Ersky9x (r218) doesn't work with UMX Radian

[JimO]

Servo response on my micro Radian is slow, jerky and with differential throws with a with hacked DX4e Spektrum module plugged into my 9xr Pro. The Radian servos respond smoothly with the same module plugged into the 9x with er9x. Protocol settings are correct. Any insight/solutions to the problem would be appreciated. Thanks.

Try switching the protocol to PPM, then checking the setting of "PPM Drive" is "full drive", then go back to the DSM protocol.

Mike, no change with PPM setting at " full drive". UMX throttle response is normal, and Orange rx's work fine with 9x and 9xrpro with hack module.

Correction, that should have read " .....work fine with 9xr and 9xrpro".

[MikeB]

So it is just the UMX Radian, with the hack module on the 9XR-PRO where the servos don't work properly, the throttle is OK?
The UMX with the same hack module on the 9XR is all OK?
Orange Rx's with the hack module on both are also OK?

That's right- it's only the UMX Radian (so far) with the 9xr Pro that does't work (except for throttle, which is OK). Module works fine in 9XR, JR XP9303 with other DSM2/DSMx rx's. (I don't have that many DSM2/DSMx rx's since the vast majority of my planes are on FrSky and older Assan). The DX4e hack was intended for Specktrum BNF.
