    drive shaft end keeps popping off

    ok when i was at the track a couple of days ago i broke a half shaft on the inner side on the passenger side. i replaced with a new one and after that it popped off 3 times in 2 hours. its not breaking which confuses me. that was on an indoor clay track with stock tires. now i have a set of proline sniper tires to race on and with higher traction i might be popping it off more now. im running 2s lipo on 19/83 gearing. i have a zip tie on it thinking it might help and remove it before installing it. why does it keep popping off and not breaking.

    Sounds to me that maybe the ears on the shaft were flexed too much on installation. Maybe try a set of new 4x4 shafts to add a little strength. You know that little silver tool with a slot in it that came with your kit? It really makes installing driveshafts easy.

    Get some kind of different axle 4x4 hd is 6852x. The stock ones are garbage. Go to ebay.com type in slash tool kit or any other traxxas electric model for the tool.

    This is about my favorite upgrade: cheap and really does work.
