I was able to get the fuel tank included with the kit (don't know for sure how much it holds) and a DuBro 24 ounce under the wing tube. I will use the DuBro tank for smoke fluid. The Sullivan flexible tanks are made from a different plastic that allows them to be heated and mold them to some extent. I would assume the properties of the tank may cause it to swell with gas as does some silicone tubing. I received ny AI pilot last night and muffler for a 3W engine. May be ready to fly this weekend, but it does not look good weather wise here in central Indiana.
