I wouldn't see anything wrong with diving into a Spa3d as a second plane at all...however...ONLY with the help of someone experienced with one. It's not hard to fly, but it's a completely different animal than a trainer. In the hands of someone not experienced in the set up and trimming out of one...at the least it could be a wild ride...at the worst could be dangerous. I don't want to ever see someone get hurt with one.
