Hey Chief,
Bummer.
If it's any consolation; You haven't lost as many models with one radio as my father. He uses an extreme 2.4 conversion on a Futaba 9C. He has lost about 6 models in FL because of radio problems.
I finally got him to buy a new radio, so far, so good.
I wouldn't recommend staying with a radio too long based on repairs to it, especially since there are so many new radios available for a reasonable price.
Hope you're back in the air soon, with a good working radio.
Chris...
