Help! Tiny Tutor Battery Question

[DZFlyer]

Hello FliteTest Community,
I recently built an FT Mighty Mini Tiny Tutor (you can see build log here), and I was wondering if anyone knows how long the standard issue battery (2s 800mah 45c Tattu) should last on a flight. I am running the standard setup with Power Pack A and my Tiny Tutor weighs as specified on the FT site (248 grams). I am also running a 6x4.5 direct-drive CCW propeller on the motor (as recommended). I was also wondering whether I can check the voltage of my battery (using a voltage checker and the balance lead) while it is plugged in to the aiplane. If anyone can offer guidance, that would be much appreciated!

Yes, you can use a voltage checker while the plane is in the air.

Flight time depends on how hard you run the motor. If you are running full throttle the whole flight, expect 5-6 min or so. If you are just doing lazy circles, expect 8-10 min. I don't have any experience with your setup, so my guesses could be off a bit. After you have a bit of flight experience, you will be able to tell when to land by the way your plane flies. When it starts lacking power it's time to land.

Thank you so much!

I should add. The flight time I mentioned are for the summer time. Winter flying times are significancy (50%) shorter. Anything 50F or below will begin to shorten the flight time.
