When looking at data logs from racers we often find the batteries being used are simply not sufficient for the load the system is asking for. 1/8 on-road isn't going to work with 30c batteries and cheap connectors.
Care must be taken when choosing components for this genre of racing. It's a much higher load than 1/8 Off-road simply due to he grip the cars generate.
The most successful setup has been 6s and a 1900kv in most conditions. Where we see the most issues is classes/racers regulated to 4s. This forces guys to use 2650's(one of the nastiest loads around) and 4s batteries. These MUST be up to the task of supplying the esc with the power it needs to drive the motor. We see big power spikes and blown caps when cheaper and or less quality batteries being used in these conditions.
I find it interesting that you repeatedly like to point the finger at things like batteries etc, when a Trackstar 150A (rated LESS than an RX8) which costs a third the price, has three times the warranty, handles our GT "Nasty loads" just fine. I have seen more than one RX8 / RX8 Gen 2 fail at on road, as well as numerous IX8's, most people now run the Trackstar 150 or Xerun 150 as they have been the most reliable.
This finger pointing reminds me of Castle when their ESC's first started becoming unexplained fireballs (ie MMM and MMM V2, MMMXL, MMMXL V2 before they went to XL2) and it's disappointing.
Credit where it's due, the RS / RS Pro / RSX have been fine, the RX8 is fine in a 4wd SCT application, but in an application like 1/8 On Road which on paper should be fine, it fails, and fails badly. Most of us who race this class are very conscious of batteries, Internal Resistance is what I use, as soon as a packs resting IR is over 10moh a cell, it's out of there, your "Max Amps are often 5moh new, Trackstar Nanotech Ultimates are often under 3.
At the end of the day most people will judge a company on how they deal with issues regarding their products, do they look for something to blame or do they look after the consumer?
