If you have a typical empty weight of 1100 pounds that gives you 500 pounds for people and fuel. If you and your passenger weigh 425 then you can only put on roughly 10 gallons of fuel. Also, you must stay within the aerobatic aft CG limit of 26.5% of chord or 15.3 inches aft of datum (leading edge of wing). Having said this, remember that the aerobatic gross weight is the maximum weight that the structure of the airplane can support the 6G limit of the Aerobatic Category. A typical loop requires about 3 1/2 G's, far from the maximum structural limit. Personally, I have no problem with doing a loop with the gross weight slightly above the 1600 pound aerobatic limit, but I would be cautious about exceeding the aerobatic aft CG limit, especially if you are doing high angle of attack maneuvers such as stalls and spins or maneuvers that could put you into a high AOA situation if you screw it up, like a hammerhead turn or immelman. There are a few small computer programs that will compute your weight and CG for different loading situations. They are fun to play with will clearly demonstrate the limits of your RV-8. Dan Checkoway has some data on various RV's that show the aircraft weights for different engine/prop combinations. Check it out at http://rvproject.com/wab/. You can click on any of the aircraft listed and then input your sample load data to see what happens to your gross weight and CG. Dan's site has a wealth of information and you can spend hours flipping through it! My suggestion: build your aircraft as light as you can. All of the fancy instruments and bells and whistles are nice, but they all detract from your performance and useful load. Take a look at an all-out aerobatic aircraft like an Extra. Most have a basic VFR panel with a handheld GPS, no interior paneling, carpeting or soundproofing. But if you are building an RV-8, you are not interested in unlimited aerobatics so your aircraft will have many compromises that suit your particular needs. (After all, this is why you are building a custom airplane, right?) I enjoy an airplane that feels like a fighter; is fast enough that cross-country travel is a pleasure, not an adventure; is comfortable in formation and turns me upside down when I feel like it. The RV-8 fills all of my needs. Hope yours does the same.

Mine is 1600 / fuse #1005 and rivets were placed in these holes at the factory. So sometime before #1005 the change was made.

I am in no hurry, so next time at Stanton's would be fine and save you the trouble of mailing them. Turns out my 3 young grandsons are "patch happy" - what better patch to give them. I have also attached several to T shirts using a "patch" glue for fabric - will see how well they hold up.
