Folding wing aircraft are generally nothing like as adaptable as their designers would have you think. It is possible to tow a Kitfox/Avid - but the wings need bracing and they are very vulnerable. They will probably need most of the fuel removed as well.
It can be done but the vast majority of folding wing aircraft don't - and that by itself is a telling comment. Certainly the aircraft are out there for sale. Go along to your local Strut and try and find a local owner who has a similar type of aircraft - the things they know will save you a huge amount of aggrevation. Or go along to your local strip and do the same. There are so many differences between the club and strip environment that setting up by yourself will be a real challenge - use other peoples experience. The majority of strip flyers are all too eager to help particularly if you can offer some talents in return.
