I've just used magic tracks on a Dragon Panther. Easiest way I found was to build them before I put the hull together. Build the road wheels and suspension as normal from the plans. Then put the tracks together but dont glue anything. I put down a lenght of Tamiya tape sticky side up and just pushed them together on the tape. When I has the righ lenght (you can check easily check it by by just offering up the tape attached run) I ran some liquid glue on most of the joins, leave some gaps so you can take the tracks off again, and attach the tracks to the road wheels. Leave them to dry and just pop them off after. You can paint the part runs easily and put them back on when the build is nearly complete.
This way worked for me, hope I've explained it so you can understand, if not drop me a line.
