I hope AvWeb continues to feature new applications of drone/electric powerplant tech. This is just one outstanding example of how new engineering can contribute to modern aviation. As my O-360 creeps up on TBO, I’m very interested in finding a replacement powerplant that leverages 21st century innovations in ICE, but I remain hopeful that my RV-7 could someday be powered electrically or at least by hybrid means. Fingers crossed.
