Well then, in one of my clubs we had a racing class that was designed for one type of ARF only and most the guys would remove the ARF covering and recover it the way they wanted. Covering isn't very hard, Ken has a how to thread here that is very good.
Stop dreaming and give it a try, several of the guys here will be more then happy to help you out with any problems you may run into. Even if you want to try building a plane instead of assembling them. We don't build them because it's easier, we do it because they are stronger and it just plane fun!!
