Wow

. I'm surprised by all the responses. Thank you all very much.
I was thinking about a BEC and fan, but don't know what a cap is. I'm sure it is a capacitor, but what kind, where do I buy it, and how do I install it.
I'm going to give the A123's a try for now. We'll see if they stick around.
A skid plate is definitely a good idea. I thought I'd put the battery down there to keep the CG low, but your right that it needs some protection.
Thanks,
Pete
