I've been pretty set that if I were going to be successful building something, it would be a Vans RV. Of course aerobatics are fun, but what I really enjoy about GA is going places, getting there quick, and getting there comfortably. I have a wife and two kids so naturally I'm drawn to a four place airplane. But I do recognize the argument that many make - how many times are you really putting four people in the airplane? For me that is probably only 25% of the time, if that. They say buy (or build) a two place plane and then rent a 4 place when you need it. That would mean building an RV-14 and then continuing to just rent a Bonanza for family trips. That would save considerably on the RV build versus an RV-10, but that would guarantee that this would always be my plane and not the family's plane. I want my boys to help with the build, and I want it to be theirs too. I'd say that is a very big part of this endeavor, and the RV-14 is just not going to work. Even if the upfront cost is higher and the operating costs is marginally higher for the bigger engine, there is no doubt in my mind. It's RV-10.
