GREAT! Ran this system in my SC10RS w/ 20T/48. Fastest truck at the track. No problems with it. Just getting back into the hobby so I wasn't comfortable with spending alot of money but with this type of performance, i really don't see why people do. Key to this hobby>>>>>RESEARCH FIRST!

Bought this based on all previous reviews to install in my RC10 B4. Ran 3S and 2S and this combo is pretty amazing. Buggy is pretty insane running 2S, 3S it had to be screaming over 60MPH on road 3S was way too much for the track. ESC and motor are very well made and pretty sexy looking as well. Great job, Viper!

Way too much power for my Rustler, and i love it! Super easy to setup and change modes. Only thing i don't like about the system, i'm destroying my Bodies with no wheelie bar. It's a true Torque Monster.

My first thought of this combo was hfs the power was grate the brakes were ok and for only 100$ you will not beat it I would recommend this to any one. This was a perfect fit for my sc10 truck. The only thing I don't like about this combo is that it's loud so if u by this don't be alarmed it fine you will not regret buying the setup best bang for the buck you will find. It's good for the track and grate for bashing it has no temp problems on 2s lipos

william king - Rating: 5 of 5 Stars! Verified Owner Tuesday, June 19, 2012
Excellent product I installed it as a replacement for my velinon system that went bad on a 2wd slash. with the 23 tooth pinion and 3s lipo its unbelievably fast. And has excellent brakes much more precise than the velinon which always wanted to lock up on hard stops. On the stock gearing I can balance the truck on two wheels until I run out of road. Great price for a great system. Had one Small issue with setup the polarity was reversed on the motor simply swapping only two wires to the esc fi[More…]

This was my first after market motor and esc other than Traxxas stuff. I was really impressed after I got my radio adjusted correctly. I put it in my new B5, the esc is a little big for this buggy but it fits with a little cramming. Other than that it performs really good, almost to much power for the track I run on. I would recommend this to anyone on a budget build like I was.
luke mickell - Rating: 5 of 5 Stars! Tuesday, December 03, 2013
this is by far one of the best systems i ever had way better than the traxxas vxl system this this makes my rustler flip onto its roof with a 8.4 V nimh battery pack and with a 3s i had no tires left it is an awesome system i would recommend it to any one who wants to go brushless or has a traxxas vxl system
Daniel - Rating: 5 of 5 Stars! Friday, October 25, 2013
Bought this as a cheap BL system for my Traxxas Rustler and was very pleased with the performance. Previous comments about noise are spot on and my Rusty whines like crazy but its very fast and stays very cool even after hard bashing sessions in loose gravel. I don't have a GPS or radar to track my speed but if I had to estimate how fast it is on 2s with stock gearing, I'd say in the 45mph range. Set up is easy, and for the money the overall build quality is fantastic. It is sensorless so th[More…]

This combo is very very fast...ran a 6500mah straight and this thing is ice cold ...my son and I ran this with big smiles on our faces....for $99 this viper combo is solid and screams quality ...I still have to hook it up to the programmer and I am sure it will make this combo even better
Russell KOTZUR - Rating: 5 of 5 Stars! Verified Owner Monday, April 29, 2013
Works great in xxx sct, in fact had to turn throttle epa down because it was too fast for my skills at full speed.
Chris Elson - Rating: 5 of 5 Stars! Verified Owner Sunday, March 31, 2013
Very strong and worth the money. I put it in my son's torment and its smoking fast only on the 2nd esc setting. I'd definitely buy another viper.
Dustin Hamilton - Rating: 5 of 5 Stars! Wednesday, May 16, 2012
This combo is bad a**!! Run's just about as smooth as a sensored system. Buy it, try it, love it!!
Lilwal - Rating: 5 of 5 Stars! Verified Owner Saturday, August 17, 2013
I have to date run this system for about 2 hours run time. Took out brushed system put this in, kept everything the same and hit the dirt....power compared to old system was enough to blow a tyre......it was great!(although some down time putting tyres back on) ESC is large and just fits into SC10 where the ESC goes, but I mounted mine on top of the battery tray with some zip ties to even weight out a little. ESC is easy to use even without programming card, but I will get one at some stage to f[More…]

Performance on 3s was quite poor, tested in a Savage XS on the same gearing I tried this system (3900kv 4 pole) back to back with the traxxas Velineon (3500kv 2 pole). The traxxas system had more punch, more torque and a higher top speed. The brakes in the copperhead are aweful as well, unless you have the tuning gauge you cant get enough brakes, the first 4 profiles all had poor brakes and if you like to pulse the brakes on and off the copperhead thinks you want reverse and will trow it int[More…]
