| Subject: | Re: Position of the battery in the RV8 |
There's a good listing of various RV W&B figures at:
http://www.rvproject.com/wab/
As for where to put the battery, I've done it both ways now, and my current RV-8
(O-360, Hartzell) has an Odyssey battery on the firewall. Tandems are always
a compromise when it comes to CG, but at least the RV-8 offers a large front
and rear baggage compartment to even things out.
Bottom line is that the only time you will really NEED to keep the CG from being
at the forward limit is if you have an inverted oil and fuel system, and plan
to fly inverted. I've been told that there isn't enough down elevator for inverted
flight at the foward CG limit, but I don't know this for a fact. I do
know that my previous RV-8 had an aft mounted battery, and took a lot of down
elevator to fly level inverted.
Mounting an Odyssey battery aft might be about the best situation, but getting
to the battery is a hassle, and you add weight by having to run a battery cable
forward. You could take that same couple lbs, and add it to the tail to make
up the difference, and have the battery on the firewall where it's easier to
get to. That was my plan this time around, and so far, I'm happy with it.
Cheers,
Rusty

Jose,
A French girl (who does speak Spanish) responds to a Spanish guy in
English
via a US list ' are we international or are we international?
This issue was debated fairly recently in one of the lists as I asked
the
question. The consensus seems to have been that generally RV8s with CS
are
nose heavy when flying solo and difficult to three point. Based on all
the
discussion that my question generated, I went for the aft position '
I=92ll
have a TMX-IO360, forward induction hence a snorkel up front with an MT
prop
and Skytech light weight starter. Time will tell whether this was the
right
choice.
I do have a friend with an angle valve (200hp) and CS Hartzell ' he
had to
put 10lbs in the tail to balance his plane out.

I'm ready to order the Van's wire harness kit for a RV-8. I need to know
if
the battery will be aft or forward mounted.
What is the experience of other builders with a O-360-A1A

I had a buddy once who when flew with me couldn't trim his airplane enough
when he slowed to my speed. He added a small door at the tail where he
could add a temporary weight. Maybe that is also a good idea in this case.
Add the weight when you need it.

| Subject: | Position of the battery in the RV8 |
I just moved my battery from front to back in my 8 after speaking with a
friend who has the same engine and prop I plan to fly, TMX IO360 and a
Hartzell blended airfoil. He has been flying around with a case of oil in
the back so the landings are a bit easier. Since I usually will be solo, I
think that is the best way to go. I shouldn't have to get to the battery
that often, so access is not a priority. I may add a ground power socket
aft of the baggage compartment.

Kevin,
If you have aerobatic mounts, you might make it. If you have the standard
shock mounts, you will probably need a little more clearance. consider
adding 1/8 inch more.

| Subject: | Instrument mounting hole circle |
I'm about all archived & googled out and the best I've come up with for
mounting screw hole diameter for standard 2-1/4" instruments is 2-5/8" (2.625).
Can someone please confirm this before I commit expensive aluminum to the cutter?

And another thing-
For any of y'all that have powder-coated your panels, what is the prudent
allowance around openings such as instrument holes to allow for thickness of the
powder coat? I imagine this may vary a bit from one coater or coating to the
next, but what is the best bet? Any recommended coaters out there?
Also appreciate any additional thoughts or recommendations on panel power
coating from those who have BTDT- off list replies would be fine!
Thanks once again-

Mine's powder coated and in reality it doesn't really make a difference.
Make the holes the right size for the instrument. If it's a tight fit
because of the coating then just file off the coating. You won't see it
on most installations because of the instrument bezel covering the hole
gaps.
One thing to be aware of, if you powder coat your panel and you intend
to use a non-smooth coating for anti-glare purposes like I did,
it may be more difficult to apply and not 'see' the decals to mark
instruments. Lots of options with powder coating though and it's a
very durable coating which I'm very happy with.

I would recommend making the hole diameters about 1mm (.040") oversize but
Walter was correct that you can scrape the inside of the holes with a sharp
Xacto blade to get rid of the meniscus.
