On a recent trip a group of us ended up flying for around 3 hours in rain that was at times very heavy.An ivo with stainless tape needed the tape removed as it went lumpy and had splits in it,my ivo with clear tape is ok but appears to be lifting on the outer leading edge,the rest is perfect.A GSC without tape didn't get any damage,and a local prop without tape but an epoxy leading edge looks and feels like sandpaper on its edge. The GSC was a surprise!
What thickness tape is the best?i see spruce lists two thicknesses,would the difference in thickness be noticeable in prop efficiency
