Sorry about your loss! I had four crashes on spectrum using the old software. All four were a result of "brown outs" or low voltage. I ened up testing a dozen receivers and it took them 2 to 13 seconds to re-establish the link to the transmitter. After the last crash I switched to a JR 9303 using the new Spectrum (JR) 921 receivers with the "qick connect" software. I have over 100 hours using this sytems on multiple planes and haven't had one issues. I use voltage regulators on all my planes too. The quick connect feature remains locked on the last two frequencies if it gets a power disruption and does not "re-boot" this prevents loosing the plane. </p>
