Default seagull 120 spacewalker cg point at fuselage

I have a seagull 120 spacewalker with DLE 30. I want to find the cg of wing at fuselage instead of the 11cm at wing tip.
Has anyone flown one with a 30 and what was your cg point

I don't have this plane but I believe the main spare is straight on this wing. If so it is 11cm back at any point along the wing. I would also balance it inverted.

28 to 32 percent of the chord measured from the leading edge of the wing. Engine size is irrelevant.

My apologies if this comes off a bit short but people really need to learn to calculate their CG and more importantly how to make CG changes as required. CG affects so many things like landing speed and trim changes at differing speeds. To a smaller extent control cross coupling.

Put it on the wing tube or the main spar and you'll be close. If you want to stay conservative for a maiden, put it on the front edge.

If nothing else, use the wing tube/main spar to verify your calculations.
