New DiscoPro build - Naza Lite on PPM/Sbus cabling - EzUhf on fw 1.43 - 5.8 600mwIRC off the Disco side pads ala step down board
While flying in GPS copter will suddenly level as though RC control is lost. Sticks are non-responsive. Switching to Atti/Gps and back and forth etc, has no effect. During the first event we were able to see rapid RED flashing LED. Similar speed as the Failsafe yellow but red. Copter seemed to regain stick control then immediately drop out again. At this point Cris was trying to regain full time stick control so dont know if it was in Atti or GPS when it decided to flyaway. You can see it accelerate slightly and head toward us nose in. At this point no stick control and needs a switch to manual to stop the flyaway. Guessing the throttle is pretty low as you can hear the esc's twitch, then drop out (likely throttle position) and the heli drops altitude quickly. Managing to get the heli flared and set it down in what looked like a pretty hard landing but actually wasn't bad considering.
So first couple seconds is the drop out, then the heli is non responsive - flight mode changes are non responsive with occasional twitches of stick, then no stick, during all of which the gimbal twitches and the esc's twitch a couple of times, then flyaway, then manual flick and esc twitch/flare/crash

*Video is from the first time it occurred. This was roughly 10-12 Batteries from Maiden. So this is new build.
*Have had the same problem even after moving the GPS/RX distance. The 5.8 tx is off the little Disco Holder so sticking straight up. The GPS was on a long mast, then a shorter mast and next test flight will have the puck hard mounted to the top plate. Don't "think" its a separation issue but keep moving the two farther from each other. (Note using 5.8 while waiting for 2.4 TX order to arrive) Have re-calibrated GPS (Naza Dance) at cow pie distances.
*Have had this happen now on three flights. Twice at one location and once at another. So its a copter issue not a location interference issue.
*Once it happens ONLY manual will give you sticks back.
GPS Dropout w Bad drop into Atti? Bad GPS Puck?? PPM Stream dropping out or not playing nice with Naza?? Bizarre ESC twitching through Core causing gimbal twitches and Naza conflict??????
Will drop puck to plate (naza dancing along the way), then reload/rebind ezuhf fw 1.43, then downgrade to ezuhf 1.41, then throw the puck away, then throw the naza lite away. Pretty sure I will have crashed at this point so not worried about further troubleshooting
Any ideas help very very much appreciated~!!~
