Loki the SubSonex Jet is a Free Bird!

My ever-vigilant neighbor caught the official end to my Phase 1 test period on "Loki," the little jet, this morning as I made a pass to "check altimeter calibration" (that's my story, and I'm sticking to it...) and then pulled up for the landing pattern. With that pass, I finished the prescribed 40 hour test period, but had actually completed the test program about ten hours before - yet these are still experimental aircraft and there are things I'll be looking in to, and will be collecting data for some time to come. Officially however, the airplane is now free to roam outside of the original test area (which was admittedly pretty large) and can be taken anywhere... like Southern California, or even Wisconsin!

Thirty Hours

Selfies at 17,500' don't show a whole lot of skin, and also don't show just how cold your toes can get up there!

As I rolled the SubSonex to a stop in front of my hangar this morning, the mighty TJ-100 spooling down and going in to its cooling cycle, I noted two milestones on my kneeboard. The first - I have accumulated 30 hours of flight time on the little jet. The second - I finished the final test card in the series from the EAA Flight Test Manual. Now "finished" is, of course, a relative term. There are a few tests that I will probably repeat to see if I can do them with more precision. And there are a few that got severely edited because, well - the manual wasn't written with a jet in mind! There are all sorts of strike-outs in my records, things like recording CHTs, EGTs, Oil Pressures and Temps - they are simply not applicable in the case of this machine.
