i broke my first nitro engine in by myself. as long as you follow the instructions you should be fine unless theres a defect in the engine from the start. at first its a little hard but as you go youll learn how to tune and get your engine running great. if you have someone do it for you take the time to sit with them and watch and learn. get hands on. the guy at my lhs showed me how to tune and get it running good and everyonce and a while ill go back and he'll check my tune and go over the truck and show me what to check and look for. most of the people ive met in this hobby love to help and talk to you about it. dont be afraid to ask if you dont know something. nitro trucks are a blast but there is alot of upkeep involved with them. theres nothing better than learning your truck.
