So a BEC or something similar isn't needed?

You would only need to add that if the car is stuttering or cutting out. That noise has nothing to do with the BEC. It is just the digital motor in the servo trying to nudge the wheels over the last little bit. It should stop making the noise if you pick the front tires off the ground.

Actually what is happening is known as a brown out. Those Savox servos draw alot of juice. Couple that with the fact that your running a Castle ESC which is known for having sub par BEC. 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.

I tried the RCshox 2 stage pistons for the first time at my last race, I ran 32.5 front and 30 rear with standard blue springs.
I run on a UK outdoor bumpy track, I tried using big bore shocks before as I needed more pack for the bumps and jumps but was never happy. 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

Ive searched and been reading this thread for awhile, but maybe someone can help me out with my setup.
Mamba Monster ESC
CC 3800 w/fan
15t pinion
Ive only raced twice with this setup and each qualifier and mains it seemed the motor was hotter than normal. No issues with it while its running, just when Im done it seemed the motor was too hot. 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.

hi guys. my scte is on its way from 1hobbies. do you guys prefer the tekin pro4 motors or the tekin 550 sc motors? ill be running on a very large outdoor loamy track. if its been asked already, can you point me in the direction for the posts.
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?

That is pretty agressive gearing for that motor. Dropping down the CL to 80% really will not hurt performance but will help with motor temps as it gets rid of amp spikes that just translate into motor heat. 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.

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.

Also, what pinion are you running and should i snag up a couple when i order 1 so i have different sizes or should i stick to one and change limiter settings on the esc rather than pinions?
05-22-2012, 06:19 PM
are you running the 4000 or 4600? I too will be running this set-up and excited to get it running as i converted my 810 to the SCTE but just waiting for a few last parts and funds...

I run my punch setting at 5 with a 12 tooth pinion. Make sure and get some high capacity batteries though (6000<). The tenshock motors will lay waste to my turnigy nano-tec 6600's in about 8 min.

awesome...ya, i was looking at Losi's site and see they run from like 12-18t mod1 pinions so i'll order them once im ready. Selling my slash 4x4 to finish up the scte conversion and selling the nitro stuff off my 810 to help along so this will be my only baby so i wanna get it right the first time...
