Nice one matt, interesting

That's What I was talking about....
Now someone please tell me that Matt's post isn't better than any website figures

Thank you Matt, they aren't Heavy at all, I am now seriously interested in these packs.

Can we have an update on how these packs are doing? Im in the market to get 4x 5000 for my goblin and was going to try them out?

Flew these pre production packs today in Spunky and logged the results.

Still producing awesome power and enough to push Spunky to 137mph. Packs are still solid and showing zero signs of puffing. IR's are still around 1.4 - 1.8. Cells balance perfectly well to and drain evenly. They are performing every bit as good as the production packs I have to.

See the log.
