Although I agree my driving style puts a lot of strain on the truck, the Flux and MMM still have some design flaws:
1) The MMM installation in the Flux is too weak.
Double sided tape + 1 nylon strap does not hold for long enough (especially when the rear shock tower bends too much). I tried several types of double sided tape with no luck.
Actually my mod with a second nylon strap perpendicular to the stock one works very well. The reason it failed on that particular crash is that I cut the excess strap too close to the "buckle". I now have the same setup but cut an inch away from the buckle and it works great. No more ESC moving.
I'm still having a plan to buy the Traxxas E-Revo BL mounting hardware for MMM and use it along with a new plate to the Flux stock one. To be investigated.
2) The routing of the wires from the MMM PCB to the fan is stupid
The wire just scrubs against the edge of the PCB and insulation goes away.
Since I've replaced with thicker wires, I hope this will reduce the issue.
3) Direct soldering of RX and switch wires is also stupid
These wires can be exposed to serious strain, and in case of failure, you have to resolder them (something not anybody can do) or worse if the soldering pad is gone.
I'd rather have some good outside connectors, like ezRun does.

As you say, the mount in the flux leaves alot to be desired, but that is HPI's fault, not CC. Unless you want to toss the flux you will have to improve on the mount...
The fan and signal wiring is not that great. I detailed how to re-route both and mod the case to allow some shrink tubing to be placed over the signal and switch wires to help with the rubbing and add so strain relief. You should also secure all signal wires to the chassis solidly and leave some slack to allow for component/chassis flex. Anyone who has built a kit should know this by now...
Like anything else made these days you can improve/modify the design. That is part of the fun in this hobby, personalizing the truck to fit your needs and wants.
