It depends on how much packing tape you have used.
I`m guessing you have shoved some extra weight on the nose to protect it in a crash?
You need to get the battery further back or use a 1500 or 1600 mha depends on how much room you have.
Try to get it as near as possible and don`t be tempted to fly a badly balanced plane, it will end in tears.
Pop the battery hatch and take a picture and post it so we have an idea of your problem.

Nice plane! Like many have said, the proper cg for this plane is on the marks shown on the plan and you must shuffle components around (battery/esc/motor) to get the plane to balance on the listed CG marks. If your cg is forward of that mark, you have to move the battery back furthur until you get the plane to balance on those marks. If you can't get it that far back with a 2200 3s, you can use a smaller battery like a 1600 3s. either way, the cg Dave and Shannon have on the plan are where the proper flight characteristics come into play. FYI, when I build a plane, after I have the rough build done, I lay out the components like servos, motor, esc, etc until the plane balances on the plan's cg, then I mount them up. I always move servos as far forward as possible and use something like dubro micro control rods to connect servos to control surfaces. This way it gives you more flexibility with mounting stuff like battery and esc. In the end, having CG a little further forward is safer than a little further back! Good luck!
Think I may have found the problem
Put elevon servos in aileron position trying to be a smart cookie putting everything around CofG and centre of lift
Might have shot myself in the foot -- slightly
Out comes the wheel balance weights
