AF models F-22 conversion to twin 90mm

AF models F-22 105mm converted to twin Freewing 90mm 1350kv fan on 8s per side. All internal ductwork was removed and replaced with Mylar for thrust tubes and new ply mounting was added after the old was removed for the new 90s. The vertical shown early in the video was 900' and I rolled it over as out ceiling at the field is 1200'. The all up weight of the model was just under 17lbs with Roaring Top 6250 mah 4s batteries, on 5000mah its 16.5. Flight times range between 4 and 5 plus minutes with throttle management.
