I've never waxed them but always wipe mine down with baby wipes with Aloe and it keeps them slick .
Don't really know if it helps as I always do it but sure helps keep the bugs sliding off most of the times
dirk I thought you would be all over that. getting 3 more miles to a tank full. I remember my brother gave my some wax years ago for planes. very $. it was made to reduce drag on the fuselage. I know that does not really matter with the quad. but it may help with the props. I'll have to get my turtle wax out and see what happens.
