Hacker C50 Maxx

[widemouthmaxx]

First off thank you Mike for all your help via e-mail...I ordered the 9918 for my C50 maxx..which I'm not sure if I'll be happy with it. Everyone has the 9L and such..anyway..according to the hacker manual it recommeds the following,

Note:This motor requires the use of a Kimbrough 72T-32Pitch spur gear for proper operation.

...what are some gearing ideas I can use for both top and bottom end power?

Bottom end?

Mid end?

Top end?

..thanks
