Hi Anwar,
I observed that when my battery comes little bit drained then glitches will start to be seen and have read a lot about the PPM. They say that glitches are always observed to this type of receivers (Rx) but they also mentioned about FERRITE Ring. Ferrite, as I know is used to filter some "NOISE". What can you say about this? Is this a good and a cheap solution for the glitches?

Regards,
Fernie

Ferrite rings are typically used in electric helis, to reduce interference from the ESC and electric motor.  It may help in your nitro situation also.

The important thing is to get your antenna routed away from the rest of the electric stuff.

Hi, Already did what we had discussed in the field but still having some glitches. I think this is normal to a PPM Rx. Let me see after replacing my Rx with the PCM if I will still have those glitches.

Thanks & regards,
Fernie

Ideally, we should try to identify the root cause of the glitch.  The Align 2-in-1s are known to cause PPM glitches in some cases. 

That said, switching to PCM will mask small glitches.  Remember that it is not eliminating glitches, just masking them.  If the glitches grow bad, it may result in a lockout.  Hopefully, your situation is not one of those.
