If you have EPA settings on you're radio, you can run a Blue Bird 620MG. A little slow, but great torque. I have one steering a G2R revo and have no problems, also have one on my 3.3 revo.
Work because i gotta, play because i wanna
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise
