I flew my E3D plane by Gary Wright last Sunday and another club member was timing the flight duration. I had to come down when the battery lacked "oomph" (plane will not climb), just a few seconds short of 11 minutes. Both flights.
I have 2 packs of 3S3P, 1500 mAh, 11.1 V cells, Kokam. I'm trying to find out why my Li Poly batteries were nearly exhausted before their time.
The same plane was flown, running an AXI 12820/10 brushless motor with a 12-8 prop, on a 10 celled NiMH battery packs and it flew fine, getting about 7 minute flights with those. With lighter (10 oz. lighter) Li Poly batteries, the flights should be much longer than the
11 minutes.My friend who has been using the same battery configuration, motor, and same plane design, said he gets about 18 minute flights. I emailed him about the shorter times on both batteries, but he doesn't want to talk about it.
Have I provided enough info for anyone to explain?
