John,
That's comforting but I think I've been persuaded to do the door in the
floor thing. I'm really wary of aft CG's since I've been living with one
for 220 hours with my Kitfox. It's a IV-1200 with the Grove spring gear.
As for landings I wouldn't mind if the tailwheel 9 is a bit easier. In the
Kitfox I've found that, for me at least, reasonable landings are fairly easy
to come by and good ones are not.
Bill

Bill,
That's very persuasive so I guess I'll head in that direction. I had a look
at your pictures - nice job. A few questions: Was there any particular
reason you hinged the doors? Did you feel it necessary to consider the G
loads the ELT would suffer in a crash and beef up its mounting accordingly?
It doesn't look like the Ameri-King ELT? Is it 406 MHz Artex? If not, did
you make any provision for switching when the time comes? Could you
describe the way the sides of each bay are done - material and attachment?
And again, thanks for the help.
Bill C.

Bill,
Regarding the G loads, I did not give it any consideration. The ACK ELT
(http://www.aircraftspruce.com/catalog/avpages/ack_tech.php) that I am
using is bolted to the baggage compartment rib, not the bottom skin.
The idea was to keep it from vibrating on the bottom skin. I don't know
if this will work or not, time will tell. My tech advisor did want me
to move it to on top of the baggage compartment floor so it is
accessible in the case of an accident. I have elected to leave it under
the floor but will use thumb screws so I can access it in the event of
an accident.
>From what I've been reading, most of the accidents that trigger the ELT
are such that the passengers don't survive so I'm not really too worried
about it's placement. One thing nice about having it under the floor,
if I do get into an accident, it will most likely not become a
projectile.
A side note to this, after placing it there and running the phone line
and antenna wire through the other floor ribs it was pointed out to me
that certified aircraft try not to run these wires through ribs because
in the event of an accident the rib can cut the wires. Just another
thing to consider when you select your placement. I'm not sure if the
phone wire that goes to the control switch is that critical but I
suspect it could be cut in such a way so as to deactivate the ELT,
again, I'm not really sure about this.
If I had to do this over again, I doubt I would include the hinges, just
use the screws to hold the tops in place. I had extra hinge laying
around and used it, which is just like me to make it more difficult to
build.
As I said above, the ELT tray is bolted to the side of the floor rib
with 8-32 plate nuts. The lids were made from an extra tank skin I had
laying around (don't ask).
The strobe light power supply was similar in construction, only I bolted
it to the lid itself. Again, in an effort to keep from mounting
anything directly to an outside skin. Someone once told me not to mount
anything to an outside skin because the flexing of the skins could cause
stress cracks. This may be an old wives tail, I don't really know.
Bill

When Van put the battery on the firewall it added extra margin w/regards weight
aft of CG. I have built a RV-6A, RV-8, & RV-7A and all have the ELT in the tail
below the horizontal stab., and the strobe power supply just aft of the rear
baggage area bulkhead. The CG's on all turned out as Van predicted. The six
has a O-360 180.hp and metal prop, the eight has a IO-360 w/CS prop, and the
seven has a IO-360 w/CS prop. The eight and seven even have the Alt hold auto
pilot servo in the area behind aft bag BH too. I put the ELT in the tail because
that is the portion of the plane most likely to survive in a incident etc.
Note that 100# of baggage is A-LOT! Pick your largest suitcase and fill it to
max then weigh it.....you'll be surprised. You can not get that size s/c in the
bag area anyway. A couple carry/on sizes is about it.
Good luck.....& build on!

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

and now here I am about 95% finished with a 9A. Tell me your Kitfox

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 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.</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>Don't be disheartened. The Gear on the RV9 is much more reliable than
the bungy gear of the 'Fox.</DIV>

Hey Larry,
Do you have any pictures you can share with your ELT mount in the tail of
your 7? And antenna placement? I have the AK-450 ELT to go in my 9A with
slider, and am still mulling over its placement.
Thanks!
Mike

When Van put the battery on the firewall it added extra margin w/regards
weight aft of CG. I have built a RV-6A, RV-8, & RV-7A and all have the ELT
in the tail below the horizontal stab., and the strobe power supply just aft
of the rear baggage area bulkhead. The CG's on all turned out as Van
predicted. The six has a O-360 180.hp and metal prop, the eight has a IO-360
w/CS prop, and the seven has a IO-360 w/CS prop. The eight and seven even
have the Alt hold auto pilot servo in the area behind aft bag BH too. I put
the ELT in the tail because that is the portion of the plane most likely to
survive in a incident etc. Note that 100# of baggage is A-LOT! Pick your
largest suitcase and fill it to max then weigh it.....you'll be surprised.
You can not get that size s/c in the bag area anyway. A couple carry/on
sizes is about it.
Good luck.....& build on!

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 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.</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>Don't be disheartened. The Gear on the RV9 is much more reliable
than
the bungy gear of the 'Fox.</DIV>
