Default mSR dropping after 30 seconds

My Blade mSR started acting like the battery is dead after less then 30 seconds of flying. It isn't the battery because I've got 5 of them and they all do it with a full charge. I put them on the charger and it just blinks saying they are almost fully charged still.

What's happening is I fly for less then 30 seconds and the blue light goes out and the mSR start dropping like the batter is almost dead. Once it goes down and I let off the throttle the blue light comes back on and I can fly again for 15 seconds of so and the blue light goes out and it starts to drop.

I have had many batteries that act like yours, they were old and tired. (like me)

Mine also act like they take a full charge, but they won't deliver it.

Those batteries charge at 300 ma, but then have to put out 1.6 amps to fly the mSR
I put an amp-meter inline on my mSR to measure the true load.
As a battery ages or just decides to quit, there is a factor called internal resistance that starts to climb. If it wasn't for IR our batteries could deliver a unlimited current until they were discharged.
Batteries with a lower IR will have a higher C or amps, ability ( there are other factors involved in the final C rating)

After you fly for 30 seconds, that darn IR is dropping your output voltage, and the mSR lands, then after a little rest, the voltage comes back up a little and you can fly again probably for a shorter time.

I bought 10 batteries from HobbyKing, and they ALL did the same as yours, the originals were better. My best ones are 160ma from Hyperion, I have had flights over 8 minutes with them, and I think somehow the mSR flys smoother with them.

Try a new good battery like the Hyperion, and let me know what happens.
The mSR must be the toughest thing flying, I crashed mine about a 100 times trying to fly inside my house.

+1 for battery. if they are old or it you leave them charge all the time they will degrade.
