i hear some guys say that nitro requires lots of maintenence and upkeep and tuning i know not every nitro is like mine but i have an xtm xt2 with a 457 engine in it it easily has over 5 gallons of fuel through it and ive never had to mess with the needles however i did lean out the hsn 1/16 of a turn just because i could i run this car every weekend and if i can during the week since 2 yrs ago when i got it except when it was in need of new chassis parts because of the hard objects i hit its awesome not to have to tune it when i want to drive it but then i also have a tmaxx with the 3.3 that deffinently makes up for me not having to tune and mess sith the xt2 ive had brushed and brushless electric cars and boats to but now i only have nitro cars and boats and 2 gas boats fyi i am a firm beliver in after run oil every time you are done with nitro for the day if your interested theres a pic of my xt2 in my gallery
