Thanks for the reply. My head was set up as described in the thread. The swash was set at a half inch etc., but I have had a few blade strikes. The current mainshaft and gear are brand new adn jsut installed, so it really shouldn't be the mainshaft that's the problem. I wonder if my jesus pin is deformed from blade strikes etc.

I'm thinking seriously about getting the full cnc head. Looking at how much flex the plastic has I'm thinking aluminum may be the way to go. I figure the cost of the aluminum swash, the bell hiller upgrade, and replacing other parts that are fitting a little too loose IMO is going to make it so that just going aluminum may be worth it in the long run. I'm still pretty new and still climbing the learning curve, but it seems to me that the lack of slop tha the aluminum head is reported to have would probably help with learning a bit.

I've seen a few posts about the aluminum head, but not a lot of followup. For those that have it... has it made a big difference? Would it make learning a little easier? I like the idea of more durable parts, and looking at the cost of the replacement parts for it? Well they really aren't that expensive.
