I have the Cub in the w/o ailerons and wanted to know what the CG should be.

I seem to have misplaced the plans since last time I had this little plane out.

On some of the Roadkill Series models where the C/G is especially critical, or where we expect beginning builders with limited experience in setting the C/G to be attempting this (such as with the Cub), we provide a hole in the fuselage to set the C/G.

Look on the fuselage just in front of the wing strut attachment and just above the top edge of the landing gear doubler. That little hole is for setting the C/G. Just insert a leftover piece of 1/32" wire horizontally through that hole, then hold the model upside down with that wire. The C/G is correct when the fuselage hangs level when suspended from that hole.
