V2 dead at 61 hours of use. It died with a failed firmware update attempt going to V1.20. If said the attempt failed, but shows V1.20 is current when linked, and fails on any attempt to change firmware. It will not arm or even try to make tones. red led comes on very dim but power goes to the servo. When I opened the case I found the fan lead broken off the board too. Time to send it in for a V3!
