    Subject: Tailwheel steering
    From: Douwe <douweblumberg@earthlink.net>
    Andy I personally like a separate set of cables to steer the tailwheel and have been happy with it. I set it up just like bill rewey did. One often overlooked issue is steering ratio. To avoid an overly squirrelly steering response the wheel should turn the same ratio (or even less IMHO) than the rudder. This requires the wheel steering horns be the same length as on the rudder I used a 3" wheel to keep weight down and everyone told me it wouldn't have steering authority and it would wear out real quick but it's working great. I just bought ten at the same time thinking I'd change it each season and haven't changed it after about 75hrs I just don't think we really need these big honkin' wheels back there $.02 Douwe Sent from my iPhone

    Subject: Tailwheel steering
    Ray-I spliced in (nicopress sleeve) a separate set of cables like Bill Rewe y, Douwe, & others have done to the rudder control cables just under the pilot seat and they have worked very well over the ye ars. Be sure to follow the guidelines that Tony Bingelis outlines in his Sportpl ane Builder series of books on the proper selection and installation of aircraft cables and pullies and especially pulley guard saf ety straps/wires when installling these cables (and all other cables as wel l) and you'll have many years of worry-free and trouble-free flying.

    Hi everyone!=0AI'll be traveling to the USA and visiting Brodhead for just one day. This is my second time, first was in 2008 and had a wonderful expe rience thanks to Dan Helsper and his family. This year I'll be there with m y girlfriend Paula and a very special lady, Betty, Dan's mother.=0A=0AAs so me of you know, I'm from Argentina and have been building a Model A powered Piet since september 2004. The airframe is finished and all covered but I' m waiting for the engine to be assembled.-=0A=0AThere are some items I wo uld like to acquire while in the USA. If any of you have a decent set of pl ans to sell, I'll be happy to buy them, mine are very worn-out and I would like to have a new set to preserve. Also I'm looking for two nice goggles ( e.g. Halcyon, Climax). We are not allowed to import things freely here, so I don't mind to pay the full "store" price for these items.-=0A=0AI hope to meet as many of you as possible.=0ASaludos!=0A=0ASantiago

    Just a short clip of what's going on. I took everybody suggestions.....I twisted the tail, added a shim and still no change. Terrible stick pressure to keep the nose up. Re-checked weight and balance and yes it is forward at 15.9" I bought two lead shot bags at 25 lbs each and that's the next step is to put one along side of the driver and see if it make s a change, one at a time. On a funny note, im the only guy with a nose heavy Pietenpol!! should have built the long fuse version! http://youtu.be/o02X2V7F4VM -------- NX321LR Now test flying!!

    You're not the only one. My cg is also towards the front of the envelope. I have a long fuse, Corvair powered Piet. I have my horizontal twisted to compensate. I moved my wing too far back in the build and I think this winter I'll move my wing forward some so I can take the twist out of the stab. It flies nice how it is though. I had the engine shut down on take off due to carb ice while taking my first passenger up (my wife). With the forward cg the nose came right down and was very controllable. We made a safe landing off airport and yes, my wife still flies with me.

    Subject: Chris Rusch stick-nose heavy conditioin
    Chris-forgive me if this has already been covered but your rear cabane stru t is one inch shorter than the front strut yes as the plans show? I agree with Gene that moving the wing forward should help but your 25 poun d bags of shot next to you in the rear seat should be (one at a time as you say) a very good experiment. You're probably one of the few Pietnpol pilots who actually has a very dece nt, even possibly a low, body mass index! I'd gladly fly your Pietenp ol around to let you know what 210 pounds in the rear seat will do for your st ick/CG forces:) ! You are doing GREAT. Your plane is stunningly beautiful, you are breakin g great new ground with that Mitsubishi engine, and your video is excellent and I'm sure it will inspire those new to the list to keep on building! Mike C. Ohio PS- I can send you my diet plan if you like......:) ! https://www.youtube.com/watch?v=o02X2V7F4VM&feature=youtu.be

    HI Mike, Well......first off that not me in the pilot seat, it my mentor test pilot, he very skilled in T/W airplanes. He is only about 150......me, im with the majority at 205. that is what we are trying the weight sacks first before moving the wing or anything drastic. I am using the riblet, so my cabanes are equal length. There was a post about this subject and it shows that the if you lay out the wing incidence, the riblet cabane should be 11/16 shorter in the rear to get the 2deg angle of incidence. if the sand bags don't help, that's what im going to do. Thanks for the nice comments! I still want to try a shorter prop and get the RPM's up more into the power band, but its working fine with the 76 incher I have on there.

    That's the part that is kinda baffling as the weight and balance is perfect......we are going to add weight to match a 200 lb guy in the back and see what happens. If then no improvement, its shorter cabanes and possibly shift the wing back forward. -------- NX321LR Now test flying!!

    From: "William Wynne" <WilliamTCA@aol.com>
    Chris, Congratulations on getting your bird flying. I just read over your notes and would like to share some thoughts. Forgive me in advance if I missed anything you said, but here are some thoughts: 15.9" is not having the CG too far forward. I have plenty of time flying in that range, and as Mike G pointed out, the plane has normal handling there. As the plans note, the acceptable range is 15" to 20". If you are in this range and the plane does not have normal behavior, it is likely something else. If you have a good electronic scale W&B, it is a very easy matter to do an exact calculation to know exactly where the CG will be with a 205 pound pilot. If you have any trouble with this, send me the data privately, and I will do it for you. The whole point to our previous work is so people can do a calculation, and not guess nor estimate. I can not say for sure without numbers, but there is a very good chance that a 15.9"/150lb pilot plane will still be in CG with a 205 pound pilot. If you load up the plane and move the CG back and it flies better at say 19.8", this doesn't mean that the 'problem' has been corrected. It is possible in rigging to have the illusion that the condition is 'fixed', when it has just been masked. If the incidence is not correct, but this is less noticeable with the CG aft, that doesn't constitute a solution, just a mask. If your plane has a different airfoil, than the best advice is going to come from a guy who not only has time with your airfoil, but also the standard one. You need to contact PF Beck and Don Harper. Both their planes fly well, they have motors in your weight category, PF would box as a welterweight, Don as a super Welterweight. (147 and 154 lbs) PF's has the Std. airfoil, Don the Ribblett. Get on the phone with them and ask about their CG, and also the rigging on Don's plane, including the incidence and the position of the horizontal stab. Get a smart level, and measure the stuff in degrees, and listen to the man flying the combination, not the theory of what it should be. A few guys mentioned 'twisted' stabilizers. Am I reading the correctly? or is the comment really about the incidence of the stabilizer? Twist to me implies wash in or wash out on a wing, I am not used to calling anything in the tail twisted. I bring this up because other people may also not be getting the comment. A little work on calculation and direct research with people flying the same airfoil in a similar plane is a whole lot less work than following any suggestion to move the wing some random amount. If, after investigation, it turns out that the wing does need to be moved, I can also show you the exact calculation to hit your new target CG right on. That is more complicated than a normal calculation, but the CG articles we did, available from Doc Mosher, walk you through it step by step. My neighbors 200HP Glasair only did 160mph with full aft stick on its first flight; 3 people from the EAA chapter all claimed the CG was wrong. Actual issue? LE of the stabilizer was off by 5/8". Corrected, the plane does 240 mph. 601XL came to our hangar 2007, aircraft could not be effectively trimmed. Builder was told it was a CG issue by several people. In reality, stabilizer was off by 1.5 or 2 degrees. Corrected the plane flew very well. I have a lot of stories like this, do some research and your plane will get squared away shortly. Follow someone's guess and go on a wild goose chase. Take your pick. Hope to see many of you at Brodhead.

    From: "jarheadpilot82" <jarheadpilot82@hotmail.com>
    Chris, A couple of questions come to mind- 1. How did you weigh your aircraft? Was it actual aircraft scales? Using something like 3 sets of bathroom scales can be extremely error-filed. 2. Did somebody else check your W&B computations? Not to say that you don't know how to do a weight and balance sheet, but I would not feel bad if someone checked my work if I was having W&B issues. 3. Have you read William Wynne's series of articles on Pietenpol weight and balance? I think that they are well written and are backed up by some real numbers, as opposed to guesswork. 4. Did you mention where your cabanes are set? Straight up? Aft? How far? Although I am still building, it would seem to me that cabane height and angle of incidence are not your issues. If you need the W&B articles let me know. -------- Semper Fi, Terry Hand Athens, GA USMC, USMCR, ATP BVD DVD PDQ BBQ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=425960#425960

    You ain't the only one, N92GB is nose heavy with me flying it.- I have- had the shot bags by my butt on many occasions. It was set up for a 230 lbs pilot, I am only 190.- Dad adds ballast in the nose compartment when he flys.- I need to get fatter or move the wing forward, he has only flown a bout 6 hrs in the last 2 years.=0A-=0AShad =0A=0A=0AOn Wednesday, July 2, 2014 3:27 PM, Chris Rusch <rmdinfo@rmdbenders.com> wrote:=0A =0A=0A=0A--> Pietenpol-List message posted by: "Chris Rusch" <rmdinfo@rmdbenders.com> =0A=0AThat's the part that is kinda baffling as the weight and balance is p erfect......we are going to add weight to match a 200 lb guy in the back an d see what happens.
