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.

Viper R/C VTX10 ESC & VST8.5 Brushless Motor Combo w/EZ Link (8.5T)
this is an awesome motor/esc combo. flat out. it in a 22 buggy, and with 10 percent boost, and 15 degrees on the motor there is nothing that can touch this thing in a straight line at my track. the power is super smooth and tractable, in a 2wd buggy on a slick track that says a lot. another thing i cant like enough is how smooth the braking is, i mean on a dime you can lock them up, but at the same time its very easy to just slow down and anything in between! overall i cant say enough good things about this system, the progauge is awesome, the motor and esc keeps cool, properly geared ive never seen the motor over 130 after 30 min on track.)

great at first. the combo page made it seem like it supported 3s lipo. IT DOES NOT. burned the motor and the esc. replaced because of my error. tried the new system with a 2s lipo and a capacitor blew within a few minutes. replaced capacitor, but the damn thing wouldn't turn on.)

i got my motor and esc, soldered the wires and went out to drive it in my slash vxl. after about 2 minutes, the esc shut off and woudnt turn back on. now my slash sits in the shed until i feel like spending another $160 for another esc. but when i fixed it, it was a blast to run around. it is super fast and lots of torque. i already blew about 3 tires on my slash with this motor.)

Have this in a SC10 2Wheel and it rips! Excellent customer service and easy to use. You cant beat having the ProGauge right there ready to dial in your set up. The 8.5 will spin the wheels for sure, went to 40% punch just to keep it from doing wheelies. This will keep you up front in the Mod class.)
