Tim,
You can prop the plane to be ballistic if you want to fly that way or you can buy a higher KV motor or some other combination thereof. When you do, either your vertical will suffer or you'll be drawing more current. If you go the more current route, just be sure all your gear is up to handling it. There are no limitations here except the FAI/AMA imposed 50V maximum.

The single hardest problem I had going to Electrics was NOT getting a sound report back from the engine like we do with IC engines. I would be flying along and the airplane would start sinking until I realized I'd never pushed the throttle up. Another thing is with electrics is waiting on the airplane to get to where you want it to be, it'll get there, you just learn to wait. They don't go ballistic like my YS powered planes would do.
I prefer electrics in every aspect now.
When George Asteris changes to Electrics that is the end of IC in the pattern world. I think even CPLR will change before George does. We're working on him at every contest.
