It's pretty windy out and I just did two batteries. Forgot to time the first one but the second one gave me 11 minutes. My average flight times are between 10 - 15 minutes. Mine don't seem to last long at all. Also learnt a lesson in that when doing a range test fly into the wind! Not with the wind otherwise you'll be having kittens like me when it's down to 1 bar and still over the field struggling to fly home. Thought she was a goner. I did manage a 5000ft flight though according to the st16 which was impressive. What is the longest stock range someone has achieved?
