Pretty much everybody I've seen who has experienced this type of incident complains of radio failure. Doh, in a stall/snap/spin like this, you're out of control and the radio naturally appears to be the culprit. Normal tendency is to add more opposite aileron and more back stick which only makes it worse (followed by a call of "I don't have it!"). Given sufficient altitude and anti-spin inputs, you'd be able to recover and we'd be back to the same situation that started this thread. That's an awfully coincidental glitch for an airplane that has had a history of snap/spin with normal elevator inputs.
