On your startup with the DD, when do you call it a good startup? When you can punch it and get instant acceleration every time? I will post pics this evening of my build, seems that it will always start up but the tire size has a lot to do with how fast I can roll into the throttle.

Instant Acceleration from WOT at any speed is the goal. With the 80amp ESC, I feel like the surge might have been overtaxing. WOT would squeel at anything less than about 5 to 10mph. I know the 80amp ESC was being pushed to it's limits, since If I ran HARD, it would thermal.

Tonight I'm going to install the Monster Pro 125 amp ESC with a 2700uf Cap rated at 25 volts. This is Novak's pick of Caps, so I'm thinking it will be enough.

I got some thermal compound for the base of the ESC. This will insure a really good thermal exchange with the Aluminum Mount.

One thing I noticed with the 80amp ESC, if I had the wheel turned and tried to start from a dead stop, it didn't like that for some reason. Voltage drop from the internal BEC being loaded? Well that's gonna be a thing of the past too. I will install the 10 amp CC BEC as well. This will also remove ESC heat added by the internal BEC.

I also found a neat little micro toggle switch at Radio Shack that I think I will put on the ESC for on/off.

I plan to shorten the motor/esc wires and use the connectors that came with the Monster Pro. They are alot bigger. 5mm I believe and have a higher amp rating.

In light of the problems that plaque the Mamba Max setup, I'm sure the 4mm connectors are barely holding their own in this setup. In fact, if there is any internal arcing going on inside motor connectors, this will make it cog as well.
