I would easily buy that a KR-2 will maintain altitude at 18HP. Mine could maintain altitude at under 1/4 throttle. Hey Mark, next time you are up see what manifold pressure you can maintain altitude at. That will tell us.

Problems: - Weight - Single ignition - Carburation\Fuels systems is not designed for aviation - Cost - BMW stuff is expensive (in Australia anyway) and spare parts are even more expensive :-) - Redrive weight and cost and re-engineering Plusses: - I don't see any That's my opinion, for what it's worth - maybe 2 cents Regards Barry Kruyssen Cairns, Australia k...@bigpond.com http://www.users.bigpond.com/kr2/kr2.htm -Original Message- From: krnet-boun...@mylist.net [mailto:krnet-boun...@mylist.net] On Behalf Of James Wester Sent: Monday, 15 May 2006 7:54 AM To: kr...@mailinglists.org Cc: KRnet Subject: KR> BMW BOXER ( candidate ? ) Hey folks .James here .
