Never mind....I found a lot of info on the net that explains a lot of this. There's a series of HBFP videos on youtube from a guy that shows a complete drivetrain assembly....very handy to see how it all goes together...answered a lot of my questions.

Although.....I see most lipo mount mods seem to reverse the stock skids and use CF rods to build a support on the front to hold the battery. I heard a CP battery tray fits the HBFP in some way....anyone got a nice parts swap mod that could work? I may end up with superskids, so it may not matter.....

Thanks all!
