This is the Viper R/C VTX10R Combo Package, with an included 8.5 Turn "VST" Brushless Motor and EZ Link programming card. Viperís VTX10R electronic speed controller for 1/10 and 1/12-scale RC cars and trucks gives you more features and innovations to make your on-road and off-road RC cars not only ready to run, but ready to compete! The revolutionary V-PORT interface allows you to easily manipulate your ESC settings via the included VIPER EZ Link without unplugging the receiver connector. The small footprint allows for a variety of mounting options, while the waterproof aluminum case provides maximum durability.

Viper R/C VST series sensored brushless motors offer smooth and efficient performance, durability, versatility and quality. The VST series motors feature a re-buildable design and high precision ball bearings for superior performance, and long life. Plus, five optional tuning rotors offer a wide range of tuning options, allowing you to get the most out of your motor. A precision machined 6061 T6 billet aluminum ribbed can is designed to provide the best protection and cooling, while the ultra low resistance, high current soldering tab system provides trouble free connections and easy wiring.

The EZ Link is the same size as a credit card, and is used for tuning the speed control while at the track without the need for a computer. The innovative V-Port on the VTX speed control allows for programmability without removing the speed control wire from the receiver. This means less wear over time and you never have to dig into your receiver to make an adjustment. All these features are complimented by Viper's 365 day limited manufacturers warranty on all electronics for peace of mind.

Engineered, built and tested to meet the needs of even the most demanding RC car applications, Viper R/C products have been proven to provide smooth and reliable performance for your RC car.

Viper R/C VTX10R ESC & VST8.5 Brushless Motor Combo w/EZ Link (8.5T)
We had great success with a VTX10 & VST10.5 combo in our first Durango DESC210R short course truck. The motor bearings lasted forever, and temps were always under control for the motor and esc both. As my oldest son advanced we ordered the VTX10R & VST8.5 combo for his Durango and passed on the 10.5 setup to my yougest for his 2wd SCT. The 8.5 makes really good power with conservative timing and temps.
Both of these systems have been rock solid for us, and the Pro Gauge makes things really easy to tune. We currently have five Viper ESCs in service at the moment. It's just one less thing to have to worry about on race day.)

Viper R/C VTX10R ESC & VST8.5 Brushless Motor Combo w/EZ Link (8.5T)
i have just purchased this system and boy is it fast. the progauge is extremely useful, takes a little getting use to at first but when you get the hang of it its not so bad. i would recommend this to someone who is in the racing scene for the price it is awsome and just as good as the higher dollar systems. i am currently using it for my b4.1.)

Viper R/C VTX10R ESC & VST8.5 Brushless Motor Combo w/EZ Link (8.5T)
i bought this system in october of 2011 i had only put 4 packs into it the motor never getting hotter than 140 the last pack i put on it (first pack of the day) it burnt up smoke billowing out of the car my gearing was not to high it was 21 pinion and 87 spur in a durango dex410, so when i sent it in to be warranted they said it was my fault and i over geared it and that the stator expanded and was rubbing the rotor witch is false based on the photos that they sent me. it has been over a month i have been fighting to get it replaced and they finally said the would send me a new one over a week and a half ago, i finally emailed them yesterday and they said i should have gotten a tracking # (i didn't) then they said they would look into it and i haven't heard anything yet.
