Got my first flight in 2 days ago and my second flight this morning. I kept both flights around 30 minutes as per the recommended break in procedure. So far it seems to run great. Peak RPM seemed to be around 8600 but the plug was pretty black/wet so I'm sure I can lean it out a bit. I'm going to leave it rich for the break in at least. Temp was about 405 during my climb out and then settled around 355 while putting around.

From what I can tell the 2019 just has a few updates to the 2018 version. 1. Coated cylinder head to reduce temps slightly along with removing the original cylinder head shroud. 2. Modification of original ignition (removal of 1 of the feet) 3. Guide for pull start cord. All of these mods are able to be performed on the older engines so they should be pretty comparable.

Thanks for all this info. My frame arrived this week, I needed spacers made to give clearance between the cylinder head and frame but I should have it together within a week. Going to do the break in and then hopefully I'll get a first flight soon after. I'll post up my experiences once I get it going.

Is there a benefit to them? It seemed like you didn't notice a degradation in performance with yours out.

I saw the update to the service interval. It's not always easy to tell if metal is fatiguing though. If they're not really needed I might just remove them as a precaution.

Just got in a new 2018 EOS 150. Currently working through some of the service bulletins to ensure it's good to go before I get it mounted and begin breaking it in. One of the service bulletins has you check the piston ring gap (for motors under serial # 122 which mine of course is). I have done this and filed them to the appropriate spec since mine were below their spec. I'm wondering if reusing the gaskets is going to be an issue on a never started engine? Also wondering if I should just remove the stainless reed backers before I even start using the motor?
