read what their warranty's say in the manual,most only insure the radio equipment.i would try to get in touch with a supervisor or write a good formal letter to them it wont hurt i have had good results this way.this is similar but was with a hard drive,my friend had one burn out he was a very excitable type.he sent a nasty gram to WD and the reply he got back was he was blocked form their web sight .honey catches more fly's than vinegar.......lol.i am very tenacious at getting hold of the right person at these places don't give up with just one persons answer,there is always someone else they work for that will listen...sorry for your loss that is always disheartening to lose an airplane...good luck
