Ah, an "on topic"post.

Before you convert, take some measurements on your aileron horns and linkages, to see how much room you have inside the fuselage for them after you add bolt-on thread blocks.

Every single conversion I've seen where the thread blocks are inside the fuselage, the blocks interfered with the aileron horns and linkages. That may bewhy the OP hasn't posted again.

DuBro makes a nice conversion set, to be located outside of the fuselage. Then you just have to beef up the wing, where you put the attaching bolts through.

Good luck,
