I have done proper rib stitching on a 1/3 rd Pup & a 1/4 Avro 504k . If the wing is undercambered as they both are , I put contact cement on the ribs , 2 coats , Then after the covering is on I stitched down the side of rib- under the bottom of rib up along other side of rib , tied a knot went to next position etc , On WW1 the spacing is 3/4" for 1/4 scale & 1" for 1/3rd . which is 3" space on full size . Thing is that if doing proper stitching it keeps the undercamber cloth in place for ever , wheras simulated can let goafter a few years .
i have just done some simulated stitch; personally found best way is to mark off the spaces on wing , mix up a small amount of yellow glue & talcum powder , using a toothpick jab some on the spots . leave to dry out & then put the tapes on top . Tried the small bits of fish/line to glue on , but this is a lot LOT quicker !!
