I'm not so sure about that. I had my tail feathers inspected early by the MDRA. They didn't seem concerned at all that I had only primed mating surfaces. Lots of bare alclad inside the empennage with the MDRA sticker right there.

In the rv8 the pilot sits aft of the CofG...maybe a heavy prop would be a good way to balance this aircraft out?

Battery - Up front in my case!
The -8 flying solo is more CG forward than you'd expect. And you're a big guy. A norm with most pilots is to load the rear baggage compartment with +/- 40lbs weight to offset the CG. I know of a few who created a lead shot container in the tail cone with easy access to pour weight into and take out depending on either passenger requirements or aerobatic performance. Locate the battery in the back is a start - but do consider how you want to land and CG category you prefer flying as solo pilot.

You had a nice inspector. I've had to make changes to mine before.
