Thank you for your suggestion greg. I'll look a bit closer on that setup.

Here are some of the motors I have seen mentioned in other threads with somewhat similar setups:

Hacker C50 series (mostly 13xl but also 12xl and 14xl)
AXI 5320 series (/28 or /14)
Actro 40-5 or 24-6
Plettenberg Xtra series (25,30)
Feigao Nemesis B50 13xl
Lehner 2250-12

If you have more info about any of these please feel free to share!
