Hi all, I'm buliding the 4*40 now as well and tonight I did the sheeting on the turtle deck. Using 1/16 sheeting butt joined (?) the sheeting at the center stringerr and ran it down to the fuse. Filled in the lap joint(?) with Micro Fill and will sand smooth tomorrow. Pretty easy mod to do after taking a few measurements and cutting two pieces the same. Will takle thew canopy later and hope I can figure that out without screqwing up the one that came with the kit. Also reinforced the landing gear ply block with 1/4" triangle and drilled it for 1/4-20 plastic bolts. Oh yeah, also reinforcede the the fuse former right behind the wing with more 1/4" tri stock. All of these done as per great advice passed along on this forum.
