I guess the Bobcat is a related topic since it is the little brother of the Tiger Tail. The two I had both used a K&B 40 with a Perry carb but no pump or muffler. Both planes were covered in Solarfilm and flew great. One was the victim of a bad radio and the other pushing the stick the wrong way when inverted. I just picked up a Bobcat off of Ebay and plan to clone a fuselage since I still have the wing from the second one. Then maybe later built the kit.
