I would love to see you run a HC Rob. I've not ran a better setup than what I'm running now, ever, my berg didnt even make lines I make now. Pm'ing some info your way....
Thats the problem with reading, its not as truthful as the real thing :D People even blow up HR gears with all the other hop ups so nothings bullet proof really.
Brown showed up to my house about 2 hours ago too! But, it wasn't my XR10.... :-(
Are you building it stock or what Rob? Make sure you get the right screws in the right places so you dont have gears busting like other guys have.
