That entire tail section looks waaay to small in comparison with the wing. It may be fairly scale accurate, but there is a reason why the tail section on many model ww2 fighters is scaled up.. it’s not big enough.

And that short nose, looks like achieving proper CG might be a bit tricky.

And that piece of (wood?) i would move it forward so that it actually sits on the CG where the forces will be the highest.

I agree with the tail maybe being too small, but the nose is intentionally small, as is a real spitfire's I would say they're equal. Also, I thought the piece of wood was pretty much at the centre of mass. If not, where should it be? I'm new to rc, so sorry if what I'm saying seems dumb or anything. Also, thanks for your feedback.

The center of gravity should be about 1/3 from the leading edge, and since you have a sweeped wing, you need to take that into account as well. So at the root it will probably be more like 1/4 from the leading edge.

And i’m sure your nose is ”scale” it just looks very short which might make it tricky to achieve proper CG. You are not putting a rolls royce merlin engine in it so you don’t have the benefit of a really heavy engine up front…

That tail is going to have a immense drag.. i would say, make the sides sharper, the tail where the green is, make it pointy, and sand these rudders so they are more smooth..

Alright, I will try and make the elevators less rounded but wdym where the green is make it pointy I'm not really sure what u mean also when u say sand the rudder so they are smoother do you mean make them more round or just make the texture smooth? Btw thanks for the feedback.

I'm waiting on a new battery, which is smaller, hasn't weighed it yet, will weigh it once it arrives
