Compatibility Notice:
- Transmission: Compatible with 1/18 TRX4M, 1/18 Redcat Ascent18 transmissions, not compatible with 370 transmission.
- Radio system: Not compatible with the stock TRX4M(or Ascent18) radio. Requires a new transmitter and receiver (with CH2).
Note:
- Some noise at mid-throttle is normal for the 1721 motor due to its high-speed, open-rotor design. This does not indicate a defect.

The 1721 Purple Viper is best for rigs under 700g. For heavier rigs, we recommend the 2204 Fat Viper for stronger drag brake performance.
