ok well i have a rustler and i have only ran one gallon through it and the engine is well was tuned then it started acting funky. So i called traxxas and they said to richen my LSN so i did still a no go. So when i go WOT it just barely accelerates,and bogs, but when i just barely pull the trigger its as if it want to fly but doesnt scream like it did two tanks ago. Also it Screams when first run it for the first 5-10 minutes but i followed break in and everything. Also it runs hot no matter what.
