Rustler XL5 + CC MM7700 + IB4200 6C = 45.8 MPH

[RPC Werx]

I'm new to this forum, and just want to say thanks for all the info that could be found here- it's been very useful.

I was surprised at the speed and acceleration the Mamba Max 7700 provided with just 6 cells. The Rustler will flip on it's back like a turtle from a dead stop with full throttle, and do rolling wheelies at 30mph. All I have to say is, " It's all about the batteries". I've run some brand new Peak 3000mah batts(just to see for myself) and the performance is about 1/2 that of the IB 4200. It's night and day what a quality battery pack can do. With that speed and gearing, I'm roughly calculating that I'm getting about 1.06 volts per cell (49000rpm)at that amp draw, probably around 50-60 amps. Lipo,s would only make it better . Thanks again for the info this site provides, hope my info is useful as well.

My settings on the CC Mamba Max controller were:
Brake/Reverse:*Default
Brake amount:50%
Reverse amount:25%
Punch control:0% Disabled
Drag brake:0%
Start power: Low* (Default)
Motor timing:Normal*(Default)
Voltage cutoff:5.4V

Rustler XL5:
RPM carriers
Carrier bearings 5x11mm
Aluminum idler
Delrin input drive gear
IB 4200 6C (non matched)
Deans plugs
CC Mamba Max 7700
87T Spur gear/17T pinion

Hi Werks, glad you like the Max!

Any particular reason for the 5.4v cutoff? We normally run no cutoff on NiMH cells for best acceleration performance, BUT increasing it can give a measure of traction/wheelie control if that's what we want on a high traction surface.

Again - glad you like!

I'm glad I like the Max...I love the Max. I figured that the individual cell cutoff voltage for each cell was .9 volts? So I thought a 5.4 V cutoff would be good. Even with the 5.4V the Rustler will flip on it's back from a dead stop, and wheelies on command. Plus the batteries may like it more with that deep of current draw.
My son drives the car alot and we rotate some 3000mah batts in there too, and they don't like the current draw very much(very hot/poor acceleration) with no cutoff voltage. I'm still experimenting with it, that's one of the cool things about the system. You can make it whatever you want for your driving style,track conditions, or just personal preference. Great job with this line up of systems, they will be my "flavor of the week" for years to come.

He he he, another one bit by the Mamba!
