When I riveted the autopilot servo bracket in the fuselage, I wasn't satisfied with the rivets, so I decided to buy some Cherry Max rivets and give them a try. After drilling the old 1/8" rivets out, I enlarged the holes for the 5/32" Cherry Max rivets and set them. I have to admit that I wish I had used these on a couple of troublesome rivets a couple of times in the past...they are very easy to use, and aside from costing about 20x more than solid rivets, they sure were perfect for what I needed!
