Alternative Engines

Post by AlabamaSlingPilot »

Has anyone looked at or evaluated the use of an alternative Powerplant? There are UL Power, D-Motor, Viking and Aeromentum, and they all have engines in the range of 140 hp and the approximate weight of the Rotax 915. There may be others, I am just not aware. I know that Sling could not support this, but it does open up some interesting possibilities to someone who might like to push the boundaries. These, after all are experimental and can be modified any way the builder wants. Just wondering if anyone has considered......

I noodle this around on occasion. The one that has my eye is the Higgs https://www.ac-aero.com/falcon-fl200/

In talking with these guys at the show, they have engines already running in cars, but their long game has always been aircraft. It's absolutely impressive what they are doing. That's the long game. I'm staying true to the Rotax 915 for my Tsi build as I need to learn more about how the whole thing works together before I start tinkering with an engine that wasn't necessarily designed for the Tsi platform. But to change out a 135/141hp engine for a 210hp engine that runs JetA? It has my attention.

In speaking with one of the vendors at Oshkosh this past week. He is working on his RV-10 with the next model up https://www.ac-aero.com/hawkrv10/ The RV-10 running that engine will definitely smoke most things out there with the additional horsepower and less weight.

I think every plane has their strengths and weaknesses. In the case of the Tsi, the Rotax 915 is one of its greatest strengths. Sips fuel, runs on mogas or 100LL, turbocharged, fadec, etc. YMMV :D
