PPM and Gasoline with that kinda Ignition is sooner or later a unwanted Ground contact, PCM/2.4 is a solution, FM is prone to RF interferences, no matter what.
With my JR...PCM was not a solution...the PPM worked better. Some guys nicknamed the PCM as "programmed crash mode" I do like the New 2.4.....so far ! Capt,n
