Scorpion opto 160 power issue

[Gaui-Deanoo]

Hi all I keep getting a red light one the way when flying... it kills the headspeed of alot on the model.


It's a goblin 700 with 24t pinion running 2200 with a 4525 520 ultimate

I have one set of packs that lasts a minute and 2 other packs that die of nearly instantly

Any ideas would be grand!
