At least 50% of the post upgrade flight time with no video (No Signal in Red on app) iOS 8.3 on iPhone 6 with 2.6 GB available 1. Upgraded the Go app only after deleting previous version 2. No other apps active 3. Airplane mode on 4. Channel 19 or 20 tried in auto and in custom mode No indication (other than lack of video) of limited video signal strength. (Full bars). 5. Tried 2 new cables (apple compliant) 6. Tried new micro sd card 7. Doesn't matter if close or far the video is intermittent. More off than on. 8. All other telemetry is stable and accurate in app (radar, Dist, height etc). Had no issues prior to upgrading from pilot app to first Go version. Got that sorted with a new cable now this. Any ideas?
