S800 EVO over weight

[Jerry N]

Hello, was wondering if someone could tell me if being .33 kg overweight on my S800 EVO is going to be a big problem.... DJI says maximum take off weight is 8 kgs! My machine weighs 8.33 kg's. I am using 2 ThunderPower G8 7700 mAh 70C at 2.340 kg's Anyone know how much flight time I might get using only one battery? I have already purchased 4 7700's. Would hate to have to sell them or find something lighter. Anyway.....thanks in advance for your help Jerry
