Maybe "bad habits" is a little overkill. It's just a little trickier than something like a 4* or Tiger-2. You'll need to use little more rudder than you might with other planes and being so large but so light it can get tossed around pretty good in the wind, especially on landing. It's not going to tip stall like a P-51 or anything, just not as friendly as some other planes for someone graduating from a trainer.

I had mine at our clubs giant scale fly in today and I somehow broke the wing tip. Everyone seems to think they saw it happen differently but I drifted to the edge of the runway on landing and I think it caught a pretty tough weed or something.
