Not the same type of hardware. They might need larger engines for their reusable drones, but the ones they used for Shaheds are in-house clones (funnily enough, a Wankel engine for one of them). The Wikipedia pages for the suicide Shaheds has teardowns and sources.

huh cool. I guess the Wankel's found a niche that doesn't mind the short engine rebuild period.
