The face of the cowl that aligns to the rear of the spinner is = not square with the plane. It is designed to align properly when the = engine is properly offset. That should give you a clue that you have the = offset correct. If you use rubber motor mounts that are too soft, they = will allow the engine to sag and screw up your alignment as well. Be sure = your mounts are ok before you align and fit your cowl. (Guess how I know = this.)

I am really blown away by that prop! :>) I can = hardly wait till you crank it up. My plane causes the front strut = to bottom out when I firewall it, but if you saw the video of Tracy’s = plane and think what yours will do with the turbo….It causes some scary thoughts!

Be sure you tie it down and don’t just chock the = wheels….It may retract them…to the rear!

I was wondering if anyone would notice that = Bill. Lancair called for 1.5 degrees to the right, and down, for their stock Continental/Lycoming layouts, and with much discussion, we decided that = it would work for us. We have 4" clearance with the tire flat = and the strut compressed, that should be enough I hope. That fan is nasty = looking isn't it.....(:-)

Looks really good, Greg. What thrust line offsets did you = use when you built your engine mount? How much ground clearance do you = have with that monster prop?

By the way, everybody. I have a set of prop bolts that = came from Saber Mfg. that I didn’t use. They are 7/16 X = 6”. If anyone could use them, I can make you a good price. I screwed them = in one time, but realized that I needed to add an extension, so couldn’t = use them.

A couple of you wanted to see what's going on, so = here we are. Manifolds are out getting flow tested and final welded. = Next week is plumbing and wiring time. Gotta' take a couple of days = off, and do Hunney-do stuff. God, I love this = stuff......(:-)
