difficult land precisely also suffer bit dead air sink ing speed Most F3B-type Gliders seem fall general category too although now getting wing loadings down some big British polyhedral floaters probably would also suffer landing precision high priorityjust old Sailaires times ships would great dead air would have pretty good range Real large ships could have launching disadvantage moderately powered winches Naturally opinion landing precision important contest included good mix weather conditions plane like Windsong would have edge large enough sec far off being light enough get good tow about winch can range out best get home near-impossible situations can get top times dead air still land great precision As know however cant tell what plane will win particular contest can guess odds have seen big contests won plane looked like piece xxxx opinion no single contest conclusive best pilot nor what best plane overall contest adds little bit information big picture big scorecard sky
