esc/motor question - can I use any ESC with any motor?


I have a Greatplanes Electrifly brushless motor (http://www3.towerhobbies.com/cgi-bin...1&I=LXLWX6&P=3) and a Eflite 40A brushless ESC. Is it OK to use that motor with my ESC? Or do I need the same brand motor/ESC?

Any brushless esc will work with any brushless motor. Making sure you have a large enough esc is another thing.

That ESC will work fine for that motor, as the motor is rated at 18A max and the ESC will handle up to 40A.

Yeah that ESC will work fine. If anything it's overkill. All you have to do is make sure that max current the motor can draw (in your case 18A) does not exceed the maximum amount of current your ESC can supply (40A).

Actually, the max current on that motor is 30 amps, and not 18. So the 40 amp ESC is a perfect fit...

I've heard claims from one or two flying buddies that they get better results with ESC and motor from the same manufacturer. But that has not been my experience at all - my experience is that a good ESC will work with any good motor, while a bad ESC will work only with some motors, if at all.

It makes sense too, there is actually very, very, very little difference between one brand of motor and another - they all use magnets and coils of wire spinning past the magnets. Only minor details differ. By contrast, while all ESC's do the same job, the software algorithms used internally may differ quite a bit from one ESC to another, and some are just plain better than others.

By the way, "bad ESC" doesn't necessarily mean "cheap ESC". I've been much happier with the performance of my cheap Suppo and inexpensive Turnigy ESC's than some of my much more expensive "premium brand made (mostly) in the USA" ESC's.

How about this: I bought a redcat Everest gen 7. Brushed motor, 2000mah nimh battery. Says Lipo ready. BUT, I I have an extra traxxas titan 550 12t brushed motor and an xl5 esc. Would that esc work in that receiver..?

ESCs and receivers are universally compatible so that should drop right in.

However, the truck's stock gearing might be set up for a lower Kv (i.e. higher turn count) motor - 20 turns is very common for 540 size stock motors - so you'll probably need to run the 12T with an appropriate pinion and keep a close eye on motor temperatures until you're sure the system is working safely.
