noob e-revo?

[rchotrodz]

well for now I am going to use everything stock until I see how it handles so stock exv esc and 12 cells so I don't think I would need the ubec unless I went to lipos correct? Also if I use the e-maxx trans can I still use the 2 speed or do i have to lock it in 1st or 2nd gear? I appreciate any and all the help I can get pics of where to dremmel out on the revo chassis would help if possible...
Thanks
