Some friends stopped by the hangar and we fired up the new engine. It'srunning in this pic. Looks like I've got some trouble. The pic wastaken on a camera phone. The prop is just fine. Strange illusion.Dick N.________________________________________________________________________________

I use two ground-adjustable aluminum tabs on the elevators of myPietenpol. They are fastened to the underside of the trailing edge witha couple of screws and zinc chromate putty (as used in aircraft floats)is used to seal the screw holes against moisture entry.These tabs are adjusted to trim for level cruising flight when theforward fuselage fuel tank is 1/2 to 2/3 full. With a full tank, theplane is nose-heavy and I trim by increasing power. As the fuel burnsoff (and the a/c becomes lighter), I reduce power as required to trimfor level flight.This works quite well, but I really would like to have a controllableelevator trim tab as a backup in case of elevator control failure. Yearsago, I planned to incorporate one but never got around to doing so. Ihave flown a Piet with such a system and it worked very well. The trimtab was on one elevator only, and was added after the aircraft had beenflown for several years.Graham Hansen Pietenpol CF-AUN________________________________________________________________________________Date: Thu, 27 Apr 2006 22:15:20 -0700

Chris,My tailwheel design is fairly simple but a picture would help much better thantrying to explain. I'm headed to the airport in the morning so I'll get somepictures and post them. It may not be the best idea out there but seems to beworking.Don EmchRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: RE: Pietenpol-List: prop trouble?Date: Fri, 28 Apr 2006 07:22:52 -0400
