The original plan shows solid bulkheads, which you would use with a single channel radio.  I expect that modern builders will appreciate the mods I’ve included in my kit, including bulkheads with big holes in the middle for push rods, batteries, fuel tank, etc.  If you want to add an elevator to your Esquire, just make one from 1/8″ or 3/16″ balsa, about an inch wide, and add it to the stabilizer.

When ordering, please specify if you want the original version, or the aileron modification, which includes dihedral braces with less dihedral, as well as trimmed ribs.  When building the aileron version, use a 3/16″ balsa stick at the trailing edge of the ribs.
