Well i think we can see from the results of the poll which system people DONT trust!
1 vote for PPM .... ummm i bet that was Stigs!
No of fence Stig you have your views, and yes i remember our conversation, but since then i have had NO crashes due to lockout(only one before) i trust PCM, it works for me, and i would NEVER fly a jet with PPM, it would seem, is true for most jet pilots.
I don't know of any current, display pilots in the UK that fly PPM, and the truth is that if you go to a UK jet meet or public display, there are almost NO radio problems. I have flown when the sky has been full of planes, running 10kc spacing, (mostly Futaba). No problems!
Lat year we had a situation at the British Nationals, where a Jet on PCM reported 'holds' and landed. When he switched off, the monitor was checked and a solid signal was found on his frequency. It turned out to be some idiot that had brought a set of radio at a stand and 'tested' it in the car park! The key here is that the pilot was able to fly and control the model, land it safely without incident. I can tell you now, without fear, that if this had been standard PPM that model would have been in a bag! Or even worse, someone would be dead or in hospital. I can relate many stories over the years of similar situations.
One that sticks in my mind is a case at my local flying field where i was flying with another pilot, i was on Futaba, he was on Multiplex. He was on 76 i was on 77. I did a pass with 2 consecutive rolls, the model then did a 3rd on its own! Hold had kicked in, i throttled back and landed. when we checked, this guys tx was bleeding all over adjacent frequencies and Had to go back to the manufacturers.
I know , without PCM my plane would have been dead! These are just examples of problems i know about. How many times has PCM rejected crap, without me knowing?

I love it, and would fly nothing else, until a PROVEN better system is 'out there'.
