Viper had just went into business when the VSE motors were released, and the only real problem was that we tested the motors with Team Drivers / Experienced Racers. Everything performed fine and we had good results. It is when the motors made it into the hands of those less experienced that there were overheating problems.

The failure came in a young company that didn't know you had to consider not everyone is a experienced racer. The motors ran well, and we have some team drivers who have run them week in and week out for over a year with no issues, it was the people that were new to R/C, or new to Brushless, that would start off with a guess on gearing and over-heat them.

Viper re-called the motors and refunded everyone's money, not because they were bad, but to make sure the customers were satisfied. Rather than point fingers / blame towards the users not being experienced enough, or just replace motors until people "were off warranty", Viper did the right thing. Give them their money back so they can go purchase what they needed.

It was a costly learning experience, but it has allowed for more time for R&D and engineering to make sure the product is not just a "racer's level" product. 1/8th electric is a class / market that is only popular in the US, and is a very small segment of that market, but Viper has committed to that market.

We are still testing, and doing the "un-thinkable" to these motors to prove them out. We've changed our testing procedures and thought process to more duplicate the whole market, not just the racers.

I have a Savox 1258 in my SCTE and have run Copperhead allot (R.51) and have had no issues with my radio system (Futaba 603 Receiver).

Some ESC's / Radio combinations experience problems with glitch and brown out issues, due to the BEC not having enough amp capacity that require to run a glitch capacitor / external BEC. In my opinion this tends to get the blame pinned on the ESC, or the servo, but it usually seems to be all relating around a particular radio brand.

Fortunately we have had no reports of those issues with any of the Viper ESCs irregardless of the radio system or receiver used.

I myself have 4 cars with Viper ESCs, all have Savox 1257 or 1258 servos and no issues.

Silv if you run it at seven and have your cutoff at 6.4 or what ever you have it set, when the pack goes so does everything else. I run mine at 6.0 and never had a problem with it.

I'm looking at replacing my LRP's and see 2 versions of the VTX10. I understand that the R has no motor limit, but does it "feel" different on the track?

aprilliamille - I ran 86/23 with a 9.5 last year, maybe 24-25 depending on track with a 10.5. Don't forget to check temps when you start out to help verify.
