Jim, My thought is you will want all the strength in the longeron that is available. So don't sand anymore than absolutely necessary, especially at the fire wall area. Some builders, I have observed on their websites, have added extra plywood on the inside top and bottom of the fuselage sides to beef up the firewall attachment. These builders are using the bigger engines for increased performance. I am using a 2180 VW and have 3-inch wide 1/4-inch plywood at the top and 2-inch wide 1/4-inch plywood at the bottom. The floor from the firewall to the main spar is 1/4-inch plywood inside for added strength (and for big feet per the KR-2 plans suggestion). All these added plywood pieces are gusseted into the firewall frame. Perhaps this is overdone, but I want to avoid a citation from the EPA for littering the landscape with old KR-2 bits and pieces. Environmental cleanups are getting so expensive these days... Sid Wood, KR-2 N6242 Mechanicsville, MD USA sidney.w...@titan.com

The 5/8 x 5/8 piece that sits on top of the top longerons about 4" back. Since the sides angle, it does not sit flat on the longeron. Should I notch that cross member or sand the longerons level like you do for the bottoms? Thanks for any advice.
