KR> FAR Prop clearance
The key here is the attitude of the aircraft. With the plane level, yes, 9" is 9" regardless of the size or shape of the airframe. But I think the previous writer was talking about how that clearance is affected by the attitude of the aircraft. He also seems to be thinking the clearance is measured with the tailwheel on the ground - which I don't think is the correct way to measure prop clearance, even though most of the time the plane is on the ground the tailwheel is also on the ground. When I was learning to fly in a taildragger it used to always worry me that the prop might hit the ground if I pushed the stick forward too much during the takeoff roll. One day during the pre-flight inspection the instructor picked up the tail and showed me how high it would have to be before the prop would hit the ground. I never worried about it after that.

KR 19-8322 here in Aus. finally flew her first flight today, (and I am still buzzing) only for one circuit tho as there was a high EGT alarm but bar graphs were in the green, so it was landed on caution , Test pilot said it flew well just slightly nose heavy, just a few minor things to fix up now then on with the rest of the test fight hours.here a video of the first flight.http://www.youtube.com/watch?v=ZA1rSoiwS2I

There are a lot of atta boys and way to go messages on the list lately. It sure makes searching the archives time consuming. There are really rules for the list.

Dennis; First flight of my homebuilt was the hardest thing I have tried, including my Commercial and IFR check rides, and first solo! I love hearing from Oz and Argentina, (and NC)! Peter Thanks for reading my rant!Dennis DyerN5CJ
KR> atta boys
The atta boys are great, but they should be sent directly to the recipient, rather than to several hundred other people who've already read ten of them. I assume we can all figure out how to do that (hit "Reply", copy and paste the guy's email address from the message and into the "TO" field, then delete krnet at list.krnet.org from the "TO" field)...but I could be wrong about that. If the guy's name is there but not his email address is highlighted, you can usually right click, get PROPERTIES, and that'll show the email address to copy.
