This is the Viper R/C Copperhead-R ESC & VX4R.51 5150kV 4-Pole 550 Sensorless Brushless Motor Combo. The Copperhead ESC is small and offers the smallest foot print to power ratio of all the speed controls currently on the market. The Copperhead can be used in 2WD applications with VX4 4-Pole motors, but has been optimized to perform the best with VX4R 550 class 4-Pole motors in 4WD short course trucks. It comes preloaded with 5 factory preset profiles, allowing you to easily select the profile for your driving conditions, from high speed to just learning. Plus, the Copperhead features ProGauge programmability so you can easily change the parameters of the speed control to suit your needs. Additionally, all Copperhead ESC's have factory installed high capacity bullet connectors, providing easy installation and removal for cleaning and maintenance.

The VX4R 550 4-Pole Brushless motors are designed to make maximum power and torque! With the substantial weight of Pro 4 trucks you need a motor that can handle the punishment that the class is known for. The Viper VX4R.51 has been designed and tested in 4wd Short Course trucks, and has been proven to deliver the 'crazy' power you are looking for with the reliability you demand. Plus, the combo is complimented by Viper's 180 day limited manufacturers warranty for peace of mind.

***EDIT*** This system was great at first. Enormous power. Loved it in my Slash 4x4 as well as my Stampede 4x4. But now my 2nd ESC died on me for no reason and I think the quality is just crap. Not built to last.

Viper R/C Copperhead-R ESC & VX4R.51 4-Pole 550 Sensorless Brushless Motor Combo (5150kV)
So far so good! I matched this up with my Losi SCTE, And have had no issues with not having enough power! If anything I've had to turn it down a bit for my track. Cogging is virtually non existent, And it's pretty smooth! I have run about 20 packs through it, and have had no issues so far. At first it would get a bit warm, but after switching to a 13T pinion, it has been fine (with still plenty of power). The best part of this combo is the price!! With the 10% off I actually got two of these combos (for a spare) and was still $100 cheaper than one Tekin combo!!

great system for the money and super smooth. Most the time I forget it's a un-sensored system

Viper R/C Copperhead-R ESC & VX4R.51 4-Pole 550 Sensorless Brushless Motor Combo (5150kV)
This set up is great - when it works. I went through several ESCs. Warranty support is good. It would go to program mode and you could not get it back out. It would not run. Never really got the problem figured out. I dont like the way the wiring is attached to this motor. The rubber boot is very soft. It does not hold the wiring in place going into the can. One of my motor leads actually frayed and broke right as I set my truck on the track for a main. I was revving it up to check controls and pop, smoke - dead. Couldnt race. It had been running like crap for several packs. It had also been losing power for several runs and finally broke. I took it apart trimmed and soldered back up the frayed connection and it ran like a champ for a while. Then it just started cogging and doing weird stuff. I dont have time to mess with my stuff. I want to be able to tune and race. Not fiddle with sketchy parts and have to throw in a back up at the last minute.

Viper R/C Copperhead-R ESC & VX4R.51 4-Pole 550 Sensorless Brushless Motor Combo (5150kV)
Been running this for a couple weeks in my son's Helion Dominus 4x4 SCT. I had a Castle Sidewinder SCT in there before, which was good... This combo bumps it up to... insane! Seems like Viper has finally got the kinks worked out of their mfg process - certainly had this on back order for a long time. The fit and finish on the whole thing is like a work of art. The brakes aren't as smooth feeling as the Castle, but I think there is some sort of anti-lock pulsing going on there... on the Castle I could lock the tires and slide (in a 4x4), however the Viper seems to brake it quicker, without locking, even doing a bit of a nose wheelie due to the speed of it. From full-speed (which is about 45mph according to telemetry), the truck will stop in less than 10 ft. Temp-wise, nothing even gets warm. ESC is 98/99°F and motor has never been over 110°F - I'm running a 13t pinion, so I may experiment and take it up a tooth or two to see what THAT's like! Overall, I'm very satisfied, and I'd definitely buy another. Maybe once I get my SCTE! Thanks A Main! --Dan

Viper R/C Copperhead-R ESC & VX4R.51 4-Pole 550 Sensorless Brushless Motor Combo (5150kV)
worst system i have ever purchased, gave this company a shot and had nothing but issues, first the rotor decided to un-glue itself from the magnet with less than a pack ran through the system (and this all happened during a race), and dealing with customer service the worst.. would not recommend this to anyone just stick to the name brand stuff and you will be fine ..... ended up getting a ballistic 550 4.5 with a havoc pro sc ran 6 packs through this already and its money..... just my 2 cents...

Viper R/C Copperhead-R ESC & VX4R.51 4-Pole 550 Sensorless Brushless Motor Combo (5150kV)
Very smooth system! Runs cool, easy to set up (especially with pro gauge) and the price is right. I'm running this with 14 tooth pinion in losi scte and its wicked fast. Most guys wouldn't run this high of kv in a 4wd short course but I figured why not? Now I can run on the local 8th scale track if I want or just use the pro gauge to lower the throttle end point to run on smaller tracks. Viper did well with the vx4r, it includes the double sided foam tape for the speed control and switch, and the esc wires are just long enough to reach the receiver box on my scte in a neat fashion (under battery tray).

Viper R/C Copperhead-R ESC & VX4R.51 4-Pole 550 Sensorless Brushless Motor Combo (5150kV)
This system is on and off, i am on my second combo and i already need a new replacement after running the motor for one day. i probably have spent more money on getting these shipped back and forth then what i have paid for the actual system. i am afraid of having the same issues with the lower kv motors such as the 4500 ones. overall, not very happy with it at all!

I am not happy with this system. I sent it back for replacement 2 times now, and I have only had about 5 minutes actual run time on all the systems they sent me. I am in the process of sending back their third system. All this is costing me more money than if I had spent a little more on a better system.
