RE: Edge540 26cc
I've not personally seen a Berg used in a gasser but I've heard that some folks have used them without problems.
However, I would not use anything other than a good PCM in a gaser.
DSP is a whole lot better than PPM/FM when it comes to interference rejection but PCM is a *lot* better at resisting high levels of RF noise and interference. What's more, it should always be remembered that the Berg receivers are only single-conversion and (despite what some say) this does make a *huge* difference when flying in a cluttered band like 72MHz.
Even if you're prepared to risk your model to a single-conversion PPM receiver you should stop and ask whether you're prepared to risk someone else's *life* to one? Big models (which gas-powered ones usually are) can kill. For an extra $50 I'd rather go PCM and get a little extra insurance.
