I’m looking for feedback on adding wire routing holes to F-806B and F-807A. Specifically, I could use an additional set on the right side so that I can route the transponder antenna cable under the floor. I have the one set, matching the left side battery cable routing holes, which I intend to use for ADAHRS and A/P pitch servo cable wire routing. I’m planning 1 ea. 5/8” dia. hole in F-806B at 2.5” outboard of the rudder cable hole and just outboard of the F-813R-1 Seat Rib in F-807. Van’s has no comment. Guess the builder mod’s here have been too many and varied to analyze each one. I’m more than willing to go on past experience.
Also question re battery installation. I’m going with an O-360 and 3-bladed Catto prop, so I think a forward battery makes sense. Was looking at the lower right side of the baggage compartment, but that looks next to impossible in a QB. Has anyone else done that?
Thanks in advance for any and all comments.

Hi Stan,
The RV-8 is really setup nice for a rear battery installation. Works out very nicely. My RV-8, while it does have a Hartzell CS prop, its REALLY nose heavy, especially flying solo. If you're going with an IO360, I think you're still going to be fine with a rear mounted battery even if you go with a lighter Catto prop. I wish I could put TWO batteries back there...

Stan,
I've documented all of your questions on my web site. I ran cables in every possible niche.
I have the IO-390, MT CS 3 blade, one battery in the lower front baggage and one under the aft baggage shelf. My plane is not nose heavy at all - solo or dual.
Mine was a QB and installation of the forward battery was not difficult, just time consuming.
Contact me offline if you'd like links to the photos showing the areas you have questions about.
Regards,
Stan Sutterfield

Hi Stan,
I would have used the right lower baggage compartment had I thought about it early enough. I couldn't figure out how to mount the battery securely after having riveted up the floors.
On the cables in back, I drilled a couple of holes, made doublers for the bulkheads and think it is pretty secure. I do have a tendency to over build things, so my bird will not be the lightest. Let me know what you decide.

I have two Odyssey PC-625 batteries, one mounted on one each side about 6’ behind the firewall. The fuel pump is moved off the floor and mounted vertically to the bulkhead on the left side so the battery can be mounted to the floor. Running with a 180HP IO-360 and Hartzell CS prop. This has work out well for me and at least two other RV-8 builders.
