The 3000 pack will be a considerable weight for that plane to carry around and I would just stick with the 2100 pack and never use the 3000. The 2100 will give you lots of flight time and it keeps the plane flying well. I think the extra oz. will affect the flying characteristics so much that you would not enjoy it. Try it and see if you would like, but I'd just stick the 2100's. If you do decide to try the 3000, let us know how it flies.
