Making noise for the first time is a wonderful feeling. That fuel pressure sounds a bit high. Should be closer to 40. Is it properly calibrated? 3500-4000 rpm with a closed throttle!

I barely got it stopped in time. :) Ah ha! The rear (#2) rotor's injector wasn't firing. Someone has to say it, so I'll guess it might as well be me. The rotary was designed for 4 injectors, not 2. Loose one on take off and, well, we all know what can happen. The engine will run perfectly well on one set of injectors and one set of plugs, but I wouldn't dream of taking off with one of these systems not working. Am I missing something?
