Chris, I've had pretty good success with mine. It was a mid 80's Revmaster that I bought used and have put approx 700 hours on since I started flying her in 2006. I did replace the heads at about 350 hours. The heads were original and I did not know how many hours were put on them. The engine is pretty reliable and easy to work on in my opinion. I did replace the case due to a crack at one point and have converted it to automotive plugs. There are some details on my web site.
