Yes and it is so simple:

measure the distance (for this particular airplane) from the leading edge to the trailing edge, next divide that distance you just measured by four. That 'figure' will be the quarter chord, 25%mac. All that is now left to do is just measure back from the leading edge that figure or distance and that is your target point the cg. Yes if you like for ease of checking the cg just project this figure inward next to the fuselage.

The last step is to do whatever you gotta do to make the airplane balance 'level' at that target point, not a little nose down for Mother and Country. if you do the nose down a little thing then that means you have not balanced at the target point but some unknown point forward.

Now notice I have completely ignored your info on what the instructions say or said, I don,t care. I have run into so many no name wanna be so called instructions some even just 'pictografts. And many dangerously wrong and yes only just my opinion that I feel this is problem for many people.

If you want the best chance to make your ship a nice flyer then truly balance at the 25%mac or quarter chord and I know (yes my opinion agine) that you will be rewarded with the best ship possible.
