Bottom Rear Fuselage Sheeting
As mentioned earlier, there are balsa doublers for F20 so that existing lengths of balsa can be used to sheet the rear bottom of the fuselage. If you want to use most of the length of a 48" sheet, as I did, you can take the sheeting back to F26 and make up your own doubler.
The rudder pull-pull cables will be taken care of later through the stab opening and the remaining unsheeted bottom tail area.
I haven't mentioned this before, but the balsa WILL shrink when dry, and may change shape. Final fitting is done when dry.
Also, before continuing, it is recommended that the wiring for a stab-mounted servo (if used) be put in now. It is harder later (yea, first-hand knowledge).

Bottom side sheets go to F26 (using trimmed 48" lengths), where 1/4" infill is added for gluing rearmost sheeting.
Wet sheeting being formed using packing tape and pins. Masking tape would have expanded when wet. Left overnight, the balsa surface under the tape was still damp. Tape removed for final drying, pinning as needed. Both sides wet formed before gluing either
Rear bottom sheeting trimmed at keel. 2" Scotch masking tape seemed to work well for gluing. Put glue on formers, keel, and longeron; transferred to fuselage side and taped tight. A few pins were all that were needed.
Side view of glued rear sheeting. 2" tape was used to hold sheeting tight at longeron joint and also acted as a hinge to transfer glue from fuselage parts to sheeting. Scotch green masking tape could be used now because all was dry.
Bottom right sheet (left in photo) being glued. Tape hinge at longeron keeps everything in position while doing the final fitting.
