[PSUBS-MAILIST] Motor Question

[James Frankland via Personal_Submersibles]

Thanks again all for the advice.

I'll have a look for brushless ones.  That seems like a good idea.

@ Alec.  Thanks for the offer of the motors.  Do you know what they are?  I
need 4 so i'd have to get a couple more.  I would prefer all the same.  I
can see if they would be suitable for me and if i can get any similar.

I shall keep researching for now.
Regards
James
