You won't know until you know......
My w/b with x320 and metal prop, and the elt and power supply behind the baggage
bulkhead; would allow for over 100# of baggage so intuitively it suggests that
a lighter prop would be accommodate that location for the elt and power supply.
I went through all of the various loadings on the computer, and could not get close
to the edge of the envelope.
The 9 is a fine flying machine, lands just like a kitfox.

Hello Listers,
I just wanted to send out a reminder to all of the Listers regarding the new-ish
BBS (Bulletin Board System) Forums that are available at Matronics for the Email
Lists. The BBS Forums give you Web-based access into the same email content
that is generated by the Email Lists. When an email message is posted to
any of the email lists, a copy of the message is also copied to the respective
List forum section on in the BBS Forums. By the same token, when a message is
posted within the BBS Forum interface context, it will also be posted to the
respective email list.
Basically, the BBS Forums give you yet another method of accessing the Matronics
Email List content. Some people prefer email, some prefer web forums; now you
can have it either way or both with the Matronics Lists!
You'll have to register for a login/password on the BBS Forum to _post_ from the
BBS, but you can view message content without registering for an account. To
Register for an account, look for the link at the top of the main BBS Forum
page entitled "Register". Click on it and follow the instructions. Site Administrator
approval will be required (to keep spammers out), but I will try to
get these approved in less than 24 hours.
If you haven't yet taken a look at the Matronics Email List content over on the
BBS Forum, surf on over and take a peek. Its pretty cool. The URL is:
http://forums.matronics.com
I want to stress that the BBS Forums are simply an adjunct to the existing Matronics
Email Lists; another way of viewing and interacting with the Matronics List
content. If you like Email, great. If you like Web Forums, great. If you
like both, great. Its up to you how you view and create your content.
You will also find a URL link at the bottom of this email called Matronics List
Features Navigator. You can click on this link at any time to find URL links
to all of the other great features available on the Matronics site like the Archive
Search Engine, List Browse, List Download, FAQs, Wiki, and lots more.
There is a specific Navigator for each Email List and the link for this specific
List is shown below.
Thanks for all the great list participation and support; it is greatly appreciated!

Now you've dampened my enthusiasm. After 1200 hours in a V-tail Bonanza,
I
built a Kitfox IV Speedster about 10 years ago. Sweetest flying plane in
the
world, at least until I tried to put it on the ground on an asphalt runwa
y.
I'm sure a lot of it was me, but I found it to be the squirrelliest thing
in
the world with variable winds on the ground. Only plane I ever ground-loo
ped
and now here I am about 95% finished with a 9A. Tell me your Kitfox
comparison was for a 9.

My frame of reference is that in 700 hours and 2000+ landings on asphalt and high
altitude mountain strips I have yet to experience any difficulty landing the
Kitfox. The rest of my education is still to come.
I found the 9 easier to land than the RV7 that I was in for transition training.
I typically cross the fence at 60-65 mph IAS compared to 85 mph IAS in the
RV7.
Don't be disheartened. The Gear on the RV9 is much more reliable than the bungy
gear of the 'Fox.

<DIV>My w/b with x320 and metal prop, and the elt and power supply behind <BR>>
the baggage bulkhead; would allow for over 100# of baggage so intuitively
<BR>> it <BR>> suggests that a lighter prop would be accommodate that location
for the e <BR>> lt <BR>> and power supply.</DIV><BR>>

<DIV>I went through all of the various loadings on the computer, and coul <BR>>

<BR>> Bill, <BR>> <BR>> Great info and thank
you very much. <BR>> The fellow I asked <BR>> at <BR>> Van's was singularly
un-helpful with this. His <BR>> response was to n <BR>> ot <BR>>
worry about the CG and if it came out too far aft use a <BR>> metal <BR>>
propeller. Sort of missed my point about wanting to use a wooden one <BR><BR>>
> <BR>> and provided absolutely no ideas about where/how to locate
things like E <BR>> LT. <BR>> <BR>> strobe power supply, etc, farther
forward. Was pretty adamant ab <BR>> out <BR>> not <BR>> making
the baggage area floor removable, though. <BR>> I <BR>> conclude from what
you said that I should have no problem if I go ah
ead <B
R>> <BR>> and mount the ELT and all just behind the 706 bulkhead and, abse
<BR>> nt <BR>> anyone <BR>> commenting to <BR>> the c <BR>> ontrary,
I think that's what I'll do. <BR>> Bill C. <BR>> <BR>> <BR>>
