Front and Rear Chassis Braces
Shock Caps
Front and Rear Shock Towers
Chris Pins and hardened washers

I've been using 1.6 front and 2.0 rear. My truck still seems a bit loose in the rear - I was over steering at the end of the long straight all weekend. Does this indicate too much steering or too little rear grip? Maybe I'll try a fatter front and thinner rear bar.

Here's my config:
- Castle Sidewinder SCT ESC/motor combo (new)
- Spektrum DX3s Tx with SR300 Rx (always used in my Traxxas Slash 4x4)
- Sävox 1258tg servo (new)
When I turn on I hear some beeps from the ESC/motor and everything is quiet.
From the moment I turn the wheel on the Tx, the servo makes some noise, just like there's some interference... I hope you understand what I'm trying to say?!
When turning the steering quickly from left to right, a few times after each other, sometimes the servo does some weird things and wants to go back in neutral position. All the time the servo makes noise.
Someone an idea?

So a BEC or something similar isn't needed?

Don't bother changing the shocks just the pistons, the RCshox 2 stage pistons are awesome they give better response in the bumpy sections and good pack for the jumps, I could corner so hard without rolling the tyres came off the rims!
Excellent job Marcus

Didn't temp it but not sure what to do. I thought of going down a tooth or two on pinion but not sure how much of a difference it would make. Also do you guys think it would be the ESC? Ive read everyone running the Mamba Max Pro, not the Mamba Monster, not sure if that has anything to do with it.
Thanks for the help

Do all the normal binding checks, wiring solid, etc.

also has anyone tried any other esc instead of the rx8? im looking at the hobbywing. i run the xerun's in my touring cars and wanted to keep the electrics in the same family.
thanks.

I'm running Orion r10pro with Novak 550 4.5 I want to upgrade to tekin pro4. 4600 do I need new firmware to make motor smooth or something?

Going back down to 15 with a little current limiter to limit wheel spin may be the ticket for you. Going up in gearing I am sure calmed down the bottom end on that motor for you to help make it more controllable. You can do this to an extent with CL settings as well and not have to run so agressive on the gearing.

When that servo tries to pull alot of current it will shut down for a brief moment and recenter itself. Your first remedy should be to try either a Novak or Spektrum capacitor. If that doesnt fix the problem you will need to run a CC 10a BEC. Personally I dont run Castles ESCs anymore for that exact reason. The RX8 with run anything you throw at it along with many other cheaper ESCs out there.
Does the problem happen when you suspend the car so that none of the wheels/tyres are touching the ground? It should be virtually silent. Then, with your hands off the transmitter (but everything on), start to turn the front wheels of the car so that the servo needs to resist your movements. This will make the servo draw current from the ESC. Apart from some humming from the servo, you should not get much glitching / twitching. If you do, it is because the BEC is overloaded and shutting down.
I used a Novak capacitor to fix this for my Mamba Max Pro, but a sure fire way to fix this for a couple more dollars (and some more soldering) is a separate BEC.
