My flight time seems to be getting rather low.
I am noticing that my battery dies pretty fast and dont know why.
With the standard battery I get about 2.40min continuous flight time ....nothing major just hovering and moving around.
With my other batteries (upgrade ones from Helipal - 350mAh) - only lasting between 2 and 2.30mins?
Is this normal and if not what is wrong?
I charge them using the stock charger and when they are charged all say 4.2v on my volt tester. When depleted say between 3.85 - 3.93v.
(overall only about 10 flights per battery at the most)
Not much flight time = not fun
