Product Picture

Product Features


R4EH-H, 2.4G 4channel receiver, FHSS. Use for Radiolink TX RC3S (Note: Cannot bind to RC4G).


1. FHSS anti-interference, better effect in performance. 

2. Top speed response, 12msonly, much better than others average 20ms .

3. True resolution2048, shake<0.5us ensures every servo act smooth and hold static.

4. Inverse insertion prevention. Wrong connect will be 0 in current, without any damage to receiver.

5.Control range covers 260 meters, and to be extended to 420meters.

6. Wide voltage input 4~10V, HV servo support.

7. Ergonomic design for easy assemble
