I have heard that about using pcm receivers. That it only masks the problem. I did every thing under the sun to figure mine out. And still couldnt get no better than a 70 ft or less range test with engine on and a real good 113yds off. Like I said before, I did all that gas engines required down to the last dot. When I range test it with this pcm it gets a good 150 or even up to 180 with the engine running full bore. And at least 300ft off.
