Mine usually are in the range of 7 - 81/2". Just shift your battery around, I have been flying these with both a gws 350b gear and a 400a gear and they do fly great. I'm actually using a 7.4v nimh pack out of a Hobbyzone Supercub. So, your Stryker electronics if I understand anything about Strykers should make it a rocket.
Have fun these are great wings, and if you want a little spice check out the Kline Fogleman build thread lots of great ideas over there.
The zagnuts calculator was kinda fixed to the shape and sweep of the zagnuts.
I found these 2 calculators that lets you enter all the numbers for the dimensions to accurately calculate a CG for this wing shape.
I like the 2nd site better because it helps you decide what %MAC you should use.
At 20% MAC, it comes out to 7" (all around flying skills).
At 25% MAC, it comes out to 7.5" (for expert flyers).
I'll start with 7" and work from there...
Thanks for your reply...
