I have the same model, twin 120mm Stumax fans. Twin Yep 180 amp ESC. S.
My all up weight is 20.6 kg. Mainly because I chose to use 12s11,000mah per fan.
She handles the weight just fine. Mind you I don't think I would want to dump it.

Didn't know SM was making 120mm fans? Might be helpful to the OP if you posted up some photos of the setup and inside showing how you did your ESC, its a VERY expensive kit and one most don't want to make mistakes on!
