Hello all. I fly a quad X4 with a KK2.1, no GPS, and Turnigy 30a ESCs. So, today I was flying it around (Autolevel WAS on, battery was 100% charged), and all of the sudden, the motors go dead silent. It was only for about 1/3 of a second, but was scary nonetheless. It dropped about 2 feet, and then recovered. So, keep on flying, and it does it again, but for a longer amount of time. I get scared, land, pull out the battery, restart, and then lift off gain. No change. It stalls again, but for a very short amount of time. "I can deal with this, I think" and keep flying. I go 50-100 feet up, hover a bit, test an aux servo, move around a bit, hover again, and then it stalls, but this time for almost 2 seconds. It wakes up again about 10 feet above the ground, breaking its fall, but still crashing it. This is really bad. Again, the motors would go silent during these "stalls". Anybody know if this is a KK2.1 issue, and if so, what can I do? If not, what could it be, because this is a serious risk for ANY flying. I really need some help with this. Thanks.
EDIT: I did not hear an ESC beep (signature of my quad starting up), so it probably wasn't a battery issue.
