Umm, did everyone miss the walking/jogging pace part?

That would indicate a top speed of about 10mph ideally, so something in the 1000kv range on 4-6s lipo would be ideal. Im thinking an XL feigao as they are much more efficent at slower speeds/higher voltages, and cheap. A big fat pair of 8000mah 2s lipos would be ample, and runtimes would be pretty much doubled compared to a setup aimed at high speed running- figure about an hour or more maybe.
