Hi Frankie, I'm writing to you from Australia, while it is true that PCM is more expensive, if it saves just one plane, even a basic trainer, you are way in front fiancially. My girlfriend & I both fly with PCM, & we will not be going back to PPM, forget about failsafe, for a moment & think about a 40% increase in range, when range checking my girls trainer, which is a Mk1 Skyraider, by the way, she got about 40 good paces before any surface started to shake around. After I changed to a JR 770s PCM receiver she now gets at least 70 paces, with the arial down, & we have had no glitches at our field since, & we would know if we did because failsafe is set to reduce power to just above idle & give a small amount of up elevator & hold ailerons at neutral.
Good Luck & enjoy this fantastic sport.
