My project has not flown yet but from talking to Marty Roberts the prop ought to be pretty close on diameter and pitch. If your KR has the standard 24 inch Diehl gear a 62 inch prop won't give you much ground clearance in the tail up attitude. I think the FAA would like to see something in the neighborhood of nine inches or so. Anything less with a hard landing and the gear flex could have you cutting the grass in the runway cracks with the prop !!

Any airworthiness changes to an existing airframe require recertification of affected flight parameters. If that change affects existing aircraft, an AD will be issued. Since when did Aviation Safety become the authoritative voice of aviation. It's one author opinion and the word apparently is a little bit suspicious (gotta cool off some here:-) Mike, it's very simple, I really don't want to get into a discussion of certified aircraft on the KRNet but a certified aircraft MUST meet minimum flight requirements to become/or remain certified. Stalls are a part of that flight regimen........no more, no less. A spin is nothing more than an uncoordinated stall. I'll discuss flying but not Tomahawks on the KRNet.

I built a bottomless alum box to cover both held on with 1/4 inch metal screws into the firewall. The open bottom will let me drain the gasolator on preflight. Will cool the box with a scat tube from the back of the cooling tin at the top, rear of the engine. Dana's right. A good share of homebuilt accidents are the result of fuel flow problems. A little extra effort could save a lot of grief. Bob PS Used white scrap alum guttering given me by the local gutter installer. They usually have lots of it so material cost was 0. This is a non-structural item. ---------------------------------------------------------------------- Subject: Re: engine block heater From: "Richard Parker" Date: Fri, 28 Jan 2000 07:06:46 PST X-Message-Number: 8 You can buy heater pads with high temperature adhesive on them.

With no mag back there, you don't need to dish the firewall or anything else like that. He has some excellent information available on what to do and how to measure for building a mount for the Corvair in a KR, and is working with quite a good number of KR folks on refining this. He is also very good about letting you know that it won't be the end of the world if the CG doesn't hit just right the first time you do W&B; it can be adjusted fairly easily and without throwing an old battery in the tail, either. You won't want to hang it way out there off the nose though; it will weigh at least 220, depending on what starter, alternator, carb, exhaust, etc. you hang on it.

Well it's time for me to move forward with a KR2s project. I have been gathering building supplies and misc. parts and I want to begine building the real thing. 1.Do I need to Join the EAA? 2.Do I need to file anything before I start building? 3.Can I rebuild a pre-owned HAPI conversion that I have ? 4.

My family will be building a home at a flying located at a state airport and it looks like the hanger will have to wait to be built. The question I have is that we will look at, maybe, is at least have the foundation, floor, and approach from the taxi way built. How wide should I have the builder of the home make the approach? I figure, eventually, I would have an airplane no bigger than a Cessna 182. What is the measurements of the main landing gear of a C-182 and how much wider would someone make the approach than such aircraft? We are trying to save a little cost on this so I can have a hanger in the future i.e. not shock the wife. I plan to have packed gravel along the sides too. John F.

I use no fuel pump and no in-line filter, but I do use a gascolator. I wonder if any of these guys ever had a car that quit or ran rough due to a in-line filter that started to block fuel flow after filtering dirty fuel. Bad problem at 5000'. With a gascolator they would have been able the wash out that dirt just before each flight.
