The packing tape will keep the LE's intact just incase you hit a tree branch or something. It also adds to strengthening the wing. I've put my moth in a couple trees now, and if it wasn't for the tape, I think the branches would have ripped into the wing. I made the mistake of not covering the very tips, they are all chewed up, but the rest of the LE under the tape is fine. The batt would be the 370mah, sorry.

I know what you mean about retraining yourself, I went from .40 glow to this little bugger...from four lb's to 9 oz's.... ! I did start with a heavy battery and my plane ended up heavy, but it still flew OK. After I dropped in the NiMH, I lost about an ounce. Sure doesn't sound like much, but it made a world of difference to the plane... !

One thing that you will notice with this plane...that is that the wind is ALWAYS blowing ! My girlfriend keeps picking on me because I'm forever looking at trees to see how much wind there is... .
