Build another truck. That is the easiest. It is real hard to have one truck to do all.
You build a truck for every thing you want to do and you have it covered. :)

i'll bash with with this one, then see bout the rest.

mamba max says on the side:
2~3S lipo
6~12 cells NI-MH
does this mean i could run 12 NI-MH's without seperate BEC?
thank you.

You might be able to. It also depends on the servo load. If you are running one lower power/speed servo, you should be ok.

However, I always recommend a UBEC over 3s or 8 cells. The ESC will just heat up more because of the BEC and that's the last thing you need. Think of it this way, running 4s on the built-in BEC with a 1A load will force the ESC to dissipate over 9 watts. That's really a lot.

ok, thank brian.
i will be running servo's of the digital kind with 8kg of torque or even better.
so i'll need the bec then.
i tested a motor of my truck(stocker) and on 7.2volt it only did 15k rpm.
so i'll be runnig 4s lipo or or 12 cells NI-MH anyway.
then it will do about 40~45kph.
thats good for me.

Your ESC will thank you. ESC temps will be lower too and that's a good thing! :027:

well something's off.
maybe its the bec.
the steering suddenly lost lots of torque.
my servo was a little warm.
will try other servo tomorrow.
will see then. hope its not the MM.
