Default CG on a spitfire?

I have a Pico Spitfire 1/7 scale with a 4 degree dihildal (or however u spell it) but I do not know where the CG is. Can anyone else help me out. Maybe even if you own a spitfire can give me an idea where it is. I do not know if it changes as the dihilidal changes or not. But any pointers will be apprecated.

Default spitfire CG starting value

what I usually do in cases like this, is the following:
1. measure your wingspan an divide it by 2 -> length l
2. from the wing centre go to 0.4*l
3. take 28% of t (profile length at 0.4*l)
4. your CG will be at this point.

This works as long as the wing has a nearly elliptical shape (->spitfire). This CG is a good starting point. If the wing shape shouldn't be exactly spitfire like, the plane will be slightly nose-heavy. I never encountered any tail-heavy configuration with this method.
Have a look at the drawing too (not the best one I made..:-) )

Hope this helps you
