For what it's worth - I'm flying behind a Subaru on my Jodel and truly love it. To the point where I am swapping the engine on my RV3 to a Subaru as well.
It has taken me three tries with three different engines, gearboxes, propellers and ECUs, at least 1500 hours of modifications, several years of spending online researching, talking to hundreds of people, filtering out the golden nuggets from the opinions, several steaming landings and enough money to buy myself two brand new O-320s to get to where I am now.
If you just want to fly, don't go here. Just don't. Really.
Me, I am too stubborn to quit anything, and so I persevered. And I would do it again (AM doing it again, actually), but that's just me. If you are up for one heck of a learning curve and want to see this through, then by all means forge ahead. This path is paved with failed projects though.
