Thanks for the compliment Rick. You have certainly built a nice looking Piet yourself.I have been following your build for some time now looking for ideas asyou were a lot farther along than me. My performance figures have changed a little from what I first posted. I now have30 hours on the engine and here is what I am getting now. WOT level flight 2800 RPM, just shy of 100 mph indicatedWOT climb out 2675 RPM, 65 mph = about 700 fpm climb at 60 deg2200 rpm cruise = 75 mph2100 rpm cruise = 65 mphThe indicated airspeeds agree with my onboard gps pretty close.What rpm's are you running to get 65 to 75 mph in cruise?Rick SchreiberNX478RSPorter Co Regional, Valparaiso INRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Vertical Offset w/Corvair

Did you guys with a corvair engine offset the front of your vertical stabilizer1/2" - 3/4" to the left like I have seen those with A65 or O200 engine did? Rick Schreiber did you offset yours?

So let's think about this. We're above Rick's airplane looking down on it as he'sflying. The nose wants to pull to the right, so Rick is applying left rudderto keep the airplane going straight. As he presses left rudder, the cableon that side pulls the port side rudder horn and the rudder deflects to port,which causes the tail to swing to starboard and bring the nose straight. Lookingdown on the airplane, it rotates counter-clockwise to bring the nose straight.So what do we have to do to the leading edge of the vertical stabilizer to getthat same counter-clockwise rotation? We offset it to starboard so that moreof the port side is presented to the relative wind, 'pressing' the tail to starboard.The LE of the vertical stabilizer on my airplane, which has a Continentalengine that rotates in the opposite direction from the Corvair, is offset1/2" to the port side but still needs a small rudder trim tab. I think 3/4"offset would have been better, but I worried about twisting the vertical stabilizerbeam too much by doing that.There is a picture of the offset on my LE here: http://forums.matronics.com//files/img_ ... -----Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 power, 72x36 Culver propRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Jerry; to answer your question, I have not done this so, my comments are generalonly. My airplane has a Continental A75 up front.The original Air Camper had the water-cooled Ford "A" engine up front and had theshortest length fuselage of the common variants. Many have noted that moremodern Air Campers have tended to be tail-heavy, and no doubt some of that isdue to extending the fuselage aft of the firewall by stretching the cockpitsor extending the empennage. You say you are rebuilding a long-fuse Piet, so areyou actually reworking the fuselage or are you just thinking about the motormounts and things that are ahead of the firewall? I think your starting pointshould be to research what the weight of the conventional Ford "A" engine conversionis, including radiator and coolant system, and use that as your basisfor comparison. It sounds like you may want to keep your firewall-forward packageat least as heavy as the original, and think about where it's going tomount.The standard Air Camper has cabane struts that pivot at both ends, which allowsthe wing to be shifted aft to correct (or adjust) an aft CG, but only withinlimits.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 power, 72x36 Culver propRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Vertical Offset w/Corvair
