Can a brushless motor run in reverse?

I've got a Tower Pro motor, and would like to use it on a flying wing, but am unsure if I can wire the three leads in reverse to make it work. Thanks in advance.

By "change the wires around", he means swap any two wires to reverse the motor.

Yes but I usually don't notice it until after I've made it a nightmare to get to the motor wires.

Or use a CC ESC (and maybe others?) that can reverse the motor direction from the ESC programming mode.

Me too - I seem to always forget to run the motor until the cowl is on with all those itty bitty screws, or I've glued it on such as on one of the foamys.

Which is one of the things I love about the Castle ESCs - just hook up the handy dandy CastleLink and tell it to reverse the motor.

I would like to add to the question. Is it possible to make a dualsky brushless motor run on channel 4 in both directions on the fly. ie: can a robbe ESC instruct the motor to rotate left on left stick and right on right stick? Local shops here say it cant be done. Our application is a thrust motor on a large airship.

Plane controllers don't have the reverse you're looking for, boat controllers (all?) have one.

ESC whether brushed or brushless, will go up in smoke.
This goes for all electronics in general, servo, RC, tv, appliances, car etc.

You will be your LHS will be and your wife will be


Finally, my devious mind has figured out why some ESC manufacters don't tell how to reverse rotation
Or am I just being paranoid?

thanks ron,
but could it be possible that you blow up the battery instead because i accidently did swap the wires and the battery blew up? i tested the esc and motor and they seem fine.

I'm trying to make a twin engine plane (Like a Bomber) all I know is if you change two wires from the esc to the motor it will spin the other direction. But where do I get a proppeller for the motor spinning backwards?

Same place you get all your propellers...just ask for a pusher prop. THey are available but there's not the same range made as standard props.
