hi asgorath. can you pls. explain further "i took the body off and saw that part of the plastic that covers the body was missing thats what made the pop noise" i was a little bit lost. is it the body post parts? wherein you clip the body unto the txt? in any case. i rolled over my previous txt a lot of times, but never did i experience a popping/snapping part.

i also did the evx/titan combo on my txt before. and my set-up was stock gearing, 2-3000nimh and the unit is with stock bushings. though, the batteries are really warm to the touch, but never TOO hot. i have my motors clipped with heat sinks as well. try checking the mesh on your gearing. it might be a little too tight.

hope this helps. good luck.
