Over the past two days we've had a problem with our new Typhoon H losing throttle control with the ST16 controller. The firmware is all up to date per Yuneec web page support. Both times it was almost a near disaster. Lucky, some how the aircraft descended but, we had to hold the throttle stick in the downward position for several minutes waiting of the craft to respond to the throttle input. It seems like it took forever for the aircraft to finally to lower enough so we could grab it out of the sky. Not fun! I'm just glad we didn't have a fly away or worse a crash. Let us know if you've had the same experience and how you corrected the problem. I will contact Yuneec tech support tomorrow for help!
