You're welcome. I have seen people in this thread talking about running a sensorless copperhead setup in 4x4 short course, but I haven't done it so I'll let one of the 4x4 guys answer that.

That would be your least expensive option, but again, sensorless.

A couple of guys where I race really like their Copperhead setups. Other than that, I don't drive 4x4 SCT, so I can't really offer to much info on it.

I run the Copperhead R esc and the 4500kv motor in my 4x4 sct. Love it. Plenty of power, and cold as ice. It temps out around 120 after an 8 minute main geared for more top end.

oh ok i uesd to run the 1/8 esc for sct 4x4

I tested one of the 1st copperhead systems before they came out and I was really impressed, especially for the price

wait sorry if this has been said before but when will the biper 1/8th esc come out and how much?

there no date yet i ask all ready

Thanks for all the answer guys, appreciate it!!

VTX8 is on its way -- waiting for delivery. This thing is going to be the ultimate beast - 1/8 scale (3s-6s), 550 2 pole (2s), 4 pole (2s) -- great tuning options, built in fan, all metal case - including fan guard. You guys are going to love it.

In regards to the VTX10 series applications:

The VTX10 and VTX10-BE are spec'd down to 6.5 motors on 2s batteries in 2wd applications. If your application is any more aggressive than that in ANY way (either more motor or 4wd) one needs to go to the VTX10R or VTX10R-BE

Now, the Red ESC vs the Black (BE) ESC, is the BE has the larger capacitor setup (more aggressive braking, more punch ) and runs a little cooler as the ESC case is not filled with epoxy to be water-resistant.

The BE is really the best fit for the highest demand applications, it does however sacrifice the water-resistant feature that the Red ESC has.

I thought that the B.E was still water resistant just not waterproof like the normal one (red one)

Well one cannot call either "water-proof" to the point that you can submerge it completely and pull the trigger and pull 200+Amps thru it. Depending on what is in the water the current can jump right across the terminals and short the ESC. And would not be covered under any warranty. There is no claim on the Viper website or in the manual of any of the ESCs for their level of "water-proofness"

Now, the Red ESC is "Very" water resistant. It is the most water resistant ESC in the market in my opinion. Our local Nitro series here in Minnesota has a 2wd SCT class and being they are Nitro events, they do not stop the program unless there is lightning. I have had to run several times in total down-pours with mud and DEEP puddles (think 1/8 nitro truggy 30 minute mains) and the old VTX10 pulls thru fine while the ESCs from others give up.

To me, if you have to run in the rain and had to pick a ESC, then the Red ESC would be the best in the market in my opinion to run. But I myself understand that electronics and water don't play well together and I am taking that into consideration that if I choose to and it fails, it is my fault.

thats hard core man! i dont know if its worth all that...

Yeah, his esc was fine, but the truck was ruined, lol.

I didn't like it, but points are points.

Replaced the bearings, rebuild the shocks, and clean everything good.

In nitro they don't stop for the rain. Even at the 1/10th iFmar Electric On-Road Worlds this summer they were running outdoor and it rained during qualifying. They kept running.

Here is a video from the Wisconsin Nitro Series, fast forward to about the 5:00 mark and that is the conditions I am talking about. There is actually a whole science and tricks for running in the mud (slick tires is the #1 most important one)

lol, I did that about 10+ years ago. We ran in the rain for the RC Pro series on red clay. So much clay stuck to my 8th scale that it stopped moving. When I pulled it off, it had 15 lbs of clay in/on it. That dirt you ran on seemed to hold up ok.
