$10 for a 250W scooter motor sounds like an OK deal.  What are they
charging for shipping?  That's where some of the eBay vendors make up
their money.

This motor will give you 1/4 of the power of an EV Warrior at 24V.

I propose a new official baseline power measurement for motor
comparisons in the hobby.  It would be called the Cromwell and would be
equivalent to 1000 watts of power.  In the metric system the Cromwell
would be expressed as the "Tyng" (less letters for the Imperial
challenged).  In the case of the 24V/250W scooter motor it's power
output would be expressed as 1/4 Cromwell's (or 250 Milli-Tyng's, 2.5
Deci-Tyng's, or .25 Tyng's).  An EV Warrior motor running on 12 volts
(approx 300W) would output about 1/3 Cromwell's (or 300 Milli-Tyng's, 3
Deci-Tyng's, or .3 Tyng's).  This system would give the prospective tank
builder an idea of the power and speed capability of their proposed tank
project against a known performance variable in the hobby.  IMHO this
proposed baseline measurement system will do nothing but promote the
hobby by cutting through the many arcane, obsolescent and incompatible
power measurement systems currently in use today.
