Help! Help With First Wing Design

[Innaviation]

I have recently been working on a design for Flite Fest combat and was able to maiden my wing design. The basic structure of the wing is a box slightly larger than a FT power pack, which is designed to hold a power pack C with two FT spear wings on the side of the box.

Now here is the problem.

So I had my dad toss the wing and I just kinda let the wing stay on the same trajectory it was tossed at. So it flew fine until I start to put input into the controls, then as soon as I pitch up a little bit the nose of the plane gets shoved down and although it is possible to bring it back up and fly a very up and down flight I don't think this is how a plane works.

I have put thought into what the problem might be but I thought I would put it out here for any more advice.

You might have the control for the elevator reversed if you tried to go up then the nose went down.

That could be the case... to be clear when the elevator goes up the plane goes up, right?

I tried to design a plank plane once, and it had a similar pitch instability problem. After checking out the FT Goblin, I think my plane didn't work because I put the CG in the "normal" 25-35% range instead of the goblin's 10% or so. Maybe try shifting the CG forward (if you do, you'll probably need some more reflex to compensate). Good luck!

yeah when the plane

yeah that is what's supposed to happen.

I agree with @Jackson T, its likely tail heavy. My Versa wing is a pleasure to fly with the CG @ 30%, and is flying squirrel @31%
