i just got my first nitro sedan-used-it came with a slightlly used o.s. .12tr. my question is how long or how many tanks of fuel before a rebuild? i only plan on parking lot bashing,no serious racing. are rebuild kits availible? or do you order stuff individually? how many rebuilds can you get before you have to replace the block? if someone could refer me to a website with such info or any other helpful tips, that would be great and i wouldnt have to waste peoples time asking stupid questions. thanks-sean

sean: I got my TR late in 2001 from Japan. I had been using it until end of 2003 summer. My worst estimate, I had about 8 gallons of fuel thru it. I have about 8 empty 2 gallon jugs of Blue thunder in my house, I was sharing fuel with my friend but I use it most.
It still have slight compression on it when I put it aside and start using novarossi engine

thanks, like i said i am new to nitro and i am getting a ntc3 with th o.s.12tr motor in it-it has about three quarts through it and i wasnt sure if i should tear it down right away or wait. i guess i will just run it for now

if you have time do a tear down and have some visual inspection. Just to make sure there are no funny business
