Pietenpol-List: Jack- Please explain trim mech

My trim system is essentially the same as Mike Cuy's (whose ideas I stoleshamelessly throughout the project). The only change I made was to move thecontrol lever to stick up through the rear seat bottom (his is below thefront of the seat and moves side to side). I wanted the system to workintuitively, since I need all the help I can get. With this system, movingthe lever forward gives nose down trim, pulling it aft gives nose up trim.The system consists of a horn added to the elevator bellcrank, with a coupleof springs which can be tensioned by moving the lever in the cockpit. Thephotos should make it clear. The large disc with the notches is just afriction lock to tighten the bushing that supports the lever, locking thetrim in whatever position you desire.The system works well. I don't need it much, because my fuel tank is in thecentersection and fuel burn doesn't change the CG much, but it helps whencarrying a large load in the forward baggage compartment.Jack PhillipsNX899JP _____

Subject: RE: RE: Pietenpol-List: Jack- Please explain trim mechJack must also be a fan of Cartalk on NPR with Ray and Tom using the term 'shamelessly'and I admit that I shamelessly stole most of my ideas from others who had builtbeforeme--I am merely passing them along if anyone has interest. The pocket watch ideaandslotted side map pockets were liberated from Ed Snyder's (Round Lake NY) ModelA FordPiet. I find my trim to be very useful having a 17 gallon nose tank but as Jack mentionedhistrim isn't used much unless he fills his nose baggage area. ________________________________________________________________________________
