On this forum and a couple of others, some pilots have reported the left stick still works while the right does not during a flyaway of this type. In those cases the pilot was able to go max right stick with yaw to gain altitude and try to keep the H moving in a circle. Then turning off the GPS restored full control. If there is a warning on the screen you have to clear it by pressing the return button under the screen to get to the GPS menu. Many of these returned to Yuneec have had the compass module, GPS module or both replaced.
