    Subject: log your test maneuvers
    My FAA inspector told me something which may interest those of us starting or in the flight test phase. He said to be sure you log every test maneuver as you do it, like "70 degree bank", or "gross weight flown" etc because insurance companies have been known to deny coverage if the pilot cannot "prove" from the logbook that whatever maneuver they were in during the incident had been accomplished before, within the test area. He said even after your test phase is done, you can go back into the test area, do the maneuvers, log them and you're good to go. Seemed like valuable info. Douwe

    Gene; the engine swap is documented on my website, here: http://www.flysquirrel.net/piets/engine/A75.html The engine runs strong and smooth, the swap went quite well with very few hitches, and this will be the first summer I get to fly the A75 in the heat to see how much difference it will make in climb capability.

But that's not the way the FAA looks at it. As far as the legalities are concerned, each aircraft is unique (that's why the builder is listed as the "manufacturer of record" in the paperwork). I mean--that's the point of flight testing anyway, right? To document what works, what doesn't, and how the airplane responded to certain control inputs and weight/balance/power/flying conditions. It would just make sense to log that information so that you'd be able to refer to it later in the life of the aircraft.

    Subject: Re: log your test maneuvers
    Insurance is a fickle business, and they're making most of the rules. I could see the argument going something like: You are the manufacturer; what if (the legal equivalent of cha-ching) your particular plane for some reason has different flying characteristics (such as (in recent discussion), your fuselage is longer, your cabanes are longer, placed differently, or are of a different material, your angle of attack is different; how creative can you get when it's gonna cost you if you don't?). Years back after a training flight, a flight instructor was signing my log book for the activities of the day. It was a standard ASA book, with a pre-printed column right next to the fold for take-offs. He recommended I diagonally split the column and modify it to say take-offs and landings, and log both individually. Sounds ridiculously stupid, right? He'd just heard of a case in which the plaintiff's counsel argued that the defendent couldn't prove the currency of his landings, only the take-offs, and the case was found for the plaintiff. Let us not confuse justice with the law. I think Douwe was given some very savvy advice by somebody who's been around the block long enough to have seen a few lawyer games when it comes to airplanes. Besides, it's not like it's going to cost you a whole lot of time or money, just some regimented planning, which should probably be in your 25+ hours of test flights anyhow.

That's to avoid the loss in payload caused by the wing needing to overcome the downward force of the tail. The reason for the down lifting tail is because if you take a look at a wing alone, it's center of lift is behind it's center of pressure. That causes it to want to rotate nose down when it generates lift. This can also be overcome by carefully controlling the placement of the CG, but it is much more difficult in a small aircraft then it is in a large one. The REAL requirement for positive static stability, regardless of if the tail lifts up or down, is that the lift slope curve of the tail is higher than the wing. That's what contributes to the "self righting" nature of the system. If the lift of the wing goes up and the airplane rotates nose up, the lift at the tail needs to increase at a higher rate to bring the nose down without pilot input.

    Exciting, isn't it, Jack? I have almost the exact same engine sitting in my garage. I got mine about four months ago. Mine is a C-75-12, with a tapered shaft. From what I've been able to gather, the C-75 is physically the same engine as the C-85, the only difference is the operating RPM (2275 for the C-75 vs 2575 for the C-85). The A-75, however, IS a different animal than the C-75. Anyway, I'd have to say you made a good choice. But then, I'm a little biased. Bill C.

    Subject: Circuit breakers
    From: "skellytown flyer" <skellflyer1@yahoo.com>
    if any of you have installed circuit breakers to your coils on Corvair conversions I'd like to hear what you used.I have the coil switcher with 2 coils and 2 ignition switches.but I'm thinking at a minimum I will install individual panel mounted fuses that can be easily changed from the seat.no doubt should get breakers but then I am still a tightwad and with the dual coils if one shorts it probably wouldn't stay reset anyway.what's the opinions? and what kind of amp rating?

    We didn't use any cb's in our piet. We have the dual coil switcher, MSD i think. I'm not positive, but I believe your engine would start to run rough gradually as a coil started to fail, if it quit you always have the other coil, only one coil is hot the other is strictly for a backup. Shad

    I think the only physical difference between the a-65 nad a-75 was the addition of a oil passage drilled in the rods (at the bearing caps) for better lubrication, I also believe that a 65 can be modified to a 75. I looked a buying a luscomb a few years back, and was studying up on it. Shad

    Subject: Re: Circuit breakers
    Fuses and circuit breakers are used to protect the wire not the device. If the wire was to short the current needs to be interrupted so the insulation does not burn. If you are using #14 wire 15 amp would be the max. I don't have it listed in my book but I think #16 wire would be 10 amp. You could use two breakers If you wanted separate systems. As far as current drain on the coils you could check it with a meter. My guess is that a coil would draw less than one ampere. Howdy

    Yes my switcher is also MSD I believe. DJ had it rigged up when I bought the project. I'm going over things and trying to clean up loose connections,un-finished parts and such. mainly want protection to prevent a fire.all of it is right in there with the fuel tank so figure even gliding like a brick is better than a flaming arrow.I'm thinking that a 10 amp breaker of fuse would be preferable to letting a shorted wire burn in two in there. and I do need to verify the wiring gage for sure.Raymond Read this topic online here: http://forums.matronics.com/viewtopic.php?p=290073#290073

    Subject: New builder already needs help
    After years of lurking about the matronics site, going to Oshkosh and dreaming about building an airplane I have taken the plunge. My plans arrived today and I am now officially building a piet. While planning my first order to Aircraft Spruce and pouring over the plans and some builders web sites I have a question about spar size. I have seen several mentions of the spar width of =BE inches and the plans show spar width of 1 inch with some sections routed for weight savings. I was going to order section of spar to aid in rib jig construction and to test fit the ribs onto to check for consistency of my build. I figured I would use the section of spar later for the center section if I decided to go with the three piece wing. What width spar are you using? Myron Anderson Plans in hand and preparing to make ribs.

    3/4 inch spars for me. I think they were cheaper at the time. Wish I would have gone with 1 inch as my ribs were built for 1 inch spars.
