weyant - try turning the motor temp cut off setting up like mentioned before. the rotor generates more heat internally than you can measure on the outside of the can. So it you set it at 190, the motor is probably only going to read 130-140 on the can. so there is room to work with. I generally set mine up at 230 or disable and measure with a temp gun.

Ultimately if your not happy with it or worried about it, send it to us and we will verify it is working as expected.

thanks for all the help with this prob. I have made the recommended changes and hope to get to the track this week to test. if the prob is still going on I will contact you and start the steps for a checkup. unlike the other viper systems I have this esc was bought used 5 months ago and the motor was bought new 1 month ago.

We tried resetting but the VPort isn't doing anything. No lights and it will not shut the esc down. My local hobby shop is sending it back. Thanks for the help. The big problem is we have a points race this weekend and I'm in second so far.....oh well I will just have to make it up later in the year..

I've got a used (perfectly functional) VTX10r I'd sell for $95 shipped and I'm in PA so you'd have it in a day or two if you're interested. Love Viper but I'm getting out of SCT and into eBuggy...VTX8 on the way.

I just noticed that you offered a military purchase program. Our exchange server is down right now so I cant email from our .mil account. Could I email you from my personal account with a copy of my military ID and stateside drivers license or something like that? It shouldnt be down long but we're going into a long weekend so who knows.

Yes when you send the email in just include a copy of your military ID and they will get you all set up with the discount!!!! Thank you for serving as we get ready for this July 4th Holiday!!!!

Would be a good gearing and settings in the ESC for the sc10 with a vst17.5 on a 100x60 clay indoor track?

I start at 75-26 and work from there. I have gone as high as 29 and low as 24 depending on track and layout. Always check your temps. And see what the lap time differences are. Make sure the timing on the can is turned up to about 45*

Add instant punch -- gain a couple of tenths per lap!! Pro9 (1/8) and Pro6 Cap boards available now at www.shopviperrc.com

With my driving skill, is it nessasary?is there any other benifit from it? I like the pic of the other item there.

All depends on if you think you can use it. If you have a jump on your track that you just can't quite clear --- this will help.

I'm also doing some of the testing with the Pro9 and I will say that my ESC is running cooler and I'm seeing longer run times. With the longer run times, the 'drop off' comes later in the pack.

WooHoo my VTX8 just landed. Can't wait to get this thing installed...one week running a HW ESC was more than enough.

You'll love it. Let me know if you have any questions.

My VTX8 has been stellar since I've owned it. I just took third place behind a couple of sponsored stud muffins in 4x4 short course with an SCTE 1.0 and a 4000kV Tekin Pro4. I have not changed anything on the ESC since my very first programming. It's been smooth and pretty much flawless.
