The 2028-1700Kv motor is available to those that are ready to take their extreme speed setups to the next level. With the success of the 1721-2400kv we went even bigger. With a larger diameter and length, it handles more power/wattage. This allows more torque and speed potential. It will just need to be geared differently as the kv is lower.

Ideal for running up to 8s LiPo in 1:8 and 1:7 scale vehicles, the mechanical design boasts a stainless-steel sleeve to reinforce and strengthen the rotor for high RPM operation. Coupled with a massive 8mm stainless steel motor shaft, 8.0mm bullets and high strand, low resistance, silicone coated 8 gauge copper wire, the 2028-1700Kv will deliver massive power and maximum top end speed.

This is an extremely powerful motor designed for advanced and experienced users only. Below are suggestions for increasing your likelihood of success but it is not guaranteed. Start with very conservative gearing (small pinion/large spur). Check your data logs, temperatures and setup closely after each run to ensure you are not stressing components. This motor is intended for single passes only; allow time between runs for the ESC, batteries and motor to cool down to ambient temperatures. This motor can pull very high amperages. Make sure your batteries, connectors and soldering are capable of handling the loads. Inadequate power can cause poor performance and damage the batteries and/or ESC. Do NOT free rev the motor with no load, particularly when running 6s or higher. The RPM output of the motor is much higher with no load as the kv and battery voltages do not drop. Set ESC timing to Lowest (0). This motor will pull considerably more amperage as you increase timing. This does not necessarily equate to more speed as it puts more strain on the batteries and causes the voltage to sag. Less is more sometimes. Do not exceed 33.6v when using this motor. Be sure your pinion and motor bullets are secure before and after each run
