Hey guys, it's just a thought, but I saw a Harry Higley's prop lock (it's just a pretty nut) on tower's site and figured you could use one of those and something like a dubro aluminum prop nut. I think it would look a lot better than just a couple of nuts on the shaft and a lot cheaper than a spinner too. Is there any down side to this? My UCANDO should be in later this week and I was thinking about this setup for my YS91.
