Konghead 4000kv EZ Run / Max 10

[BBB Spread]

I just wanted to give a review of the hobbywing 4000kv / Max 10 combo in the Konghead. The motors actually got quite a bit of power and given traction will actually pull a few wheelies in reverse. The motor and ESC on 2s never really get above 100 degrees which is rather nice especially because it was about 85 degrees outside today. 

Top speed on about a 30 yard dash was about 25 miles an hour which is plenty. This was done on the stock 18 tooth pinion. I'm going to try a few separate runs with the 20 tooth pinion, and then a separate run on 3s which I'll report back. Truthfully though the fact that you can pop wheelies on 2s in a 6x6 thoroughly impressed me. I'd also say that 3s may be a bit much given additional power would likely just create additional instability and make it a harder to drive.

As far as the ESC goes it is sensorless, and there was no cogging which is probably do to the low gearing on the Konghead itself. For the hundred bucks I paid which included the ESC program a card I'd say the combo was well worth it.

Okay.... So I ran it with a 3s 40c 4200 MH battery tonight and it ran about 34 miles an hour. Surprisingly it handled the speed very well for a 6x6 truck, but I credit a lot of that to the fact that I have oil-filled aluminum body shocks.

The ESC and the motor we're barely breaking a sweat. I know a lot of folks are Castle creation fans and I have to admit I like their products, but for the money these hobbywing set-ups are incredible.

By the way the batteries I use are hobbystar, and whether I'm running a 7600 MH or 4200 mAh I feel like I can run these things forever and I never seem to get below 7.5 volts. In other words at least for the 7600 MH I'm running the car pretty hard for about 45 minutes and I've still got life left.....I've never actually hit the cutoff.

I'll try it next weekend with a 20 tooth pinion and see where that gets me.
