This is inexcusable. This problem appears to be popping up everywhere, with 8 channel receivers too. http://www.runryder.com/helicopter/t427916p1/

I sold all my PCM equipment, and now I'm stuck with stuff that won't work this summer. I live in the desert at high altitude. The sun here BAKES! Even when it is 60 degrees, if you are in the sun, it feels like 90. When it gets to 90 real temp, the sun is almost unbearable, but the old equipment worked. Futaba needs to make new receivers, and offer a free exchange program - AND DO IT FASST!!!!!!!!!!!!!!!!!
