Stronger driveline for the flux ?

[JThiessen]

Did you by chance inspect your truck for a seized bearing when you took it apart last time? Based on the last three threads you have done about your Flux - all had the same theme. And you have stated that you dont do a lot of big jumps.
There are usually only 5 causes causes of driveline failure of this type:
1) Landing big jumps on power
2) Backflips on high traction surface (pavement or grass)
3) Hard side impact that would compress/flex the a-arms enough to cause the steel to break.
4) Manufacturing defect
5) Overpowered driveline

You have ruled out #1 previously, dont know about #2,#3. #4 is a possibility, but it sounds like you have broken the same parts twice. #5 should be ruled out - there are too many of us that run ours hard on 6S and have not experienced anything close to what you have. The only other thing I could think of is possibly a seized up bearing - but I would think it would have been an obvious thing to cause that damage.

If what you are saying is factual, maybe get it fixed, and make a video of you driving it until it fails (since it always breaks within 3/4 of a pack).
