Swaid,

All the fuel lines, etc, are up to normal aviation standards and beyond. As we speak, I've had A&P's crawling over and through the plane for about 6 weeks, making sure that everything is up to snuff. We've changed a few hose clamps, changed from rubber to silicone coolant hose, and done a few other odds and ends. They haven't found anything that would have been a safety of flight issue in their eyes. Basically it's been new professional eyes doing the button-up, since I don't have time to do all of it, and I wanted professionals with L-IV-P experience at this stage.

The engine is the American Eagle V8. It's an upright 540 CID Donovan block, with the goodies I've mentioned before. The Eagle group was a set of Lancair builders/drivers that went down the same logical road I did. They put millions into the development process, and I think largely they did a good job. The required airframe mods were done by a professional airframe engineer, formerly of Boeing, now with another aviation company.

We've been a bit paranoid, putting silicone rubber pads almost everywhere there could conceivably be a vibration and chafing problem. We've built stainless heat shields, and added Zetex at potentially hot corners of aluminum intercoolers.

Today we had a full-power 5 minute ground run without difficulties. Gearbox and oil temps were low, with water sprayed over the radiator because of the static condition (low airflow due to zero airspeed).

Have I missed something? Testing will tell, and that will progress carefully. We had anticipated test flying this week, but that's being delayed by little nuisance bumps in the road. I won't rush it.

Ted,
I am an aircraft accident investigator. The majority of all reported "engine failures"  are too much air and not enough fuel.
Best Regards,
Jeff

-----That's painfully funny. ROG isn't much fun, and the reasons for it are most often, I suspect, pilot error, not airframe and powerplant.

Set,

I'll get some pix up. Today I documented the engine run with video.

Jeff,

I'm not ignoring anything they say. And I am a firm believer in the 180-degree turn, unlike many doctors. I'm painfully aware of my limitations.
