Dan, That looks very good. Nice and neat. What did you use to wrap the wire bundles? Is it just black electric tape? I have some plastic wire wrap that I bought 30 years ago for the dune buggy I built. I'm using it in the engine compartment just because it looks cool. It's a expandable wrap that is chromed. I may start another fire storm here but a number of my instruments came with wiring harnesses that are colored wire and do not appear to be tefzel. I will use the tefzel on every thing that I wire but intend to use the wiring that was provided with the instruments to the point that there would be a connection to change over. The instruments that came with wiring that I don't want to give up are the Turn coordinator, EIS, radio, and transponder.

I also am using the wires that came with certain instruments. If there was a wire there, I used it. All the rest is that teflon coated MS wire.

They use rotating magnets and electronic modules that switch as the magnet rotates past them. Their setup is for one set of ignition, but you could make your own housing to stack two sets of them. Or an even better idea is to use one of their sets like it comes then get two extra modules and mount magnets somewere else like the prop hub or flywheel. I know one person that uses a set with magnets mounted off the prop hub and it works fine.

Fortunately, a Type 1 distributor will probably also fit a Type 4. Mallory used to make a dual-point distributor for the VW, and probably still does, as well as others. The dual points can be separated by merely adding an extra insulated pole (screw insulated all around with phenolic or whatever) for the second set of points. Then the two poles are connected to two separate coils, which are connected to an MSD coil switcher (I've finally memorized that the part number is 8210). The coil switcher is just two huge diodes that let either coil (or both) supply energy to the distributor cap's center tower. Since some (maybe MSD) don't recommend running them both at the time, the Corvair folks (or at least the one's that abide by William Wynne's conversion manual) hook them up to a double throw switch that supplies 12V to either one coil or the other. That gives you a redundant ignition system with the exception of the MSD switcher, plug wires, spark plugs and the coil wire. It's hard to imagine a properly secured plug wire from just quitting, spark plugs are pretty reliable these days, and the switcher would presumably croak one diode at a time. That's the way I have mine, but I have a double pole double throw (DPDT)switch that is also connected to two separate fuel pumps and two separate batteries, yielding both a redundant ignition system, and a backup fuel system. Wait a minute now...I just reread your message. Do you mean you have 8 spark plugs? If so, you got me! You'd have to find a V-8 distributor and move some stuff around inside (and maybe make it a dual-point)if you wanted a distributor cap with 8 plug wires running out of it. Somebody's probably done it. I'd be tempted to plug those extra four holes and go with four sets of plug wires and four spark plugs, fed with the previously described MSD coil switcher option. And some KR guys opt for electronic ignition on one set of plugs, and mag or distrubutor on the other. Lots of options....what else did you have in mind?

Hurricane Frances has left many areas flooded and wind damaged. It is very cloudy here, and the rain keeps coming and going. Hurricane Ivan is reving up in the Ocean approaching Cuba and is following the same path as Charley, so we may have another one before it is over. I don't think making history this way is a good thing! I for one will have the KR stored in the garage here at the house until Ivan decides what he is going to do, then back to the airport. I will also continue to try to get the inspection done, with the plane here or at the airport. Might need to add a boat to the toys here soon! Seems to be more water than solid land right now.

That time also counts because you intended to fly and legally could. Taxi testing for the purpose of testing ground operations with no intent to fly can only be logged as total time experience, not as PIC. Most people don't do this because they want their single engine & if they have multi multi-engine experience to add up to equal their total time. E-mail off net if you want to discuss further.

I read the NTSB report and a friend of mine went to inspect the wreckage with the FAA investigator because he was familiar with the KR. Seems the guy was on his first flight or two with an instrctor that had never been in a KR and they were way over weight and out of C.G.

I was advised to use the 24KG/M3 polystyrene foam nine years ago when I started building and it has served me well so far. I am now getting ready to build the outer wings in which there will be aluminuim fuel tanks. Although the tanks will be ally, I just can't bring myself to build the wings out of polystyrene foam. The last thing I need is to develop a weep from a hose clamp or something and have the wing turn into an aerodynamically shaped jelly. The only polyurethane foam I have seen is the stuff used in the thermal insulation business. It can be purchased in sheet form of various thicknesses or as a two-pack that is mixed and poured into whatever needs to be insulated. The sheet is very light and ridgid and sands very very easily. When sanded, it forms very fine dust and produces a very good product. What concerns me is the fact that the surface of the product seems to always be shedding this "powder". I would imagine that the surface would seperate quite easily from the glass even if a micro slurry is squeegied into it. It also has the tendency to crush and not "give" when pressed by a fingertip whereas the polystyrene has a certain amount of "spring" in it and will return to its original shape--within reason. My question is this: Is this polyurethane foam the same animal that you guys over there are using. P.S Mark J, I tried to look at the sight you refrenced regarding your wing tanks but all I get is the top pic showing all the necessary tools & equip needed for the job?? (http://www.krnet.org/wingtank/ )Also, how did you secure the tanks to the spars? Sorry for taking up so much bandwidth.

That sounds like the same urethane foam that most of us are using to build our planes out of. Mine is "Trymer 2000", straight from the insulator's business world. It comes in 4'x8' "buns", and they cut it to size and shape from there, or more recently, they spray it into place. That's the stuff!

I started out with a friend flying his RV-4 and he kept telling me his location as being ahead of me by several miles. I landed and he was no where in site. I was beginning to worry when I saw him entering the pattern. Turns out he landed at the wrong airport. :-) To make him feel better I told him I "skipped" three times on landing and if he wouldn't tell I wouldn't either. Yea, right........... Winds 10G16 just off runway heading, hazy, bumpy, but all in all a yeEEEEE HAAAAaaaa kind of day. Two more hours on the KR and four more fliers at local airports. 91.5 and counting. How many days to the Gathering??????

I secured my tanks by installing a piece of 1" aluminum angle from the front spar to the rear spar for the tank to sit on. Put one at each end of the tank. The tank should sit loose on the two angle rest...do not hard mount the tanks. Now fill in the space between the tank and the spars with a product called "Great Stuff". This is a foam insulation in an aerosol can and when cured remains quite spongy. After you do that you will not be able to remove the tanks without cutting the foam out. My reasoning for doing it this way is because the wing will flex some and by securing the tanks with the spongy foam allows for flexing of the wing without flexing the tanks too. By keeping the tanks from flexing with the wing, I hope to eliminate any leaks which could occur at the tank seams if the were flexing. Yes, I am working on my wings. Installing a landing light lens on the left wing right now. Did the trailing edge flox thing on the right wing earlier today.
