FPV quadcopter HIGH ALTITUDE

with 2 4S 3300MAH BATTS, I quickly flew 200 feet in front of me then started a 3.5 min Climb at full throttle. I don't know How high I was, Im open to estimates. I know I was with the clouds. I have to put on the OSD and Then i'll refly and post DVR footage. my 1.2G 1.5W lawmate TX was perfectly clear, but the low light sucked in camera. The gopro saved the day as usual.
