Sean: Any chance of Water contamination, From Condensation?
Not a chance. The fact is, when I go to a jet rally, I usually haul 6 jets, 60 gallons of fuel, spare engines, asseccories, etc. All four of my Artes Engines failed at the Waco Jet rally in one form or another. For now, I am taking the blame for this at least until my engines are placed in a micrometer. Two of my engine failures were on startup, and two were in the air. The failures in the air were almost certainly due to a too agressive pump setting for that particularly HOT day!
The other two failures were almost certainly due to too much propane during startup.
At first there was a suggestion that there was a fuel problem.
This can not be, the same fuel was flown 15 gallons through a P-200 same weekend, and about 5 gallons through a P-70 same weekend, and about a gallon through a P-120. Before my Rhino quit in flight, I had 10-15 gallons through it the first few days of the Rally (Tuesday through Friday).
A friend of mine loaned me a P-70 for my F-86 and I flew that no problems.
These Artes engines are good engines, no doubt about it, I have 500 flights on them easy. The tolerances on them are tighter than other manufacturers which gives you more thrust for the same size engine than say jetcat. However, you run into potentially more problems over time than jetcat.
It's like the difference between a Ford Taurus and a 67 corvette. Which is faster, but which is more reliable does not require working on maint, or taking care of issues on the weekend.
I'm sure Artes is working on getting to worry free engine performance over time. I'm not worried about any of this at all.
When four engines go out for one reason or another, that's something, when it is all under the operation of ONE GUY? I become the suspect, and I don't blame anyone for feeling this way.
We will know here in a couple of weeks for sure.
