RE: Ace Extra 230 33% Fiberglass
Actually thanks for all the info, as it turns out most all my parts are cut to the wrong sizes.
Firewall 4 x 4 3/16
F1 opening 4 x 4 1/8
engine box sides 4 3/8 x 9 15/16
engine box top & bottom 3 3/4 wide which would be the correct width if they were put inbetween the sides and if the sides weren't 1/4" to tall.
Yes my plans show the balsa sheeting over the F1 former and they show the front 2 3/8" of the hatch foam is attached to the F1
My plans are showing the centerline of F1 is 3 5/16" down and the rest are 1 5/16" down from the top.
I think your right about just cutting all new formers
