Fox .36 Mark VI

Fred, these engines are just difficult to find parts for. Even finding good glass props can be difficult. Fox has virtually no parts for them. Each of the MK series progressively were better than the version prior. Unfortunately, they all had flaws. Cost was typically the determining factor as to why things were left and not repaired or redesigned. The MK VI however was in my opinion well on it's way to being the best of the MK series engines. Fox does have head buttons, but when I received it, I found it to be for the .40 but it was the double bubble head. I had my friend Dan turn the button down until it fit the .36 liner. Dan also made me some head shims or various thickness. Bottom line is that Ebay is pretty much your parts supply. While some of the combat fliers are getting older and selling off these items, they pretty much stay within the combat group. Every now and again a MK IV pops up with MK VI internals. My friend AL has had Nelson internal installed into some of his MK series cases. This however comes with quite a price tag. Between the piston rod and liner and machine work, the cost is more than the Nelson was new. Ken
