Rotax 582 conversion install on Challenger 2 ultralight

I upgraded my challenger 2 from a Rotax 503 air cooled engine to the higher HP liquid cooled Rotax 582. I go over all the details in this video of the install including small tips and torque specs. This is just my experience so please always do your own homework if doing something similar:) I've had a lot of help from John Baker (rotacrepair.ca) Bill Bryan(Toronto aerosport , stouffville airport) Greg Klemp(sheer technologies), and Mike Harrison(quad city challenger). Thank you to all you guys!

I would be very curious in a true weight comparison between a 503 install and the 582 install. all said and done i'm sure there is not much power to weight ratio gain for the cost of the 582.

It has WAY more performance than 503. No comparison.
Yes the 503 is good and gets the job done.

very nice

That engine sucks. So fkng costly and the sound?? It’s outstanding. When fly low people calling the cops on you. … sucks. No way il get a total 2 cycles. It’s a grass trimmer

[@aerialambitions3066]

I don’t have any other options. Even if I get 4 rebuilds out of the engine it’s still cheaper then a rotax 4 stroke which I can’t use anyway because they are to heavy. I can only use approved engines by the manufacturer to keep it an advanced ultralight as well. Been working great for me:) love it!
