i recently bought a jato 3.3 used. It was running not great but ok. i took it to my local hobby shop (hobbytown usa) and the guy there tuned it and it was running amazing. id never seen it do wheelies before :P. The day after that i went to run it and it was bogging down a little but not to bad. It was running anything like it was at the hobby shop. So the day after that i took it to a local dirt track. I couldnt keep it running! It would bog down so bad out of the corners. This is my first nitro and i dont know anything about them. I didnt think it could be as easy as a tuning issue because it was just tuned? Sorry for the long read any and all help would be much appreciated.
