Ok, my Truggy Gurus......I am planning on running a Tekin RX8 with a 1350Kv motor on SMC 6V 4300mah. I always wanted to run 6V in my buggy but didn't because of ROAR. I do not plan on running ROAR with the Truggy. I hope this will be a good combination. What pinion do you guys recommend? The track I will be running , Thornhill, is the largest track in North America.
