Sorry to hear about you loosing a nice plane. I have been flying for over 35 years and have seen many planes lost due to radio problems. I have yet to see any planes replaced by the radio manufacturer but I am sure that it has happened. From what I have seen Hitec has been great about taking responsibility for problems and working on a free fix faster than anyone that I have seen. Years ago I had an expensive Proline radio that crashed plane after plane, it was sent back to Proline many times at my cost for labor and shipping and it never was fixed. I just cut my losses and put it in the trash. Hitec is fixing the problems for free and you don't even have to send the radio back most of the time!
