Ah, I follow Banx's truck on E-savage.com. It's a true out and out MT racer. He has the RB2 chassis though, it's quite a bit different to the RB3 (which incidentally, came before the RB2) The model designations don't indicate a progression, more just different code names for different projects. The RB2 is more aimed at being the ultimate E-savage chassis, rather than changing the truck completely like the RB3.
JSR: I plan to run both 4s and 3s, 3s for race, 4s for bashing. I plan on getting the CC/Neu 2650 for 4s running. If you are willing to part with that Medusa give me a private message with what you want for it, that motor is perfect for 3s running in this thing.
Yeah, I'm on E-sav.com, I'm lilredmachine on there. Reminds me, must post progress over there!
Tekin eh? I've heard much about them but never owned any of their stuff.
