Re: Modern Engines on Q2?

Exceptions don’t change the rule. Auto engnes don’t fly… I’ll go one step further…auto engines are dream killers. There’s no telling how many have wasted significant amounts of time wishing they were flying while struggling to make an auto conversion work. We have a Defiant that will never fly again because the builder was trying to use Mazda engines. He struggled so much that eventually he gave up. A lifetime of effort wasted when he could’ve been flying and enjoying his dream had he not been led down a path that somehow those Mazda engines would be superior .  When we learned of this particular Defiant we barely got there in time. The builder was so frustrated he was going to burn it. He already burned the cowlings by the time we got there. 

If your dream is to fly dont  go down that path. Auto engines are dream killers

 William Wynne can verify there are several Corvair conversions well over 1200 hours in several designs. An entire overhauled engine costs less than the 
rocker arms for a C-85/O-200.

 The engines have been flying since 1960.  Granted..low and slow back then but not so now..  Complete running valid cores average about $400. 

 Don't need to take my word for it..take a trip for yourself to Green Springs Florida and check it out.

The 2000 hr. TBO thing seems like a red hearing (non sequitur) to me.

How many experimentals get to 2000 hrs?

The key seems to be knowing when to rebuild/replace and how much cost to rebuild.
A 500 hr. TBO engine that costs $2-3k to rebuild seems like it would cover 90% of the market.
Obviously it needs to actually get to 500 hrs, 95% of the time.
