We replaced the stock motors in our Stampede and Blackfoot and sure enough the modified motors (Chamelion and Money motors) have not lasted very long at all and now need rebuilding. I am not about to buy a lathe and get into all of that so we are now looking at brushless - if it is maintenance free!

We are looking for reliability in the drive train etc (the Blackfoot has run stock without fault for two years) so a mild brushless setup would be ok. We also run GP3300 6 cells and IB4200 7 cell max, not lipos.

What would you guys recommend?

Much appreciated.

Rich

Whats the reason for not using the Mamba? I just watched a video on youtube of a guy using MM5700 and GP3300's?

Thanks.

With those batteries, don't even consider the Mamba Max.

With the Mamba Max you can set the voltage cutoff to the nearest tenth of a volt. For batteries like that you just set it to 5.0 - 5.4V and it runs fine. The tradeoff is maximum acceleration and braking vs. runtime and battery/ESC/motor heat. I have done this often and fine-tuned that number so I am speaking from experience. You don't really lose any runtime b'cos NIMH discharge is pretty flat and you are not going to get any useful life past 0.9V / cell anyways. This setting also prevents the stuttering you may see on other ESCs when applying too much power or accelerating too hard.

With any brushless you should replace the plastic idler gear with the metal one, just to be on the safe side.

The only downside of the mamba is the time you have to spend fine-tuning it, whereas the Novak is just a 'drop-in-and-go' system. The mamba might not do well with the default parameter settings, it sometimes takes several runs to get all the parameters set for optimum performance. Ultimately though mamba will end up better, or more configurable; it has a 'punch control' parameter that you can set to 10 to take it easy on your drivetrain, etc.

Thanks for the input.

thanks

Status: offline 		IMO your best bet would be the traxxas VXL brushless system because of the fact that the motor has only 3500kv which is great for beginers. The vxl esc also has a training mode were you can set up the esc to only allow 1/2 power at full speed.
And it only costs $169.

I may just go for that setup, thanks.

Actually I have tried this one and I wouldn't go with it just yet, it seems to be a real current hog and drain your batteries very fast, significantly faster than a properly set up mamba. The VXL definately has performance, but in terms of efficiency or tuneability, mamba max is only $10. more.

Where are they $10 more??!!

Status: offline 		If you want runtime, the SS4300 is your best choice. I prefer the Mamba system myself, but only with LiPo. There is the cogging issue with the MM on NiMh. You can't add speed AND runtime without better batteries.
