I have the same Charlesworth design Lo100 and the incidences are as per plan, with the CG at 120mm behind the LE at the root (not from the cut out where the cockpit is).
Flies a treat, but full crow means it stops with 80* down flap - only needs about half crow to be sensible on the landings.

Re: LO 100

I have the LO100 built to the Cliff Charlesworth plan which I built a couple of years ago, I use a centre of gravity calculator on line and its given me the following readings, with a low static margin of 5% ( greater elevator authority) its giving a c.g. of 113mm
" " medium " " 10% " " " " 100mm
" " high " " 15% ( greater stability less authority ) " " " 89mm
Hope this helps, but I have tried these and use 89mm, any greater and its a real handful, which of course you may like, my models tend to be a bit heavy.
As an exercise I also built the wing in one piece which makes it a bit easier to rig.
Following on from this I have also built wings for the LO150 version and use the same fuselage.
Get in touch, you aren't to far away.
