The big difference is not the engine but the people that run them. Run a 2 stroke like it should be run and it will work just fine; try and run it like a 4 stroke engine and it will bite you. The majority of people that I know that had 2 stroke engine issues, didn't know what they were doing and caused the engine problems. A 2 stroke is NOT designed to be idled like a 4 stroke engine. I've run 2 strokes for over 20 years and the only problem I ever had with one was caused by me! I've had people tell me that they don't trust a 2 stroke. I tell them not to fly behind one because they will be the one creating the problem. Cont and Lyc engines break all the time for various reasons. Most engines give us plenty of warning that something is not working correctly and IF we pay attention to what they are saying, we won't break them.. Just my .05 worth. Ron

I really couldnt bring myself to fly behind a 2 stroke which is why I bought one with the Jab. I have friends who swear by the 2 strokes, but the fact is they have more 'issues'. As to another aspect, the Jab was too nose heavy for the avid design and the fixes are difficult. That airframe was designed for a light 2 stroke out front. Over time, they got heavier all way around and nose heavy. It still flew nicely at power, but pull the power back and it was a lawn dart unless you corrected with lots of up trim and some aft stick pressure. (and the CG was well in envelope). If the plane had sufficient baggage, it was much better at lower power settings. The KR seems like its geometrically friendly to heavier engines. And (from my readings, havent built mine yet) can get tail heavy quick as Mark found out hauling those engine parts. This is actually a great problem to have from my perspective. Stuff a Corvair on the front and it's (apparently) not nose heavy! So, I just cant imagine how a 582 would work out with CG. And my Avid experience showed that in envelope doesnt always mean flies well.
