Today was weight and balance day for the IV. We
didn’t come out quite a light as I had hoped, but not too bad. We’ve also done
everything we could to move the empty CG forward. All 3 batteries are on the
forward face of the firewall. We have a 13.5 gallon header tank between the
right side of the instrument panel and the firewall and we moved the engine
forward 1 inch. These are the numbers for the normal 4 place
configuration:
Empty weight: 1,944.5 lbs CG: 87.15”
Fuel capacity: 130.5 gallons
We’ve also built the airplane to be easily
convertible to a two place configuration with 186 gallons and a single place
“expedition” configuration with 399 gallons. I know that most of us have used
higher gross weights than the factory number. I’d be interested to learn what
you guys have used. Thanks.
