Hi, Chris, ASSUMING we're talking balsa USA 1/4 scale DR1...
directly from Dave Lewis CG on the Balsa USA 1/4 scale Fokker Triplane:
The CG should be 3-5/8” back from the leading edge of the top wing. Start with it at 3-5/8” I don’t care how much weight you have to add to get it there, just get it there.
Then after you’ve flown it and gotten comfortable with it you might want to move it back a little (not to 5”) but a little.
