Lipo weight?

[Raydee]

Guys what is the weight of the lipo's you are using in your 550's ? Just for the heck of it I strapped on two of my 4s packs that are 12oz each and man that heli was HEAVY. The 3s packs I was looking at are 9oz each so there isn't a huge weight diff. Now I am wondering if I should go 2500mah just to save the weight but give up flight time?

What about these cells? Might be worth a shot, I know they aren't the best BUT if they don't last I know the owner usually stands behind the product.
