RE: 2nd plane
Bruce is correct, there aren't too many RTF's once you get past trainers. This is because the RTF market is aimed completely at those who want to get in the air, but don't know anything about planes, and don't want to spend time putting a plane together. Usually when a pilot solos he's started to get ideas about what he wants in a plane and what type of hardware, engines, radios, etc... that are in his plane. Because of this an RTF is no longer a good value, so that's why you don't see many out there.
