i did see a physically similar motor on ebay, but it was rated 24v @ 250 watts, guessed it was not what you had used.
in my case i have a standard C5, 'Behemoth' which has the original C5Alive 24v upgrade, obviously the pod is not used and the old sinclair controller was removed.
while it all sems ok to me, no real idea what punishment it has had, so i'm expecting likely as it is the original motor and gearbox might not last over long, me being the proactive type i'm just looking ahead for alternatives in the future.
like you, i'm time poor and have loads of ideas buzzing around my head to try out - and a brand new as yet unused MIG welder to play with, and just begging to be plugged in
so your design in either format is very attractive
. as i Karl's new metal gearbox when it comes on line, will be interesting to see which one is the quicker or more robust - having seen the prototype at Brooklands hard call to make a guess on, but either will improve the C5's reliability.
