New 1940 - 3 questions

[steve050773]

Just got my 1940 hi amp from Mike and I need some help before I start the install.

1 - the motor has three thick copper wires coming out of the back for connection to the ESC. Is this motor designed only for a direct solder connection? I also bought the 3.5mm connectors, however they don't seem big enough for the copper motor wires. I did a search on the board, and there seems to be a mixed opinion on direct solder vs plugs....

2 - Do I need to grind a flat spot on the shaft or can I just scuff the shaft so the grub screw has some grip?

3 - With a 51t spur, and UE 8 spyder diffs, what pinion should I start out with? I believe I have a 13, 14, 15 ,16 and 18 tooth mod1 pinion stockpile to pick from. I was just going to start in the middle with 15 and see what happens.

Thanks for your help.. I'll post pics when everything is up and running!
