KR> Jabiru 3300 weight vs corvair
Well written Pete and I see your point and theirs too. We are all subject to some type of authority and a well written proposal will go a long way to getting things done over there.

KR> Jabiru 3300 weight vs corvair
In defence of the UK LAA, they have a legal responsibility for all aircraft granted UK permits to fly. The LAA represents the interests of UK fliers in many ways including fighting an endless battle over loss of airspace, EU rules harmonization. Whilst not perfect, the LAA largely run by unpaid volunteers does a great job. If an aircraft crashes in UK, it always crashes close to somewhere, so attracts a lot of media attention - leading to all sorts of negative publicity for the LAA, this undermines all the good work. The LAA engineering dept consists of 4 blokes who look after all aspects of design build and maintenance of 2000+ planes so time spent looking at one design proposal affecting a single project has to be balanced again the time needed by all the other work. For example an A/D for an RV6 could affect a hundred or so planes. So you can see its not so simple for the LAA to spend several days evaluating a single use mod. The LAA engineering dept is funded by member subscriptions and permit fees, so the cost of their work has to be born by all members of the Association, so I hope you see why the engineer says NO unless he gets a well researched and documented proposal.

KR> Jabiru 3300 weight vs corvair
Mark I have sent an email to Bill Marcy at the email address he used in the archives. I hope he still uses that email. Regarding the engine weight issue. We have incorporated extra longerons top and bottom on the forward part of the fuselage to deal with the extra load. However its no good without numbers, so I hope Bill can come up with some. Many thanks for your help. Peter Drake www.peterskr2s.co.uk - Original Message - From: "Mark Langford" To: "KRnet" Sent: Sunday, August 28, 2011 10:54 PM Subject: Re: KR> Jabiru 3300 weight vs corvair There's a guy named Bill Marcy (who I think is from Arizona or Colorado or somewhere out that way) that did some structural analysis for Rand Robinson in the 90's, and one of the things he said at the first OSH forum I went to was that his analysis showed that O-200s and "just about anything else that would fit" would be OK for the airframe of the KR2S, thanks to the beefing up it got at the firewall (as opposed to the KR2). Take a look at the archives (http://www.maddyhome.com/krsrch/index.jsp) and search for "Marcy" and you may turn up his address. RR should have his analysis that reports this info though. I assume she paid him to do the work, so she should have it somewhere. There's a message from Austrian Christian Kogelmann where he says he has the flight envelope analysis from Marcy that details max gross weight, so he may know how to get in touch with him. I'm betting RR knows how to get in touch with him as well. I can tell you that my Corvair engine weighs right at 245 pounds complete, with everything it needs to run except fuel in the lines and electrons in the wires (that's carb, exhaust, airbox, generator, oil, etc), and on my first flight I tested the mount to 5 g's on the meter. I doubt the published weight for Continentals or Jabirus is absolutely "full-up", so keep that in mind when my 245 sounds heavy. It's the downward force of a hard landing that might separate the engine and firewall from the fuselage, not just pulling it through the air. That's why it's more a weight issue than a power issue. Just improving the load path from the mount to the outer edges of the firewall (near the longerons) goes a long way to strengthening that setup. As for Corvair hp, mine was rated at 110 hp at 4400 rpm, but that was with a different cam and I've got 15% more displacement now. You can sift through the stuff at http://www.n56ml.com/corvair/specs.html and find just about anything you want to know about the stock Corvair specs or the implementation that I'm running, with all kinds of other details at http://www.n56ml.com/corvair ...

KR> gross weight
Is the gross weight the same for the KR2s as for the KR2? The KR2 plans show 900 lbs. I suspect it would be more for the KR2s, but haven't found it. I did use the search engine and find the answer to how to do fuel flow on an engine driven fuel pump and some information on the climb angle. Very useful tool. Dan
