C'mon guys - this isn't rocket science and nobody here is stupid. I see msg
after msg with the same quote - if you have such an ego that you feel we
can't figure out what you are referring to at least trim all the headers and
unnecessary flak from the quote. We all get the same messages and can look
back if we need to reference a previous post. All this quoting does is jam
up servers with no real value.

| Subject: | Feedback Request (Alternative Engines) Kitplanes Magazine |
--> RV-List message posted by: Cory Emberson <bootless@earthlink.net>
Hello all,
I would like to hear from you if you're a builder who has successfully
installed and flown an alternative engine in your plane. I'm compiling a
builder's roundup for Kitplanes magazine, and am looking for an
installation that's flown for a minimum of 300 hours, and is currently
flying.
For the builders that we profile, the magazine will also be able to pay
you $100 for the write-up. I'll be at Sun 'n Fun until late morning on
Friday (April 7), so if you fly in, I'd be happy to take the photos
there. If not, we would also need at least 2-3 good photos, including a
close-up of the engine and an overall shot of the aircraft. Additional
photos would be great, and all photos will be returned. If you have
digital photos, it is very important that they be high-resolution, at
least 300 dpi. I have a list of specific areas to address if you'd like
to participate, but we can handle that off-line. Please feel free to
contact me off-line at: bootless (at) earthlink (dot) net (my despammed
email address).
Thank you so much!
best,
Cory Emberson
Contributing Editor

For those of you interested in LIVING with YOUR AIRPLANE. There are two properties for sale at Big T airport (64GA) just 6 miles from Tarra Field's aerobatic box. Both properties have residnetial accomodations attached to hangars with over 3000 sq ft of hangar space and over 2400 sq ft of living area in the homes. One property has a joint 1000 gal fuel tank. Both properties are located ON THE RUNWAY. One property is asking $399,900 and the other is asking $385,000.
