That is the safe point I gave, but I would start at 230mm back from the wing/fuse join line.
The UF copes with a big range, we have flown it between 220 and 240mm (3/4" range) and it has control power and balance to cope with both extremes. A lot of guys end up 230-235mm gear down and a little fuel in fuse tank....but always with balance its down to what you feel comfortable with.
