Well, let me change that statement a bit: the trim system uses a bungee to apply pull to the elevator bellcrank behind the seat and the trim adjustment consists of pulling on a cord under the seat to change the tension. There is a series of knots in the cord and a slot in the hole in front of the seat to allow the knot to be dropped into the slot when the desired trim is reached. After the initial setup that put "some" tension on the bungee, I've never had to adjust it in flight so I guess you could say it simply applied some "pre-load". My experience in flight has been the same as others have found: when the 16 gal. tank in the nose is full, the nose feels heavier and will drop faster if the stick is let go. Midrange is the sweet spot and when the last few gallons remain, slight forward pressure is needed in cruise but it's hardly noticeable. I weigh right at 150 lbs. most days.

I have a trim control using springs to apply pressure to the elevator bellcrank and I rarely ever touch it, once set. The only time I have to adjust the trim is when I pack a heavy load into the baggage compartment (between the firewall and the front cockpit, where most people put the fuel tank). I did find that when I applied gap seals to the elevators (duct tape), the trim changed. I used to have to carry more nosedown trim. Now with the gaps sealed, I have the trim almost full nose up.

You would have to get the info from him. I have asked him to make some written plans, no luck. ________________________________ Message 4 _____________________________________ Time: 07:39:04 PM PST US From: BScott116@aol.com Subject: Pietenpol-List: Funk engines Great engine -- about 65 HP . Uses inserts and oil line rerouting to lube the drilled crank. Has to be the late counterbalanced crank. Lowell frank is now building a fuel injectd system for this engine. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
