Revmaster Aviation is experimenting with a new R3000 100hp engine and hope to have it ready for full production in 2006 @ $10000. By the time some of you/us are finished your KR building (and sanding) you might be ready to go this route. The engine is in testing (running) stage now with mostly all newly designed parts and the old VW bugaboos taken care of. This pricing seems to me to fit in between a good Corvair and Jab with the 0-200 (new) far away. Something to ponder (Contact magazine #80 by John Moyle)
