Thanks for the help Jim, Sal was able to order me an Aluminium rear pod with a built in motor fan from 3Racing. What I do need to know is what rubber tire compound would work on the F103 AND the F201 for medium high bite carpet? We also have an asphalt track under the carpet and I would like to know the compounds for asphalt too. I'm not sure what the grip is on the ashpalt seeing as we haven't run on it yet, it's brand new!
