Without more info like what receiver and how it's wired to the cc3d it's hard to be sure what to recommend.
The helipal website says R9D receiver but that can run either PWM or s.bus. If there's only around 3 wires hooked up from the cc3d to the receiver it's probably s.bus, if there are more like 6+ it's probably PWM.
If you went through the wizard it asked PWM, PPM, etc... It defaults to PWM. You might try s.bus and see if it's configured that way.
One of the websites says the R9D led color indicates mode, red = PWM, blue = s.bus.
