Going to build a BL Baja, few questions..

[JAILBIRD]

I just ordered a Baja 5b SS kit with the intent to make it brushless. I know some guys here have done the conversion. I'm going to use the RCM kit and a CC 2028/XL2 combo. I'm wondering if there are any "must do" hop ups I need to order before I start building. Also, does anyone have any idea what kind of cash I can get for the engine? I'm planning to sell off what I don't need to fund part of the build. Thanks for any help!
