Need info setup for Brushless Savage X SS

My setup at the moment is MM with 8xl 16t pinion and 47t metal spur with FLM BL kit for the savage all running on 40 series beadlocks and 4s of maxamps 5000mah. It performs very well with more power and speed than the nitro engine it had, but i am a balls to the walls guy so i am working on a MMM, Neu 1521 and 6s of Neu Energy.

Thank you.
I like balls to the wall myself as long as it is usable power. My 18b is completely stupid with power. Such that my stepsons stock AE18b will run right with it until the long straights and even then keeps up due to mine looses traction if the wind hits the throttle trigger.....like runnin it on ice. I digress. Sorry.
Can you explain, please, what difference this Neu 1521 will make over your current set-up?
I am curious to know if any of you have experienced tranny problems with all these high rpms and more than 5 times the power of stock? I predict having problems with the slipper clutch and the plastic case being able to hold the torque and any added heat.

Anyone who gives a setup uses the presumed 1521. I do not know these motors, I have confidence to those who believe to be the best motor ...!

I have had no problems with drive train. Make sure your diffs are shimmed correctly. That is the main reason they fall apart. If you shim them properly you should be fine.
I locked the slipper and made the start power of the Mamba at 50% (still plenty to make it wheely though.)
The Neu will give more torque because it can handle more volts for it is rated at 60000 RPM as apposed to 40000 RPM and because of the voltage increase it should result in in more torque and a little better top end because of the higher RPM capability.

The 8xl setup should outperform the picco .28 and the 1521 definitely will.

You have 4s on MambaMax? It's rated for 3s max???

Thanks a lot for your info!!

Yes you will just need to run a UBEC or a seperate rx battery. I run a seperate rx battery. Some have even had it on 6s but that is really pushing your luck and only runs for a very very short time and then thermals, but it does 4s just as good as 3s and runs 5s but sketchy at times. To run more than 3s you need to use castle link to disable the BEC doing this though make sure you have a separate LVC to monitor your lipos (i have a nomadio react w/ telemetry) so you dont bring them to low and damage them then remove the red wire from your throttle servo/channel wires going to your rx.
