What gjeffers said. He's right but I'll offer my two cents worth too.

1. Yes, the 46 will flat spin excellently, both ways. Few planes do it better.
2. OS 70 is not enough engine for this plane if you want to enjoy it.
3. Yes, it's easy to hover. I use an 82 and it's plenty, but a 100 is even better.
4. Rolling circles are easy and not too pretty. It's kinda sloppy, but that's probably me more than the plane. I can do them but they look better when I do them with my Showtime.
5. Mine has a lot of wing rock when doing harriers. Better inverted. Not it's best move.
6. It's an easy build. I like to build them. I've had plenty of paractice. Landing gear is weak and is best if reinforced slightly. The wings "rattle/drum" quite a bit but I've grown to love the sound. Book says 6 hours.....Takes me 20-30 to do it right.
7. The UCDs are my favorite planes. Can't go wrong with them. But use plenty of power.
Thanks
