If you didn't add fluid to your differentials when you got the car, shame on you. This forum is full of people telling everyone to check your diffs.( mine were almost dry)( I filled mine to about 1/8 in. from the top of the housing with 7000wt diff fluid) That would be first. Diff fluid is good as a basher for 15-20 hrs, racing should be every 3d - 4th race. IMO. Pull your wheels off and remove your axles to check your bearings. My wheels rolled ok, but upon inspection found them to have disintigrated. Literally, only the races were left!! Since every bearing in the car is the exact same, I would recommend buying enough replacements for all of them(16 total) that way when you check your diffs, you can replace the three in each of the diffs at the same time. I bought mine from VXB.COM. I ended up choosing the stainless over the chromoly because the stainless is rated for 39k rpm and the chromoly for 24k. Load ratings were the same. Kit number for the stainless is 8757 and for the chromoly ( which are actually stronger, 873 -thats 10 bearings to a kit and you will need 2 kits) For the 2200kv CC says the optimum operating temp is 150-160 degrees with a warning at 185 and above. Like so many have said before me, brushless motors are not capable to be run wide open for sustained periods of time with no intervals to cool down. I will run wide open for 10-12 minutes then cool the car down with some half throttle or less driving. When I change batteries, I let the car sit for 10 minutes to give the esc and motor a chance to temp down before going again. Someone else said(don't remember who) "driving your brushless full throttle all the time would be like driving your personal car with the gas floored everywhere you go, you are going to destroy your car." I hope that can at least give you a place to start. Yes, a busted ESC would definately cause the motors to die! I will look for your amperage draw on the cc1600kv motor. Most electronic parts say to allow for 30% in losses due to any number of things from guage of wire, length of wire, connectors, etc... The HW esc is rated at 150a continuous, with the 30% taken into account that would give you are real world operating range of 105A- 150A continuos. My CC 2200kv motor is 120A. Should work fine, but depending on the quality control the day your esc was produced, may be an issue? Do you have anyone close by to swap out your esc to try theirs"???
