or getting thrown around hard in aggressive aerobatics. WUDFLY has built VENOM, a fully printed V-tail flying wing with a blended twin-motor layout, and it flies exactly as imagined, coming across as very stable and confidence-inspiring in the air.
It spans 600mm and comes in at 249g all up, right under the 250g line. The airframe is printed entirely in LW-PLA and accounts for roughly 110g of that total. Power comes from a pair of 1103 motors with a 2S 1000mAh LiHV pack, the camera is a DJI O4 Wide, and INAV runs the flight controller. Surfaces are elevons plus ruddervators on the V-tail.
Getting here took weeks of designing, printing and flight testing. The maker begins by deciding how the plane should fly, develops the wing geometry around established airfoil profiles, then simulates aerodynamics and investigates stability in OpenVSP and VSPAERO before committing to prints. Each iteration gets revised based on how real flights perform. The roll rate is set to 180 degrees per second in INAV, and the V-tail delivers enough yaw authority for coordinated turns.
The trade-off is endurance. Sporty flying gets 6 to 9 minutes per pack, which is on the short side if long sessions are your thing. At 249g there is also barely any margin below the weight limit, and any future hardware change could tip it over. Still, as a package this reads like a carefully engineered little plane.
