I know most of you read the thread title and thought of a Merlin or V-1710 or R2800 or JT8D or PT6...etc
After putting some hours in the A2A accusimmed planes with their great engine simulations. I got to thinking about a great engine that kept my butt alive. I bet it kept alot of yours alive too :D
This one is a bit simpler than most of the engines simulated by A2A, but it is just a simple reliable rugged engine. I am sure a lot of you who are pilots here have ridden behind one of these, and it got you to your destination just fine. It took my abuses with ease when I was a student pilot.
The great Lycoming O-360.
