Dewalt is a brand - like Ford - there are quite a few different motors under the DeWalt name. Here is a link to some of them

In general though, nearly all of them make more power than the scooters do - most drills make between 0.5hp (370 watts) up to 2hp (1500w) depending on what voltage you run them at.

I'm not certain as to whether the scooters watts are input or output watts (taking in account motor efficiency), but if its input watts, then the output has to be less than 300, if its output, then its still less than most drills.
The big advantages of scooter motors are reliability and power consumption. If you are not building a ram/pusher then you dont need kilowatts of output power, and scooters are much easier on your batteries and ESC if you can handle the weight penalty.
In fact, scooters power/weight is even worse than they first seem, since the power ratings are at 24v for scooters, meaning you need to carry more battery cells to get the rated power.
However, like they say, its not how much power you make on the first lap, but how much you make on the last lap that counts. Drills are fragile, amp hungry beasts that break often, but are cheap, easy to use and light. _________________ Great minds discuss ideas. Average minds discuss events. Small minds discuss people
