One of the blades has a crack in it, in the same place where it appears it was welded previously (by the PO) and the tip has lost a lot of a material during the cleaning process. They are recommending a new prop and suggested switching from a 3 blade to a 4 blade. Factory spec was 20x20c
For those of you who have a 400 Express (92 era, Gas 7.4) and 4 blade props, what size/pitch are you running?
