In today’s aviation experimental world, you can build your own airplane by buying a kit and choosing whichever engine you like to fly. Buying an engine for your airplane is one of the most expensive cost to your build, if not the most expensive. This is why some builders choose to buy an engine first before they purchase the kit of airplane to build.
Generally a certified aircraft engine will cost on average $15,000 – $30,000. And this is just for the 150HP engines and below. If you want power output in the 180 HP plus region, then you’re going to shell our more dollars. This is where auto conversion engines comes in.
Auto conversion engines are basically car engines that are retooled and used for flying. Or as Jan from Viking aircraft will tell you; we try to do as little as we can to our Honda engines to change it. So why use a car engine to fly airplanes? well for one, it’s less expensive to buy and to maintain. This is because car engines like Honda are already mass produced and parts/labor are available everywhere.
Some are still very skeptical about using car engines for flying. Jan covers some of those concerns in this video.
