Gary, Most of the tapes you see on full scale airplanes is 2" so at 1/4 the 1/2" tape is jus right. Hurri is right about the hair setting tape and the pinked edges are about right. For straight edged tapes use paper surgical tape. The tapes around the trailing edges and leading edges was 3-4" tape so keep that in mind. Also when doing the tapes the rib tapes go on first then the trailing edge tapes over the rib tapes. Also there are tapes werever there is an edge of wood or metal or tubing under the fabric. Don
