Jammin X1-CR HV conversion

This is very useful information. It is making me wonder if I shouldn't rather get a smaller motor like a Neu 1910 or 1907 to save weight. I have not yet ordered one because Neu don't have stock of the 1912 I requested.

On the other hand, a 1912 might be big enough to not need cooling...

Thank you for posting your data.

I agree with you about batteries, but I've heard there are race segments here that last 30 minutes. It would be a big plus to be able to run non stop for 30 minutes in those races. Talk about nitro spanking. :)

I think I got my spur sorted out. Ended up redrilling it myself and managed to get it mounted more accurately with my $70 drill press. It's now a couple 100th's out instead of a few 10th's! Should mesh ok like this.

Unfortunately the countersink screws can't go more flush than they are. Hardened steel is very difficult to cut.
