When started to invade his neighbors in 1939, was not quite ready. had the Morane-Saulnier M.S.406, which was at that time the most numerous fighters in the French Air Force, but not a match to the BF-109E. The Dewoitine D.520 was starting to come out in small numbers and was getting closer to the BF-109E with better speed and tighter turns. The Bloch MB.15x series was slowly coming out with a single squadron getting their airplanes, mostly lacking parts.
And then Arsenal, a small, nationalized study firm was working on a very promising little fighter; the VG3x series. A few motors were explored like the Merlin, now reserved to the British airplane production, the far away Allison engine and the local Hispano-Suiza company with their 12 cylinders Y inline engine allowing for a 20mm canon shooting through the spinner. Already performing better than the D.520, the VG.33 had a less powerful motor version.
By the time was at war, less than 20 VG.33 were delivered, with only 2 being operational.
This 800mm wingspan rendition is based on the initial modeling work from Maxime Daout and is powered by a 2507 or the more common 2212 outrunner and is designed to be printed in mostly LW-PLA, with a key parts in PLA+, like the core fuselage and wings sections, motor mount, spinner, servo and battery tray and spinner. The design has carefully planned internal structures for LW-PLA slicing resulting in clean parts with minimal oozing.
