Ice, She'll do a pretty good flat spin. It lacks elevator to get it really flat but still, not bad. Nice and slow decent when you really get into it. I don't notice any bad habits, just make sure you add power when you want to pull out. Keeps everything under control. I've got my USL ready to go after a major rebuild. I'm now using a YS 110. I did quite a bit of lightening and have the weight down to just a tad over 9lbs. I think she's gonna fly great but I haven't tried it yet. Maybe this next weeks sometime. My above info about spins is based on last year when I was flying her with a OS160FX.
Thanks, and good luck,
Barry
