Oh wow sorry to hear your troubles, it seems like Yuneec left out a whole lot of things when they made the manual for the H including a large section that should have been located near the end entitled Troubleshooting. Or even better if they decided to live host a copy of their H manual so that when people found that something could be missing from it they'd be able to comment & Yuneec in tern would be able to respond in the way of adding that issue with a fix into the troubleshooting area of the manual, that way instead of people just calling to get anwsers to issue & then having Yuneec only inform them of any possible fix, everyone that owned an H would be able to view the Q & A in the manual which would reduce the number of calls from people asking about the same issues.
