Build-it-yourself aircraft

Found this interesting tidbit. First Open Source airplane could cost just $15,000.

I think the conditional wording is the critical thing.  It could cost 15,000, but I don't think it will.  I'm not sure what engine they think costs less than $15,000, but I'm not sure I'd fly in it.

Light Sport Aircraft do not use regular aircraft engines. They use a modified automotive engine, Rotax engine are popular and cost under $3K.
