I have two large mapping frames that have Black Cubes in them. They both were running 3.9 firmware and flying well. I completely erased both and installed the Rover firmware to get rid of 3.9 and installed Plane 4.0.9 as a new install. Both of these planes have flown several hours without a problem with the previous firmware. These planes are big and I need both hands to launch so I use Auto Takeoff with a short loop in Auto mode before taking control. After setup and calibration, I flew both of these planes to tune and on take off, both planes climb to 100 feet and start to dive. I can put both planes in FBWA and they fly level at half throttle. I have tried to recalibrate level with no luck.
A third plane that was changed over to 4.0.9 at the same time is running an older Blue Cube. This plane doesn’t have the same issue.
