actually do not worry too much about the wing laoading at 14 pounds a stafford b-24 is pushing close to 35 oz/sq ft and flies fine.if you build light you should be able to come in well under 20 pounds.chris golds 90 lancaster is built from foam and covered with kradt paper and glue,very heavy vs cloth and epoxy.they use .25 size engines and fly fine.give me your e-mail address and i will send picturers of the flap and rudder linkage as well as scketch from the plans.when i calculated wing area of my 100" connie I was around 1000 squares.you must remember that wing area increases exponentially as you increase the scaling factor.ie a model 2x bigger has 4 x the area.there have been successful flights of the controline model converted to r/c with four os 25[old stlye] in rcm about 1975.no retracts at that size though.one thing is do not get discouraged.If you need help e-mail me or ask here.
