I was invited to cast a critical eye on an almost completed Air Camper while on a house-hunting expedition in N. Florida last week. I was an honored guest of noted aviation artist (paintings and models) John Ficklen at his home on St. George Island for a couple of days. His Piet is assembled and rigged and looks like a winner. Lots of little personal touches that will keep spectators busy looking for an extended time at airshows. It's delightful! Although he does have dihedral and a center-section cutout YUCK (sorry Mike) he rest of the airplane is to-the-plans and extremely well done. That's expected from someone who makes historically accurate models for museums and private collectors, I suppose. Anyway, it is a treat for the eye and, as is always the case, it's a shame to have to cover it. John's goal is to have it finished for Sun-N-Fun. A two year build time shows what can be done if efforts are directed to the building board rather than the keyboard .

Good for demonstrating cross-wind wheel Congratulations on the endorsement. You will certainly enjoy having that in years to come, and as I said before, it really makes you a better pilot. ...Edwin ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ Edwin Johnson ....... elj@shreve.net ~ ~ http://www.shreve.net/~elj ~ ~ ~ ~ "Once you have flown, you will walk the ~ ~ earth with your eyes turned skyward, ~ ~ for there you have been, there you long ~ ~ to return." -- da Vinci ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ________________________________ Message 4 _____________________________________ Time: 08:19:55 AM PST US From: Michael D Cuy Subject: Pietenpol-List: John Ficklin's Pietenpol in Florida Larry--- Glad you got to see and meet John Ficklin in person. He's the guy who encouraged me to make a Piet video after sending him a bunch of misc. footage in 1999 to help him along in the building process. He's full of energy and enthusiasm. Here are some photos of his instrument panel and fuselage on the gear and the motor mount for a Continental engine that he sent me last year. (hope you don't mind, John) And way to go John by adding the dihedral and wing cutout. Flop, shmop:)) Larry's Piet is very very cool tho with it's super simple panel and paint job......but we'll have to pass him on the left when heading to Brodhead next summer. Kidding Larry !

Got some small mods to do, 1.. prop to be repitched (only getting 2000Rpm static). 2.. Battery to be moved C of G tad to far fwd. 3.. A.S.I to be calibrated Regards, Norman Stapelberg ZS-VJA (115Hrs) South Africa FASI ________________________________ Message 6 _____________________________________ Time: 02:56:17 PM PST US Subject: Pietenpol-List: FW: Pietenpol News From: "Steve Eldredge" Hey guys (and gals) This my be a repeit, but here is your special invitation! Steve E. ________________________________ From: Dan Duesterbeck [mailto:dbled@ticon.net] Subject: Pietenpol News Hey Steve- I've been trying to send an email to the Buckeye Pietenpol Association to have it posted on their website. I would appreciate if you being a Pietenpol enthusiast, that you would pass it on. Pietenpol Fly-In Brodhead Airport (C37) July 23, 24, 25 Brodhead , WI Chapter 431 Brodhead is looking forward to seeing all new and former visitors to our area. For those that are unable to attend, please follow the highlights of the event through our website. http://www.eaa431.org Looking forward to seeing you all!!

I have one question that I hope will be simply answered. The question is what affect shifting the wing back would have on the proper placement of the axle. Example: For W&B reasons, one shifts the wing back 4in. In theory, this doesn't change the CG much at all, but the center of lift changes enough to allow for us that don't fit the FAA 180lb profile to fit leading edge datum CG limits. Should this also cause a move rearward of the axle? Thanks for your input Kirk ________________________________ Message 8 _____________________________________ Time: 08:45:53 PM PST US From: "Christian Bobka" Subject: Re: Pietenpol-List: Axle Dissertation --> Pietenpol-List message posted by: "Christian Bobka" Kirk, First, let me recommend to you and everybody else we fly balance ships. Who cares what the FAA says about 180 lb people. You are flying the plane and it should balance with you in it. Second, I recommend using something other than the wing leading edge as the datum. It does not make any sense to do so. If you are moving the wing around, then you are moving around the datum . The whole IDEA of the datum is that it is a PLACE THAT DOES NOT MOVE. It is by definition, a fixed reference point. I was at a loss as to what to use until some others mentioned using the bolt on the left side were the front cabane attaches to the fuselage. It seems that people will stretch and shorten the fuselage, shift the wing forward and aft but this point seems to not get tampered with. So let us use it going forth. If people give me good numbers, I will calculate W and Balance for them if they think they can't do it. I agreee that the Leading edge of the wing eventually becomes important because we need to make sure the CG is within the fore and aft limits of the airfoil but we can work that into the calculations later. I suggest that you look in the archives under the discussions on axle placement where one puts the axle at some angle forward from the vetical of about 12-16 degrees with the angle measured at the longitudinal and vertical CG point on the side of the fuselage. I forget what the number is and I loaned the book out on it last night so I can't look it up. You will need to compute the exact point on the aircraft where the CG is when looking at it from the side. This means longitudinal (how far back from the bolt) and vertical or up from the floor (Of course the aircraft is level longitudinally and laterally). You are familiar with the longitudinal CG but the vertical CG is new for most and this can be computed through a method Hank Jarrett posted last week and I posted through Jim Markle where he put it up at: http://www.mykitplane.com/Planes/photoGalleryList2.cfm?AlbumID=185 In short, yes, if you move the wing back, the axle needs to be moved back too.
