hey guys!!the wife and i were out at the local park running our traxxas vehicles today. I think the 3.3 died in my wife's t-maxx and mine broke after 5 minutes in three different spots. the history... both of our trucks are over 10 years old. the t-maxx was wrecked hard and broke multiple parts (carb, suspension, chassis parts and the front bumper) before it was put up for a looooooong time. yes, i cleaned and oiled the engine and cleaned the rest of the truck up before moth balling it. i recently revived the maxx with new parts. fought air leaks with old rubber lines and tank seals so i replaced em. so finally got the maxx running like new again and got tired of being confined to our little street to run it so we went to the park. at first it sounded odd, can't really describe it but a red flag went up in my head. tweaked the tune a bit, thinking it was out a hair, and it sounded much better. ran about three and a half tanks of fuel thru it then the engine started to sound labored and lost power very suddenly. at full throttle the truck moves at walking speed at best. I've read these 3.3s are good for about 3 gallons of fuel before they crater. temps were about 220-230. blue smoke was consistant with a good tune. we took the body off to allow better airflow while running out in a soccer field area doing a lot of high speed runs to and fro. i went over the rubber parts looking for a airleak but found nothing obvious. trans and diffs move easily. being my wife has had this truck for such a long time i can't remember exactly how much fuel we have run thru it. it was broke in exactly as traxxas specified and i have always kept on top of the tune. any ideas? old plastic... my truck is also the same age(2.5r rustler) it runs for 5 min before something plastic breaks in the past 3 runs over very minor crashes. crashes that this thing used to shake off. my question here is do any of you guys have older trucks where the plastic seems to be brittle? I'm replacing the old rustler one part at a time and after today i was starting to think its not worth it. sorry for the long post. wanted to get all the info in. thanks in advance!!
