12" X 12" BENNETT TRIM TABS (no obvious corrosion) $300 plus new I was told I had to increase the size of my tabs to resolve a issue, but truth be told I needed to have wait a few seconds longer or change the pitch of my prop. I left the previous set unpainted due to the possibility dissimilar metal corrosion and thet corroded away even with the zink installed. So I painted this set and had zero issues with corrosion. Most important thing is that they are in great shape. You can remove the paint easily with a scrapper, if you so choose.
