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.Chet HartleyN920Y, Missouri________________________________________________________________________________Date: Wed, 26 Sep 2007 05:26:36 -0700 (PDT)
Pietenpol-List: Model A Question

John,I have tailwheel steering with a cable each to the rudder bar. Both areadjustable and two takes up very little more room than one. I have a set ofpulley=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 splicingbut decide on the two cables after not seeing any advantages of the splicedcontrol cables.HYPERLINK"http://www.cpc-world.com/new_card_image ... 13_JPG.jpg shows the pulley=92s.HYPERLINK"http://www.cpc-world.com/new_card_image ... 63_JPG.jpg shows the exit pointsfor all control cables. From the top they are top elevator, rudder, bottomelevator, tailwheel.CheersPeterWonthaggi AustraliaHYPERLINK "http://www.cpc-world.com/"http://www.cpc-world.com _____

Subject: Re: Pietenpol-List: Model A QuestionChet,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.

I am trying to realize if there is any difference in splicing or runningthe two sets of cables to the same points on the rudder bar.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 youhave 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.
