xl would be best. 3665 or 3674 and anything from 1800kv to 2370kv would be best. 2200-2370 would get you the best speed outta your Nimh or 2 x 2s(4s) pack.

Ive ran the HW motor in my E Revo and Maxx and it was a decent motor for the price. Never a problem. The Tacon would prob. be a much better motor thou.
Tht ESC will never be Restocked. Its been discontinued. Check Kershaw Designs. He has a Leapord Hobby 150A that is this same ESC rebadged for $100.
Do not buy his "own brand" KD onesd. They are QUIK 100A ESCs and there known to fail. They can be bought on EBAY as aeolion for $35 and Hobbyking as HK brand and there garbage
