cheap esc

jshalcott:
i'm going to use a cheap esc. would a 40 amp esc be ok for a 12-18 volt motor

Admin:
That depends specifically on the motor and the application. :P

Check the motor datasheet and see what the current draw is on it. If you are lucky, the datasheet will give a chart that compares torque vs current vs voltage.

From experience, 40A will probably be fine.

Try not to use motors above 12V because finding good/small batteries starts to become difficult.

jshalcott:
thanks, the 50 amp one is a little bit more money so i think i'll go with that just to be safe.
thanks

Remember that everyone doesnt know what an esc is, as a side note

If someone doesn't know what it is, they can't really help him with his question, so who cares?
