2028 - 1700KV
BEFORE PURCHASING - PLEASE READ ALL DISCLAIMERS REGARDING WARRANTY AND PRODUCT USE WARNINGS ABOUT THIS PRODUCT.
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.
Please read all product use statements and disclaimers before purchasing and installing this motor.
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.
WARRANTY: Castle products are backed by the industry's best service and support. This motor is balanced and tested during manufacture and is warranted free from defects in materials and workmanship for 30 days following the original date of purchase. Due to the abusive nature of speed run setups, Castle is not liable for incidental or consequential damages to other equipment such as ESCs and batteries when using this motor and is not responsible for failures resulting from abuse, improper installation, misapplication or alteration.
WARNING: Speed run setups are inherently abusive and extremely hard on all electronic components. Every component in the configuration can be strained, weakened (or worse) without using extreme caution, observance of electric theory and advanced knowledge of all aspects of the RC hobby. High speed runs and drag racing are the most advanced, aggressive and volatile applications in the RC car hobby. Improper setup or use of this product can result in catastrophic failures of the motor, ESC and/or batteries. We’ve outlined important product use information below; following these guidelines will significantly reduce failures and increase your happiness and excitement. If you have any questions, just give us a call; we have real people right here in the USA ready to help you get the most (as safely as possible) from your setup.

Tech Notes: |
Water resistant design. The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant; water can cause signal loss which could result in loss of sensored capabilities. We recommend applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to this document for running and maintaining motors in wet environments. |
