Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). 1/8th speed (15fps) and improved video performance because somehow Youtube cropped the last frames of the other videos (?) I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

➡️ This video showcases the exceptional aerodynamic and hydrodynamic efficiency of the iFLY RAZZOR Pro in ultra-light wind conditions. ➡️ iFLY achieves stable flight and high speeds where most foiling craft remain stuck in displacement mode. Taking off in light wind is not inherently difficult per se. Even low-tech boats can lift off with sufficiently large sails and oversized foils. The true engineering challenge lies in combining early takeoff with high speed, superior flight stability, and precise control — and maintaining this performance consistently across a wide wind range. The iFLY RAZZOR Pro meets these demanding criteria through: ➡️ Active foil control system FlySafe® ➡️ Advanced foil design and construction — on a technological level comparable to SailGP, TF35 and America’s Cup foils ➡️ Mainfoil Differential T-Foil (MDT) — increasing righting moment by actively using the windward foil for downforce. The mainsheet stays tight, using the windward foil to create downforce Unlike conventional designs that rely on brute-force sail area and oversized foil area to get airborne — often at the cost of speed and control — the iFLY RAZZOR Pro maintains efficiency across the full wind range — from light breeze to strong winds over 25 knots and rough sea states.
