First FAiL with the Carson 8T Tamiya Euro-Cup Brushless System and the Tamiya DT-02 Sand Viper! This Tamiya DT-01-02-03 Buggy series was going too well I think, with six previous problem free speed tests, so maybe it was just about time something else happened.

I tried out another NiMH battery after this test, but with the same results, so I will spare you for that video. I also tried out a 2S LiPo with the same result, so the NiMH wasn't the problem. And then just before giving up I tried out a last battery, another 2S LiPo, and the motor/ESC suddenly worked for 3-4 minutes! Watch that video and pleasant surprise here: https://youtu.be/lUoPIlEejZQ

The 41 kph (approx. 25 mph) in this video is of course NOT full speed. The short explanation is that the motor/ESC kept activating some kind of cut-off or protection system. I've had this one out running in the spring and summer off road without any trouble at all. But not on this day. The plan is of course to get it fixed somehow, and then also try it out with a 3S LiPo.

Anybody knows what is going on? Help would be appreciated.

Here it is running on a 7.2v 3600 mah 6S NiMH Battery with full Tamiya ball bearings, Tamiya 19T Steel Pinion and an 8T Carson Dragster 3 Tamiya Euro-Cup Sensorless Brushless Motor (stock is ball bearings, 17T alloy pinion and a 27T brushed silver can). The Louise E-Rocket Street Rear Tires are fitted for this test (no gear ratio change).
