Specs for 30''-32'' KFm2 FPV wing?
Just looking for some specs on a FPV wing 30-32 inch? It needs to be able to carry light FPV gear and a 2200mah battery.

Why are you needing it to be 30-32 inches? With that big a battery and radio gear I think it would be really hard to launch. Look around most fpv rigs are bigger than that. Maybe you could launch it with a catapult rig or bungee launch it though.

Don't limit yourself by the width of your foamboard. You're building a layered wing, so join sheets and stagger the seams for a wider span.
This is a 40" kfm4 3-sheet $tree foam paper-off wing with 15" root, 12" tip and 12" sweep. It weighs 615g AUW with a 2200 3s and floats around for 30 minutes with a 2208-1260kv spinning a 8045sf prop.
This was my favorite wing till I started hotwiring and it still sees regular use. The top and bottom layers are seamed in the center and the middle layer has seams 5" from each tip and doesn't require tiled plans, just measurements around the perimeter of your foamboard and some straight lines connecting them.
