Here is a Quote from Tekin Prez over at RC Tech:

Made it tougher for physical abuse like the Silver State track. Beefed up a connection we had seen fail more than once. The rule is once we note it, twice we fix it. We had seen that connection fail twice and one of them cost me my main in Vegas after some hard earned qualifying, so I truly understand the pain. Actually the only 2 failures we have seen in months except a wire breaking off. We are confident it is now as tough as it can be and it is ready for the real world.

The circuit is solid and able to handle more power than the batteries can provide as long as nothing cracks or literally breaks off the unit. Soldering of the wires is really our biggest concern. Losing any of the wires can be bad if is jumps over and welds to the next post
