Default Is it overweight?

Hi Guys,
I have just finished buliding or maybe better put the finishing of a Thunder Tiger ARF Cub but would still say a good 8 to 10 hours have been put into it, very enjoyable hours I will say,

I have done an electric conversion on it and have a question on weight,

Its total weight has come up above the weights stated in the manual,
The manual speaks of weights between 3 and 3.5 kgs and my finished plane with 4 cell lipo installed weighs 4.1 kg,
I have set up the COG perfectly but the fact it weighs heavier than the manual has spiked my question,
I have set it up with the most "nose heavy" COG being a learner so added some lead to the firewall after mounting the battery as far forward as practical,
Its suggested COG was 4 to 4.5 inches from leading edge so I set it at 4,
Somebody told me that sometimes the weights are a bit missleading in the manuals,

Will the extra 600 grams be a problem?
I cranked it up testing roped around the fuse and tailplane to the TV cabinet and gut feel tells me she wants to fly,
I just hope she isnt too heavy???

Cheers,Paul
