For those looking to calculated the approximate top speed of your board I’ve adapted an excel sheet that Vitalie created.
Download here: cogs

Note: Going at 15mph or 24kph feels fast.
Basically when looking at motors you want something with a low KV (rpm= KV8 voltage). Also in the spreadsheet is gear ratio and wheel size.
Now this isn’t going to help you figure out what wattage motor you might need. Mine is a bit over 2000W and heaps of power. As you would see from my previous post I’m looking ways to make my controller less twitchy which will most likely mean some ESC changes.
Found the link to the ESC. This could be” fun” http://www.hobbyking.com/hobbyking/store/uploads/573447592X53414X54.pdf
