Does anybody have any long term experience with these props? Problems, issues, maintinance, etc?
I have a few customers with them. They are well built, but, would not be my first choice. If you take it apart and re-lube yearly they can be good for a while. Be aware that they can tend to overload an engine and not allow it to attain max rated RPM. One customer went round and round with them on this and they refused to do anything to help him. He removed it because his engine was under warranty and the manufacturer insisted that his engine be able to hit max rated RPM. He went with a Max Prop that had an adjustable pitch so as not to void his warranty.
If you buy one be sure the manufacturer will stand behind their sizing. Until then just let your prop freewheel, if your gear box will allow it..
