Also, when converting to tail dragger, make sure your gear mount in the fuselage both in front of the wing and at the tail is satisfactory for the load it will be getting. For the tail wheel setup, remove the covering, clean the area, cut a piece of ply, 1/8 minimum, in the shape of the area where you are going to mount the tail wheel assembly, and CA or epoxy it in place.

In front of the wing, make a length of hardwood or thick ply, and epoxy it in place. Make sure you install braces to formers to secure it and keep it strong. Then you can either install blind nuts or drill/tap the hardwood, apply CA to the threads, and mount your landing gear using nylon bolts. The nylon bolts will give you a breaking point that will save the fuselage in case of a very hard landing. The bolts will shear off instead of tearing out the bottom of the fuselage.
