Hi all,
I'm currently looking into building my first homebuilt aircraft, and because I chose the most expensive hobby, I want to have some assurance about my future project. For background, I am looking to build a tandem seat aircraft primarily for aerobatic purposes.
With that in mind, I am under the belief that AVGAS (100LL) will disappear by the time my little RV will be complete (2030-2035). So, I'm looking at engines that would be able to run off the next best thing, whether that's MOGAS, 91UL, Jet-A1 or some sustainable aviation fuel (SAF).
I understand that Rotax is the best choice for versatility, however it’s not common to see Rotax outside of the RV-12 and that one RV-4. I heard Lycoming can take some high-octane UL fuel (100UL), can it do lower? Does anyone have any suggestions for engines that won’t be affected by the phasing out of 100LL (and potentially other fuels).
