traxxas tec-4 3.3
hey i just moved from electric to nitro and im planning on getting a used tec-4 3.3 rtr. i heard you have to do engine break ins, trimming and more maintenance. can anyone help me with this? how many times do you have to break into your engine? how do you trim and adjust leanness and richness of oil and how would you know its lean or not. im kinda confused.
