I haven't had the Typhoon H long, had a couple of minor issues with gimbal and landing gear, Was able to straighten those issues out with very little problem. Made a few flights did really well. I bought it used but in nice condition from a friend.Got 4 batteries with it. Late afternoon before last, I had just cycled all the batteries through the charger, all charged fine. I put one of the batteries in that I had not flown with before, when all booted up, showed 16.4 volts. Launched it to about 50', raised landing gear, then went to 115', flew it straight away for about 1500', got low battery warning, started it back, then it fell out of the sky, total flight time under one minute. Has anyone else had this happen ? Also, is there a reputable drone repair shop in the Waco or Fort Worth area. I'm located right in between. It flew awesome with the other 3 batteries, no issues.
