OK, new version. Changed the battery voltage selector so you can select cell count and the voltage-per-cell seperately. This should allow you to calculate "best case" speed with a fully charged battery, "worst case" with a almost discharged battery, and various spots in between. This was mainly done for Squee (I hope you're happy ;)).
Also added a motor selector that lists the BK Wanderer, LMT, and Lehner Basic motors and puts the kv value in for you. I didn't realize how big Mike's list was, and I didn't even put all his motors on there!!!

Oh, can a mod change the title of the thread so it can be found easier next time? Something like "Speed Calculator" or something?
