    Scott, does anyone have a accident study for the Pietenpol? I would be interested for safety reasons. In order to live longer I would like to know what to stay away from. IE Don't drink and drive/fly. Flying a piet with no electrics into a thunderstorm is a bad idea. Running out of fuel Water contamination of fuel. Stall spin incidents. controlled flight into terrain Blue Skies, Steve D On Mon, Jun 2, 2014 at 9:08 PM, AircamperN11MS <Scott.liefeld@lacity.org> wrote: > Scott.liefeld@lacity.org> > > Mike, > With that engine and the availability of said parts I don't see a reason > to use the 1/8 inch stuff.

    Steve, Gap seals are not needed with the Frise type ailerons. Take a look at a cub and you will notice that when the trailing edge of the aileron is up, the leading edge of the aileron is actually below the bottom surface of the wing. It works quite well. -------- Scott Liefeld Flying N11MS since March 1972 Steel Tube C-85-12 Wire Wheels Brodhead in 1996 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=424289#424289

    I re-did my heat muff this winter, with much improvement made. Perhaps something similar would work for you. Here's what I did: http://www.eaa25.org/wp-content/uploads/2014/01/OnFinal201401.pdf Carb heat is a lot more effective now, too. - Pat Read this topic online here: http://forums.matronics.com/viewtopic.php?p=424295#424295

    Subject: cooling eyebrows
    I believe I've mentioned this before, but "RE-PIET" began life without cooling eyebrows because I liked the "clean cylinder" look so much. Based on the Rose Parakeet, I omitted the eyebrows, but installed a temporary CHT to see how things went. Long story short, RE-PIET now sports cooling eyebrows and intercylinder baffling. Even in fall temps, the CHT would climb pretty high during a longish climb. I figured that didn't bode well for summer flying so made up a set of eyebrows, installed the intercylinder baffling and have enjoyed worry free temps ever since. That's my story, your mileage may vary. $.02

    Subject: Cooling eyebrows
    Hello good people, I think I touched on this a bit ago, but here goes again. RE-PIET was built without cooling eyebrows because I loved the clean cylinder look. Based on the Rose Parkeet design, a UK piet and some others, that cooling would be sufficient without them. To ck the temps, I installed a temp CHT. To make a long story short, RE-PIET now has cooling eyebrows... Even in moderate fall temps, the CHT would climb too high during a long climb, which made me doubtful they'd remain okay when summer rolled around. I made a set of eyebrows and installed intercylinder baffling and have enjoyed good temps ever since. I've attached before and after pics. That's my story, your mileage may vary. $.02 Douwe

    Subject: Current draw of a White-Rodgers continuous duty DC contactor/solenoid/relay
    In preparing for a long cross country, I am try to determine total electrical power needs for my system (I dont have onboard charging capability). Many aircraft, including my Piet, have a White-Rodgers (P/N 70-11126-5) continuous duty DC contactor that is used as a master switch relay. I think they are common on Pipers and Cessnas. Does anyone know what the current draw is on the low amperage side? That is, how much current is drawn to energize the coil in order to close the heavy-amperage contacts? I guess I could hook up a meter across the master switch poles, flip the switch, and see what I amperage reads on the meter, right? Thanks, Jeff -- Jeffrey H.

    Looks like the coil is 16 ohms at 25C if the data in the link below is to be believed. Apparently 70-11126-5A is Stancor 70-918. Current would be your battery voltage divided by 16 ohms, or about 0.78A. http://www.texasindustrialelectric.com/stancor_relays.asp Ned

    In case anyone is interested, I found the real datasheet: http://www.emersonclimate.com/Documents/White-Rodgers/sell_sheets/R-4003web.pdf Coil is still 16 ohms.
