This case is current pending. Please contact our technical manager, Nick Malato (nick.malato@hobbyauthority-dist.com) to provide more info of your problem so we can possibly duplicate it. At this moment, this is not a warranty case.

Inspection #2: 7/30/2015

We tested the motor in a AE RC8.2E today with 4S and 16T pinion. The car ran full 12 minutes without showing any problem. After 12 mins running, the motor showed 136.1F temperature. Please see below photo This motor is not a warranty case after multiple tests on the bench and the actual chassis. We’d suspect the root cause was in customer’s ESC.

If the customer is willing to send us ESC, we will be glad to do more test on customer’s ESC + motor combination.

Please contact Nick.Malato@hobbyauthority-dist.com to arrange further testing or returning of the product.
