A motor hasn't power ==> A motor can handle a given power.
And the Castle can handle more power than the tekin, that's mean geared for the same performance in the same chassis, the castle will run cooler and longer than the tekin, consequently you can gear the castle up and have better performance than the tekin with same runtime and same motor temp.
the castle is heavier, that's why it can handle more current or power : the wires inside are bigger than tekin wires for example...
