RF module for spectrum?

[erhard52]

Hi Erhard,

There may be two problems happening here.

First, the power source may not be working properly.  The X10 manuals (both v1 and v2) both say that when the power supply goes from 4.01 to 4.5 volts the led will turn yellow.

Second, are you using S-FHSS in your 4in1 module?  If you were using FrSky D8 or D16 then the frame rates with those protocols are incompatible with SBUS and servo operation will be erratic.

thanks, right!
update (all good):
-servo works now on  x10 v1. i had to change the protocol to
MULTI FRSKY X D16 and turn telemetry OFF. before it was FrSky D8.
still the x10 LED turns yellow the moment i operate the servo

- also the turning to yellow LED was really due to low voltage - 
after replacing the battery LED stayed green. so X10 worked as advertised and is really sensitive to small voltage drops

GOOD NEWS: radiomaster receivers with SBUS work with XPS X10+ v1 and v2!

i just checked out that the Futaba S-FHSS protocol also works

thanks again
erhard

PS.: it still seems the v2 version is more robust because it worked fine in all modes whereas the v1 struggled in one

btw thanks for your continued very helpful input and
 Happy Easter
