This is the Viper R/C VTX8 Sensored Brushless ESC and VF4.45 4-Pole Motor Combo, with an included EZ Link programming card. This combo combines the efficient control from the 1/8 and 1/10 scale capable VTX8 ESC with the raw power of the VF4 series power plant, designed specifically for 1/10 scale 4WD Short Course Trucks. On top of that, the combo adds in the EZ Link to make quick programming adjustments easy.

The Viper VTX8 ESC is more than just an upgraded VTX10, much more. The VTX8 was designed from the ground up to handle the punishment of the most demanding 1/8 scale and 4wd short course applications, with the durability to come back begging for more. Plus, the ability to operate on either 2S or 6S LiPo batteries, as well as sensored 2 pole, 4 pole and 6 pole motors from 540 up to 1/8 size from any manufacturer, and an adjustable BEC that can deliver 7V for your high voltage servos, makes the VTX8 an incredibly flexible system.

Combine this with waterproof construction, a full aluminum case and a fan with a carbon fiber brace that helps to efficiently dissipate heat, and you have an ESC that will propel your rig to the finish line and beyond, with reliability that your competitors can only dream of. These features make the VTX8 an excellent choice for high power applications when you need a reliable system, with virtually limitless programmability that does not require a PC.

VF4 Series Motor
Viper R/C VF4 Series motors take 4 pole motor power to the next level. With added durability, smooth efficient power band and stunning looks. Available in 2 sizes for 4wd Short Course - VF4.40 (4000kv) and VF4.45 (4500kv) designed to exclusively work on 2S batteries.

Quality craftsmanship, superior materials and a commitment to rigorous testing are at the heart of Viper R/C Solutions' product philosophy, so your VF motor not only gets you running but keeps delivering the power you need to get the most out of your RC car in even the most demanding conditions. Your VF4 motor's high precision CNC-machined 6061 T6 billet aluminum can is designed to provide the best protection and cooling, the ultra-low resistance high-current soldering tab system allows for trouble-free connections and easy wiring. Plus your VF4 motor is compatible with most ESCs on the market. For maximum performance match with Viper R/C's VTX8.
All these great features are complimented with a 180 day limited manufacturer warranty like all Viper R/C motors.

EZ Link
The included 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.
