    Subject: Model A Question
    Model A guys and gals, What kind of water temps have you been seeing in flight? Also I had my timing set around 25 degrees BTDC, and have found it turns up more RPM's and even runs better at about 18 degrees BTDC. Is this in line with others? I do thank you for your time.

    Subject: finishing the discussion on tailwheel cables...
    Hello Piet Group, A couple of weeks ago, something was mentioned regarding the ground handling of a Piet when the tailwheel cables are spliced onto the rudder cables. I was planning on doing just that on my project, locating the splice under the rear seat. Are people aware of any safety concerns by splicing these two controls togather? I am trying to realize if there is any difference in splicing or running the two sets of cables to the same points on the rudder bar. Let's assume a full swiveling tailwheel will also be used on the system. Thanks all, John --------------------------------- Building a website is a piece of cake.

    John, I have tailwheel steering with a cable each to the rudder bar. Both are adjustable and two takes up very little more room than one. I have a set of pulley=92s under the rear seat back to allow for the change of direction (rudder up and tailwheel down). That=92s it. I toyed with the idea of splicing but decide on the two cables after not seeing any advantages of the spliced control cables. HYPERLINK "http://www.cpc-world.com/new_card_images/images/IMG_0213_JPG.jpg"http:// www .cpc-world.com/new_card_images/images/IMG_0213_JPG.jpg shows the pulley=92s. HYPERLINK "http://www.cpc-world.com/new_card_images/images/IMG_0263_JPG.jpg"http:// www .cpc-world.com/new_card_images/images/IMG_0263_JPG.jpg shows the exit points for all control cables. From the top they are top elevator, rudder, bottom elevator, tailwheel.

    Chet, At Brodhead Ken Perkins recommended 30 degrees BTC timing on the Model A. He has a lot of flight hours behind one. I am surprised to hear you say it revs up better at 18 BTC. I have no experience yet, but I plan to run mine within the next 6 months. I would like to hear from others on this issue. Dan Helsper Poplar Grove, IL.

John, I didn't like the idea of messing with primary flight controls, and the tailwheel will turn too much if it is the same ratio as the rudder, unless you have very long horns on the tailwheel. I ran the 1/16" cable from the tailwheel, all the way up to the inboard portion of the rudder bar - not the same point as the rudder cable. If need be, can adjust the points where the tailwheel cables attach to the rudder bar. Here is some pics - _http://nx770cg.com/Unique.html_ (http://nx770cg.com/Unique.html) Chuck G. NX770CG

    Subject: Re: finishing the discussion on tailwheel cables...
    As I said in the discussion a couple of weeks ago, I feel that the tension put on the cable, by the tail wheel, caused a shift in the rudder position when the tw came off the ground. That was causing the plane to veer suddenly to the left on takeoff. Not a problem since I ran seperate cables.

    Would you send me a picture of that when you get a chance. harvey.rule@bell.ca or harvey.rule@rogers.com or just post it on this web page. I was going to do this but when I figured I had to cut the cables to do the splice, I thought it may not be a good idea. I'd like to see how you did yours.

    Thanks for the good information on my tailwheel cable concern. I have decided to run the cables right up to the rudder bar after reading the reasons to do so. I think all the reasons are valid, especially ground handling and "not messing with primary control cables". Thank you all.

    Subject: Mountain Piet Axel Question
    From: "Catdesigns" <Catdesigns@comcast.net>
    Does anyone have a good picture of the front and rear spreader bar where it attaches to the landing gear V on John Dilatushs Mountain Piet currently owned by Greg Bacon? Greg, are you still on the list by any chance? This would be a picture of the inside of the bottom V. I am trying to figure out if John used the plans method of attaching the rear cross tube (using one bolt) or did he weld on a plate to the end of the tube and used two bolts. I am copying Johns method of stopping the axle rotation during braking but I am concerned the rear cross tube might rotate if anchored by one bolt. All John had to say on it was to weld on some 3-inch tabs to the axle and the cross tube. He advised making the rear tube thicker wall so I would not flex as much. He never mentioned changing the mounting of the tube. I have a few more questions for anyone who might have inspected his setup in person, such as thickness of metal used for the tabs welded onto the axle and cross tube and the dimensions (as in 3 inches above and below or three inches total. If someone has a good picture of the tabs and connecting links that would help. The only ones I can find are from Oscars website. http://www.flysquirrel.net/piets/John_piet.html Thanks Chris -------- Chris Tracy WestCoastPiet.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=136567#136567

    Subject: Re: crankshaft
    Thanks Chuck but mine was already .010 under. When i had it overhauled a while back (40 hrs ago) the crank was just barely within limits. The camshaft had wore odd so we put the case back together and lo and behold the case halves did not line up at the center bearing and at the back bearing. I had the case overhauled which included line boreing. so maybe it was'nt right to begin with or I'm sure the overhaul shop will tell me i must have gotten it very hot to cause iyt to warp. I truly do'nt believe we ever had it that hot. The good news is that i might have found a crank that just needs ground. I really think i just need to sell the Champ and then i'll get serious about finnishing the Piet.

    Subject: A 65 exhaust
    My A 65 muffler gave up the ghost this past weekend and today I took it apart and found it to be beyond repair. I'm thinking about changing and running without a muffler and putting a heat muff on. Has anyone used the Aeronca exhaust on their Piet? Wondering what others have done and where they found the exhaust parts to do it with. Any photos would be appreciated. Thank You Gene

    Gene, I didn't use a muffler. I just made up flanges and went to my local muffler shop for 1.5" mild steel tubing and weld up some straight stacks. Added a carb heat muff to the right side.

    Gene, The heat muff is 3" diameter exhaust pipe. It has two 1.5" holes drilled through to slide up the two straight pipes and welded in place. The back side of the muff is closed off. A tube is welded into the side with a duct attached and running to the heat box. I heated and somewhat squared off the front of the muff to try to get about the same area of inlet as outlet. Let me know if you would like more pics. Don Read this topic online here: http://forums.matronics.com/viewtopic.php?p=136665#136665
