I came across this website and thought it might be some use to anyone that looking at a Geo. http://nessaaircraft.net/index.htm http://nessaaircraft.net/enginesFrame1Source1.htm "Why not the 3 cylinder. This engine has harmonic problems, it roc-n-rolls at low end. Example; you will need to install a heavy flywheel; the 4 lb flex plate from the automatic transmission will fail on you. If this lets go at 5000 rpm it will cause damage. Even after separation if nothing else you will poop your pants. You will not know what caused the entire racket, you may decide to force land and because it is going to be a bad day, now you also damaged the aircraft and if you did not get physical damage yourself, your mind will! This will lead to lock of confidence in the installation. One of my experiences, not the pooping." Seems he has some good knowledge of this engine, and it looks like he is a Transport Canada amatuerbuilt inspector of soem sort. Should be an invaluabel asset to anyone look at a GEO install http://nessaaircraft.net/builderFrame1Source1.htm Good Reading, Dave ________________________________ Message 2 _____________________________________ Time: 07:42:09 AM PST US From: "lance miller" Subject: Re: Kitfox-List: gearboxoil --- MIME Errors - No Plain-Text Section Found --- A message with no text/plain MIME section was received.

IV will accept. I have a Denney's model 3 with a 582 and I changed it for a Jabiru 2200, Dave. Like Dee and Lynn, I am very pleased with it. But both Rotax engines are also fine engines. As Bradley says, the HKS is also a fine engine, but it will give you less power than the 582. The Jabiru will give you about the same power under take-off and more power under cruise. The 912 will give you more power overall. But the engine is heavier and you will probably need to work your CG differently.

Can some body with an NSI non turbo and ground adjustable prop tell me what revs I should expect to see for best results. I was getting 4700 rpm flat out but feel I should be seeing over 5500 rpm. The prop I have put on is a 72 inch 3 blade composite which when installed into the hub comes down to 70inch.

I've been following the threads going back and forth between yourself and others with your own plane and being at the same point myself with engine info requirements Im really close to flying. The problem I have is that I was sent an NSI data sheet on engine performance and in it the advice was that take off engine revs should be around 6200. I shook my head in disbelieve at these figures and asked a mate who overhauled my engine what he thought and he agreed that the figures were high. I was wondering if the figures quoted are for the NSI engine with the CAP system. I dont know if that would make any difference or not but 6200 seem very high and more a kin to the 2 stroke rev range than a four stroke. Figures quoted in the NSI EA 81 OPERATING LIMITS are as follows. Idle RPM 1350-1400 Cruise RPM 3200-4500 Take off RPM 6200 Max Continuous RPM 5800 Never exceed RPM 6500 Regards Graeme ----- Original Message ----- From: John Anderson To: kitfox-list@matronics.com Sent: Monday, July 24, 2006 2:09 PM Subject: RE: Kitfox-List: Setting prop to revs --> Kitfox-List message posted by: "John Anderson" Fo a start Graeme, if you get 5000 static, that will certinly get you flying safely. At 4700 your'e very near top of the tq curve.
