I have seen posts on bashing the LT 40 but can't seem to find them , want to change to bolt on wing and convert to tail-dragger remove some of the dihedral and clip the wing anybody done any of these mods

Here's a thread on the LT40 that may help. Just do a search on LT 40

To stiffen up the tailfeathers, use some triangle stock between the horizontal stabalizer and vertical stabalizer. When adding the triangle supports use a sharp razor blade to cut away the Oracover on your kadet, and make a wood to wood bond with either CA or epoxy... I used Epoxy for that extra stiff bond. You can either paint the tri-stock to match your plane's scheme or pick up a Monokote trim sheet and apply that to it.

Happy Landings!
