184g per pack so you should be fine with your packs weight wise.
Like i said when you get your kit and you have questions ask away picture tell 1000 words.. so be prepaired to so us your build..
Most of all enjoy the build and the wing it is one of the nicest wings i have ever flown.
Corrections, I got the weight wrong. Those nos are for the 3s pack. The weight for a 2s1p pack is about 260gram. So 4s1p would be 520gram. I checked the weight of PolyRC 4350 and those weighs about 250 per 2s1p. I am quite close with Kokam I supposed.
