Reading those old Contact! articles made me wonder what the rotary roster looks like now.

With the steep increase in = Lycoming engines and their long (2 - 4 years) lead time, I'm wondering why/if they're an increased interest in DIY rotary engine installs. With 200 RWS PSRUs out there (even if most of them may be 2.17:1) that's still a good supply of reasonably priced PSRUs.

Is it that there are = relatively few real experimenters out there or that we're not really promoting the rotary? I know our most repeated statement is: "If you just want to go fly bolt on a Lycoming, if you want to tinker do an autoconversion". But with prices and lead times, does that still hold true?
