    Angry Tmaxx running BAD need help

    Got a tmaxx 3.3 used.. it doesn't want to get up and go.. if you punch the throttle it bogs.. if you slowly pull the trigger it goes good. I can tune it so Ithat takes off decent but as soon as it hits 2nd gear it leans way out.

    Buying used is usually getting someone's jerry-rigged headache; with nitro you can expect the engine to be done. Bad running engine could be a bad tune, air leak or an engine needing replacement/rebuild. Air should enter only through the air filter and exit through the exhaust pipe. Anywhere else and it will cause a poor performing engine.

    +1 on Double G's suggestion. If no leaks found follow the tuning bible....

    I could say GG-rigged but that usually turns out perfect.

    I noticed some oil being flung out around the flywheel
