Motor is Zenoah G26 modified to electronic ign. No mount needed. 16 oz tank(overkill) 500ma ign batt, up front lower right.
1400ma rec pack at wing tube. Throttle servo in front of pull-pull rudder. Those two could be moved forward for a very small gain in forward CG. Hate to move the receiver stuff any closer to the ignition system.

I think CA literally scaled this 24% down from their 27% A good example of reverse engineering gone haywire

SCOU, if you haven't mounted your wing tube in the fuse, it may be worth relocating rearward. Looks like there's enough wood there to do the job. I tend to like a tailheavy setup, so with some luck, my 1/2" back CG may be ok. Time will tell...
