    Hey Chris looks nice and will be interesting to see the cruise speed difference between the pictured tires and the "big boots" still to come. An external caliper cleveland bottom end with dual piston caliper is about as good a performance condition as you can put on a plane like this. Looking like in some of the pictures the matco masters are the super short mc-4g? One thing with the avid rudder bar configuration I'd be watching for is that with brake activation master cylinder travel is that they can't travel backwards,towards the rudder pedal when you step on the brakes. With rudder bar flexing there is then potential to get an over center lockup condition. I went with the mc-4d. Longer,always moving away when stepping on the brakes.

    So in your opinion what rpm is is too low to run these engines?

    I think a lot of builder have gotten the planes sorted out to their liking in some cases don't want to believe 90% of what is being floated on the forums. I did build some f-7a's f37-a's for my plane. maybe at some point I will post up my thoughts about building them and how they work. Building them is one thing....building them to be consistently identical was the challenge. The original f-7's my plane had weren't.

    Hey Chris I had been buying springs from any number of local leaf spring vendors and they just didn't last either too hard and would break or soft and needing constant re arching till they finally broke or I gave up on them. Went back to the single leaf aircraft spruce home builders spring modified/ shortened to suite my avid how I wanted and it is holding up way better then any of the previous springs I was working with. It was way more money but it is proving to be superior in durability.

    You could cut and modify 2 leaves into a dual spring setup possibly. I typically have 57 pounds on the tail with the plane in the weight/ balance orientation with the single leaf. These springs have really gone up...

    I would have to say I don't think there is a "set /correct" angle for the tail wheel pivot bolt to be at. Everybody has their own ideas where it should be. I personally decided to set my caster on my tail wheel to be close or near to the angle of the rudder hinges for ease of steering. With the shorter factory landing gear think the caster ended up around 5 degrees positive. The angle of the bend in the spring around 33 to 36 degrees. Went with the ACS homebuilders spring and shortened it and re drilled the holes to better fit what I thought would work best for the plane. May even have changed the arc angle a tad in a press. It is actually standing up better then any spring I had custom made from a spring shop, even though the latest acs iteration is a bit thinner then the original which is what I believe I am seeing in your facebook post.

  6. saskavid added a post in a topic 582 stutters on bumpy airstrip   

    So I looked at the link Jim posted about the bing distributor web sight. The carb slides they show are very different from the original items so I am wondering if anyone has a set of these custom fabricated ones and how they work and assemble to the existing carb hardware? They look like fully machined pieces from solid aluminum stock to my eye. 
    I was just looking and is this slide even compatible with the carbs our planes are running?it lists the slide as being for 54-1 carbs and I have no idea what model of 54 the 582 has....

    So what markings are on the heads of those socket head bolts? From what I've read online they are supposed to be made to a better tensile standard then grade 8.
    They are supposed to be on par with ISO metric standard of 12.9 or better which makes them a cut above grade 8.

    Well if your kit is mostly complete, if you have .083 spars then you should have lift struts that are 7/8 inch in diameter, and this is what is on my heavy hauler plane. The heavy hauler wing and aerobatic speed had more ribs in them then the "lighter" models.

    As Jim had said start looking over the fuel and electrical. That it sputters with dual ignition on rough ground would imply its not ignition.... but you obviously had the plugs out and the caps off if it has been sitting that long.

    Next thing to check is the thickness of the aluminum wing spars. This will point you in the direction of what your gross weight will be with the stol rib configuration.

    The "kit" that went on to become the plane I now have was invoiced and delivered in late january to mid febuary of 1991 with a serial number a bit over 800 and is referenced in all documentation as a "c" model.

    The earliest record of mention I have reference to for the mk4 is the july 1991 avid comm news letter. All they show at that point is a covered and painted airframe on saw horses. The august news letter shows a finished plane. John Larsen did a series of articles for kitplanes magazine in which he cronicled the building of an avid flyer. First article was in may 1991.The plane he built at the avid factory for these articles was a "C". The first issue of kitplanes to have an avid flyer advertisement featuring the mark 4 was December 1991.

    I just glanced at the article and the D model was called a mark 4 simply as a marketing condition. earlier mark 4's will have the same engine mount as you will have for the 582 rotax. Later on they developed a mount they called dyna smooth. They also change the air frame at some point as well in the lower floorboard firewall area to accomadate heavier engines. Avid sold the change as a welded add on for existing airframes as well. the december 1995 issue of the avid news letter shows the install of this add on. the news letters are in the same files section as the article you are referencing.

    So if you have the serial number of the kit listed somewhere it will be a place to start.Numbers in the 800's are C's. You do have the taller landing gear that was standard with the mark 4. Looks like an unpainted air frame and engine mount so that is just how they came unless it does have a flat black paint that doesn't show up in the pics. there is a tab on the passenger side of the air frame which is used for the side mount radiator, which is typical of a C model. You have the nose gear weldment which is a plus in some peoples books. As a kit my plane was delivered early in 1991 and is a "C".
    So what kind of flying machine is that aluminum wing in the back going to become?
