The Cap is on the bench being built, not at the field. The big gasser pilot's at the field recommended that I use a PCM, they fly the BIG gasser 96 to 120 inch with DA-150's. The inside of their Fuse looks like an electronic store, very intimidating to say the least. Any way, putting things in perspective, my Cap is much smaller and will be set up for sport flying (not 3Ding). I didn't think it was necessary to jump on a PCM when I have not had any problems yet. I do agree that any bad RF should be fixed and not masked by the PCM as mentioned by Bubbagates, makes sense to me. The guys at the field are great guys and really know their stuff when it comes to the big one, I'm just don't think my Cap is in their class and needs the very top of the line equipment....I'd like to keep it simple, safe and enjoyable for me.
