This is what I'm running now. I am very new to this and unsure how fast these trucks are supposed to be. I like crawling, but i would like more speed than what I have now. What gear would you recommend I use? I am running 2s 5000 lipo. This is my first post and I haven't had an R/C for like 15 years, so I apologize if I should have posted somewhere else. Thank you!
