Wow thanks for all the replies. I am looking for speeds in the 45-50mph range for daily bashing but would like the ability to "kick it up a notch" when my neighbor takes out his 3.3 Revo. :017: I currently have a new 6 cell IB4200wc pack that I will continue to run and have not yet decided on what battery setup to get for the new setup. I will get either a 4 cell IB4200 pack that I can wire in series with my current pack or a 3s 6000mah or 8000mah MaxAmps lipo pack.:032: I ordered the MM today from my LHS and it should be here by Wednesday or Thursday. I am going to order the batteries in a day or two once I make up my mind. And does anybody have some gearing suggestions to start with?? Thanks!!
