I really woudn't try flying this till you get the CG forward. Models like this fly best with the CG truly at the leading edge and I have seen at least a couple show the CG in front of the LE.

Having a model plane with the CG even slightly too far rearward will result in gross control problems wheras even if it is far too forward, just mushes the control a great deal but you still have positive control you can trust.

Electric3D, your model looks well assembled and painted. A joy to look at.
However I can see two mitakes that in the future you might try to avoid. Both of which have played a part of your CG so far back from where it needs to be. I think you went too heavy with the paint as well.

You can help by sanding all portions behind the CG. A lot. Much sanding. Agressive sanding. Then repainting with just a light coat of paint.

The left front wheel needs some care as this will not track in your favor.
Another potential problem is the elevator hinge. It must move freely. By this I mean that the weight of the elevator alone would be enough to cause the elevator to droop all the way down when at rest. If not you will have little or no control in flight. Without the linkage hooked to it you should be able to blow gently on the elevator and have it move all the way up or down.

I am so glad you have chisen to share this wonderful project here and am glad also you have run the engine before taking it to the flying field!
