I am currently on the phone with Customer Service. For the most part I've always heard positive things about Yuneec's customer service. I can't say that I'm entirely impressed. I don't want to say they treated me like an idiot but.....yeah they did. If a screen blacks out and you lose telemetry 2-3 off the ground and it beats your bird up. Definitely not operator error. Anyone else have a less than positive review with Yuneec CS?
