Minor weight add ons is totally irrelevant in the model you mentioned especially if you have the power. To give you an idea, one of my 12 year old Giant foamy, used to be just under 2 kilo AUW on 5S/4Ah, now after all the Epoxy repairs with ~ 2700+ missions in the log book it's 2.5 kilos!!! I have noticed just a slight reduction in power during hovering torque rolls but otherwise no problems.
Higher C-rated batteries sort it all out, LOL.

It used to be under 2 kilo AUW dozen years ago.

Now at 2.5+ kg, note the discoloration of Epoxy after att these years.
