Radiolink's products NOT compatible with DUMBORC.
DUMBORC is the subsidiary of RadioLink, so the products keep the same FHSS spread spectrum of RC6GS V2/RC4GS V2/RC6GS/RC4GS.
While, RC6GS V2/RC4GS V2/RC6GS/RC4GS and receivers use the much higher specification chips, transmitter chip of STM32F103RB and the receiver chip as the industrial 32bits M0 because of the different market positioning.
So, all the transmitters from Radiolink cannot bind with receivers from DUMBORC and all the receivers from Radiolink cannot bind with transmitters from DUMBORC.
If any problems found when using DUMBORC products, you are very welcome to send email to us for tech support.
