So who is selling these engines now??
I bought mine last year in June i think ( jc60 ) From planeaddicts.com it is my understanding that they stopped selling all the jc engines.

I was absolutely in love with it for about 4 gallons of use and then it started to leak at the base gasket. So in looking at the cylinder I learned that the lining that JC uses in there cylinders is crap. Mind you your cylinder fins are different from what i have.. So I really hope they have addressed the lining issue. I love the design of the engines primarily because it has HUGE ports it was designed to pump a lot of air which translates to HP. Also I love the finish in the case but they had to top it off with a grossly thin lining that wont handle the abuse of ANY excess carbon so here Is my suggestion.. I looked at the pistons out of a da200 that has over 20 gallons of use and They were in pristine Condition from the perfect airplane engine loving oil that redline makes.. Here is a clip that shows proof of it.

Here is a pic taken through the exhaust port at the New Warrantied cylinder in my engine.



If i were you I'd put the redline in the mix now and just deal with the 15 gallon break in period.
Just my 2 cents of real world experience though.. Love the sbach by the way

Here is my bird..
