I finally maidened my Flash with the Artes Falcon in it. I am trying to get it done for Florida Jets , it still needs paint (all white version),but I did get to fly it . The weather has been lousy here in the Northeast. I had problems starting the engine, it was 25 degrees F , very cold .After three time outs it finally lit off. It seems that the egt it very slow to come up to temp, like there isn't enough propane flow, I kept the propane bottle warm in my car then left it hooked up while starting but it still times out, The propane lights right away but ,the temp moves up very slow. I have plenty of flow out of the regulator valve on my propane bottle. I even tried to start it again after I got home in the warmth of my garage, But It still times out and refused to start??. Anyhow , the jet flew very nicely,but the engine flamed out on the third pass, Maybe it was an air bubble stuck somewhere . Luckily I was about 40-50 ft high and a made a complete circut around the field and landed, Oh yeah, forgot to tell you the landing gear wouldn't completely retract , had to land with the gear hanging out of the wing and nose. I belly landed it ,and there was no damage at all, the gear closed when it landed. I carried the jet back to the pits and cycled the gear and it worked normally?? Maybe the 25 degree weather had something to do with the gear. it might have froze in the cylinders or air tanks ,or valves. Overall I am happy, now I can get the paint work done, and try and get the engine bugs worked out.
Couple of items I'd suggest you look at... had the same issues myself. Go into the ECU of the Falcon (Start Menu) and boost the gas flow. Some guys leave the propane bottle hooked up to the engine and squeeze the trigger during preheat to get the temps up. Also, check to make sure the temp probe is sticking through the exhaust cone far enough to get a good temp reading. I had one engine where the tip was flush with the cone and it couldn't get a good temp reading.
Make sure the nose gear retracts cleanly without hanging up. If it twists slightly and hangs up, and you are using the stock valve, the whole system gets screwed up. The most common problem with these nose gear is that the steering line causes the gear to twist while retracting, and the strut hangs on the former just ahead of the wheel.
congrats on the maiden.
