Far be it from me to argue with you guys, but yes, 16-18 #64's DO fit on the dowels (I have a Hobbistar 60). All I know is that if the wings are not tight to the fuse, add more bands...especially if you have wind gusts of 13-18 mph. Remember, I'm near Chicago...The Windy City...didn't get it's nick just from the politicians you know.
