I hate Electrics, but I have two FOamys I use for thumb practice. My problem is, I can make any sense out of the discription of e motors. The Number Designations are complete jibberish. The only thing I can understand is the prop size, but it's rarely given.. What can you use to try to equate these silly things with real engines.

The simplest way is to find the motors maximum output in watts on its spec sheet. Some motors are rated in amps. If they are, multiply the amps by the voltage it will be run at and that will equal watts. One horsepower=746 watts (about the output of a .40 glow engine).
