Be aware that brushless motors don't answer quite so quickly to reverse commands as their brushed equivalents. They have to be stopped first then restarted the other way, so there is a slight (and I do mean slight) delay.

The brushless ESC I linked to in an earlier post is reversible.

My quick answer is Yes, you will need to make sure the brushless ESC does reverse.

OK, now, this will be the $5000.00 question. I use both port and starboard motors independantly to help steer this thing and turn it around. Can a brushless motor go forward and reverse?

Does the speed make much difference to a model submarine? It's a log in the water at best.

If the difference was a within 500RPM I'd say no, but with more than 50% increase RPM, it will make a big difference. Depending on the props and/or gearing being run, the motors may bog down and overheat, and as Albion pointed out draw a lot more current. It would be an excellent motor for converting an old 3.0 SD to 12 volt operation though as the RPM matches up very well with the 7.2v speed 400.

yeah, more amps

AH! I guess I'll get Mr. M to do his amp stall test on these new motors, so we have a definite amperage result on them.

(Something I forgot to get done)

Going by the specification (17500RPM at 12 volts) that motor is a different wind to the MFA version which is 12000RPM at 12 volts. I don't know how those two compare in specification with the Graupner motor.

We have a new selection of motors. These are already fitted with suppressors.

I mentioned before that the 12 volt speed 400 long can motors are no longer available from Graupner but they still offer the 7.2 volt 400s.

MFA sell the 12 volt 5 pole 385 motors, if that's of any help.
