    That $60K is for the whole installation, including a prop and instrumentation. The engine on its own is $30k cheaper than the list price of a new IO-550. ($10k less than street price) Also, nobody in their right mind would try to install an IO-550 on a Kitfox.

    Obviously your missing the point here. I was making a comparison between what the cost of a Rotax is vs a more established, more powerful and more accepted engine.

    I never implied someone would stuff an IO-550 into a kitfox. It was what we refer to as an analogy to draw a comparison towards value.

    I didn't miss your point, and wasn't trying to get personal. Just pointing out the flaw in the comparison. $60K is for a complete factory new firewall forward on the 915.

    Rotax is an established engine option. Also, the Rotax engine was engineered in the early 80's using modern metallurgy compared to Lycoming/Continentals. It has a proven history, good to excellent power output at a lower weight. Which results in an added benefit of not carrying extra weight which reduces performance. Fuel efficiency means not having to carry extra fuel which is extra weight.

    Well it looks like your Rotax was reinstalled into another Predator. I love that Plane.

    You can put anything in the STi. Trent used to have a 912UL in his. He did bump up the power to 105 at some point.

    The STI was designed for 100mph 100’ landing and take off, on 100hp


    Thanks Eddie! I love the way she looks AND performs

    Steve, since the STi version utilizes a 7SS fuselage I’m thinking just about every engine they offer on the standard kit might be able to be used on the STi. What I know is the factory has flown the STi with first a 912uls, then a Titan 180 hp. engine and now the 915. The 912 iS fuel injected and 914 should work well too.
    Maybe a Rotec radial. I really haven’t asked them so I may be way off.
