Van’s RV-15 at Oshkosh – Ten

Probably to avoid having to answer the question a thousand times a day, someone at Van's used a Sharpie to write the engine model right on the aluminum just rear of the firewall. The answer is, it's a Lycoming 390-EXP-119, the same 215-hp engine that Van's has been offering on its RV-14 since 2020.
