Just kiddin' droves of helpfull info comes from here.. I have the Q500 fully modded out, the 4k now the H. The 4 k was sent back for a GPS glitch then then it was lost at Yuneec for 2.5 months. Funny right? They made good and sent me a new one. Now as far as the H goes, it went in for a repair after one motor would shut down in mid flight. Scary as hell! I guess i'll get over having the crap scared out of me everytime I send up the H but then again after reading the issues everyone is having after doing the up dates (which I have done)scares the crap out of me...The beast still gets my heart a pumpin'. I do love Yuneec and their customer service. So sorry Yuneec,but I ordered the new Mavic from DJI - just sayin'
