Any rotary powered BD-5s under construction or flying?

Jim Rudholm


The [Mazda] Rotary is too big for a BD-5. Rather it's too heavy. The BD-5 is
designed around a 3 cyl 2-stroke engine. The design weight was about 150
pounds. Less than 50 hp. Several have been built using the Rotax 2
cycles. If a proper single rotor is produced, it could work.
