Subject: Pietenpol-List: Tail wheel cables to rudder barHello Mike B. Swaging the tail wheel cables to the rudder cables is thesimpler way to do it. What would make you want to bring the cables tothe rudder bar instead? Another interesting note: In the old BPANews, awriter suggested connecting the tail wheel cables to the rudder barabout 4 inches out from the pivot. Said if connected at outer end ofrudder bar you over steer the tail wheel. ? Leon S.________________________________________________________________________________

Re: Pietenpol-List: Newbie question: Rudder Bar versus Pedals
Original Posted By: Isablcorky(at)aol.com
Hello Group,My Piet has been flying for thirty years this month with Cubrudder pedals in the rear and a rudder bar in the front. Thisprovides a closed circuit where the rudder bar prevents over-stressing the rudder horn when one stomps on the pedals. I put pedals in the rear as a matter of preference and not forany technical reason. The rudder bar as shown in the plans would be fine.My tailwheel steering cables are 3/32 inch 7x19 and extendfrom the tailwheel steering horns over pulleys mounted on the lower crosspiece directly below the front horizontal stabi-lizer (tailplane) spar. From there they run directly all the wayto the rudder pedal, sharing the attachment with the ruddercable. I don't like attaching the TW steering cables to the rud-der cables in the aft fuselage because they deflect them andproduce wear on fairleads (and the cable itself at the fairlead).Someone mentioned that TW steering cables attached to a rudder bar should not be attached to the rudder bar ends inorder to avoid tailwheel oversteering. A valid point! However,when attaching these cables near the center of a rudder bar, one would have to be careful to avoid interference with the ot-her controls (aileron crank arms on the torque tube, for example).Cheers,Graham Hansen CF-AUN________________________________________________________________________________
