Unfortunatley. ?In exchange for a little RV flight time? can be considered a thing of value, and therefore compensation.....which is, of course, illegal in an experimental without a LODA. I?ve been doing some research for an article, and perusing FAA interpretations, and ?compensation? is a large portion of those interpretations. And wow - you can?t imagine how easy it is to get crossways on this topic!
Better to just ask if someone might want to give you a chance to fly in an RV!
