34 reactions · 14 shares | A typical engine test for the JetQuad - set your volume setting to high! We ignite all engines to idle and then wiggle the thrust vectors to make sure there’s smooth motion under heat load. The flames during start up look sweet, but they indicate a poor start - engine is dumping too much fuel during ignition. A bit more fine tuning, otherwise this beast is ready for the air! #drone #dronedelivery #droneinstagram #dronephotography #dronelife | FusionFlight | Facebook
