No it's not worth the money to have someone else do it for you,if your a newbee then yes it might be a good idea.Don't go by what traxxas says to do,do the heat cycle method.I don't feel like explanning it to you,go to nitro engines and read the heat cycle thread.It's easy to do and don't cost a thing.Use that 35 bucks for spare parts or more fuel.The heat cycle method is the proven way to break in a motor,traxxas's way is very old school.Take your time and you will have a solid motor.What motor did you go with a 2.5 or 3.3?If you went 3.3 make sure your not to lean or you will have a broken con rod in no time.
