Roll out was good and I was about 10' in the air on my climb out and boom. Rolled right and here comes the ground. I have sent the TX and all 3 RX's into Horizon and am waiting for their prognosis. I have flown all these planes with JR for a while and thank goodness I kept the old stuff. I am skeptical about 2.4 now but I have a buddy that has flying his in IMAC for over a year with no problems.
Were any of these models using y-harnesses? If they are amplified y harnesses that is your issue. There has been an advisory about not using these on DSM. They were designed for Z-PCM almost 20 years ago. Standard y harnesses do not cause the issue. Hope that helps.

Official word was "Inspected radio and found Chip to have an open causing partial writing of programming to memory. Replaced the system in the interest of customer service."

Thanks Horizon Hobby!

Cool. I understand the frustration of having to reprogram the aircraft. At least you will know the programming you are doing is staying in memory.......
