New to electrics and need some help.The many confusing numbers asigned to the electric motors is frustrating.Is there are chart where one can compare manufactures?Common numbers from E Flight like 370's anf 450's 480 etc.
Then Hacker has some other numbers..and so on.
The Ulrafly motor Ultrafly B/12/10 would be comparable to which motor in the E flight line up? (Both outrunners)

One attempt at a motor comparison is [link=http://www.flyingmodels.org/index_en.htm]The Great Electric Motor Test[/link]. It is by no means complete, but it's quite an effort.

The numbers are just marketing names. They're meaningless as far as making comparisons or determining if a motor is suitable for a particular application. Ford calls their truck an F150, but Chevy calls theirs a Silverado 1500. Same thing with the motors... 400, 480, 22/33/12... It's just arbitrary, so don't let it confuse you.

Comparing motors isn't easy or simple. In fact, comparing motors to figure out which is "more powerful" is really a lost cause because you can literally MAKE any motor more powerful than another by adjusting battery voltage and/or prop size. Find motors that will do the job, then compare using other means, like quality, price, support, etc..
