I can't seem to get the car tuned right. I sometimes get it running pretty good on top speed but its slugish on bottom end. Temp is around 240-250. Next time I start it the tune is WAY off and I have to start all over again. I have gone back to factory settings and started over about three times with no luck. Can anyone give me any advice on tunning ? also looking to change diff oil. 500k center 100k front 50k rear. Is that a good set up for the diff oil ?
 
as far as your first problem i would honestly say that you have an air leak somewhere (engine, carb, fuel tank, or even fuel lines) i would check all of those and replace your fuel lines with fresh ones and go from there. Now as far as your second problem, i wish i could help you but i don't have a clue as to what is a good set up for diff oils.
 
Diff oils... for racing? 30-50K in front, 10-30k in rear. Center use either 300 or 500K.
I used 30K in front, 300K in center, 10k in the rear on my racer. It would still pull the front end up if it hit a bump while I was on the throttle. I could give the truggies hell on tight small tracks.
I'd look at your fuel tank O-ring, notorious for leaking.
Be patient, that engine will take some time to loosen up and run properly. What fuel and plug do have in it?
 
I use Odonnell 20 % and an RB plug (dont know if its a hot or cold plug) recommended by my LHS. I have some new fuel line and a new 150cc tank that I haven't installed. I will install those and see if that helps. I did notice my main needle was loose but I tightened that up a few days ago. I really appreciate all your advice. I have changed everything I can get my hands on From A arms to wheels. If my fiance knew how much money I spend on my Truck she would kill me. I'm constantly up till 3-4 am in the garage working on something. I've spent so much money on that Revo and I can't get it to run as good and consistent as my cheap 200.00 RTR ofna ultra.
 
LOL right on will do any recommendations ? Odonnell ZO1T, Hotbodies, Losi, Mugen. ? (Hopefully my girl wont notice a new toy in the garage )

I have A Jammin X1, dead reliable truggy but a bit behind the times.
I'm in the market myself, undecided at this point. Maybe a Jammin X2...
You can never go wrong with a Mugen. The MBX5T still performs as good or better than most of the truggies out there. I have driven two, they made me want to sell my Jammin. The RC8T is another good one.
Losi's are not very reliable. Kyosho's are brittle.
I may give the new Z truggy from Z-Car a try, the buggy is proving very reliable, fast and super stable.
I'd love to get my hands on the O'Donnell's truggy, but the price! I'd be afraid of a parts shortage in my area too.....My brain is starting to hurt....too many choices, and as soon as I buy something, it's outdated!
