Buggy Weight?

Ok,
So, over the winter I have been modifying a Kyosho MP777 SP2. I began this modification before reading this website, so I can confidently say that the majority of people on this website will probably think I did everything wrong:
-Novak 4.5 motor
-dual battery trays
-center mounted (raised) motor
-maxamps batteries
-battery trays were made to fit the maxamp 10000mAh batteries.

Enough about my unpopular choices, I finally got the buggy together and everything installed and I weighed it today and the weight seemed a bit shocking...
without batteries it weights 7.4lbs (3.361kg).
Assuming I use the huge batteries I planned for, I would be at track weight of ~9.3 lbs
If I use 5000mAh batteries I would be around ~8.4 lbs.

I could probably trim some weight (~1/8 lbs, maybe a 1/4 lb if I went drastic).
So, how heavy is to heavy?
And what is the "average" weight of a buggy? (or just the weight of your buggy).

I will add some pictures for those interested later, I just got to work and I will have to wait till I get home.
Thanks
Charles
