Hi Pete, My slightly flippant response was not really aimed at you as an individual. I am sure fellow Europa owners are very grateful that you are trying to solve a problem that will benefit others. The general point is that as the Europa company concentrates on newer projects and our aircraft get older we will have to rely more and more on this Matronics resource and the Europa Club to be able to continue to build and fly our aircraft. They are both resourced by unpaid volunteers and they both cost money to run. A minimum of $20 for the forum and =A325 for the Europa Club is a very small contribution compared to the treasure trove of information that is available. It would be sad if we lost either of them because there was not enough funds to keep them going. End of sermon!

Nigel my comments are in quotation marks as replies on this website are difficult to use insertions. Your Comment: You have discussed the aerodynamic pros and cons, but of equal importance is the mechanical consequence of an offset engine. The apparent pitch difference of blade rotating around an offset engine will be double the engine offset. A blade will experience a change from -1.5 to +1.5 so a delta of 3 degrees. Now if a customer of yours came to you with a fixed pitch Warpdrive, and you discovered he had set one blade 3 degrees coarser than the rest Im pretty sure you would send him away with a flee in his ear and tell him to correct it. But we seem quite happy to accept the same degree of blade variance if we offset our engine without question. "The change in pitch of an airplane from takeoff, climb, cruise at differing speeds and descent speeds is more effective change of the pitch than torque offset. We know that propellers are designed to take these dynamic loads. That is why I am not a fan of propeller blades with limited lifetimes of only a few years now being sold. I was able to actually break one of these blades by lying flat on the table and pulling up on the tip and breaking it with my scrawny hands. Good props have very long life, shrug off the elements, bugs, rocks, and are not subject to any concern about the variances in angle of attack, yaw or normal dynamic loads. As an example, think about the downward moving blade and the upward moving blade at a small angle of attack say during climb out. The effective difference between the upward and downward blade is about 5 degrees and the prop just shrugs off this minor gnat of a force. Props are designed for this loading." The constantly fluctuating angle of attack introduces cyclic loading and unloading of the blades which can produce torsional vibration. This is then transmitted to the swash plate and drive pins of the constant speed unit which is not a good thing. A good buddy of mine (and one of your fellow countrymen) has a successful business designing and building custom propellers and wings for the Formula 1 Reno boys. He showed me a picture of one of his custom two-blade fixed pitch props that had failed catastrophically during a race. It was unusual in that it had split from tip to root. All calculations indicated that it should have been more than strong enough to absorb the power; however the prop had failed due to extreme torsional oscillation along the blade length. By working closely with the owner, he was able to establish that the plane builder had offset the engine. A new (identical) prop was made, the engine offset zeroed out and the racer went on to win gold with no further problems. It was during one of our sitting by the pool drinking beer and talking planes sessions that he first asked what I was going to do regarding the offset of my then new Europa. it got me thinking. "A bit of apples and oranges here: Identical prop with only a change in offset on a racing plane is not a good example. One off custom means just that, custom and one must look at the variances in build tolerance. A good manufacturer will have very few defects, but there are still defects so most blades are overbuilt except for extreme needs. Too many ifs and questions on that example as he changed more than one thing, blade and engine angle, which means mounts and cowl and many other little things we dont know about. Blades on an O-200 turning some 3500+ RPM and pulling 4-5 Gs goes through much more than offsetting a prop a degree or so on a small engine. The gyroscopic, pitch change on a racing prop limits their life. More than likely, the culprit may have been bad trim from the start and a worn out prop. Who knows for sure." Now with regard to the suggestion of fitting a rudder trimmer (purely hypothetical as I have no plans to take a saw to my fin), I was a little surprised by the strength of reaction to this suggestion on the grounds of increased drag. I am also curious as to why our attitude to controlling yaw trim is so different to the way we control pitch trim. "I think rudder trim is a glorious idea and feel it is worth the weight and drag from a pure convenience point. Go for it. I too dont want to spend the time. Ive got everything for it for 12AY but I just dont have the time. I even like using springs rather than tabs to just tug a bit one way or the other using a trim motor setup. " The pitch control system uses an all flying tailplane with a (very good) trim system. According to Don Dykins book, during the cruise, the tailplane is constantly flying the rear of the aircraft downwards to maintain level flight. This will be generating drag too but we accept this without question! "Again, the lifting stabilator on the Europa has a drag bucket associated with the small angle of attack near neutral on the series six type laminar airfoil used. The increase of drag for a tail force down is exceedingly small on a Europa. However the change in main wing angle to offset this due to an excessively forward CG will slow the plane down considerable. The aircraft longitudinal stability is more important than the drag as is a more aft CG for speed as it decreases tail down force a bit." When considered against the cumulative drag created by the nose wheel , main gear, outriggers tailwheel, flap hinges, GPS antenna fuel vents, strobes and door handles, surely, the extra drag of a rudder trimmer would pail into insignificance but surely make life so much easier in the climb out or cruise. "I completely agree with that, plus a good pilot is a lazy pilot and a well trimmed airplane, flown smoothly is more efficient in its operation and a delight to fly in." I have re-read my original response to Jonathan and I stand by everything I said. I think the explanation of the aerodynamics is accurate (certainly nobody has challenged it) and my advice that if it ain broke, dont fix it also stands. For every pilot happily flying a Classic with no engine offset and reporting no problems, there seems to be another flying an XS with offset experiencing problems. I suspect that the real explanation is muscle memory. Experienced feet will move by themselves without the owner even being aware. Those with slower feet will find themselves behind the curve. "I am working with Creighton Smith on 96EG, a classic with 80 HP and only inch of offset. It flies fine at 5000/24 inches. Anywhere else on the power curve and he must add rudder. If he had a 914 he would be seeing a different story on the takeoff rudder needed to keep straight and would tire without rudder trim. By the way, he too wishes he had rudder trim. Just not enough hours to allocate to justify modification. So like most of us he just leans on the right rudder if flying at 5500, and left on a 4600RPM saunter. Every experimental is slightly different so one knows apples and oranges are different but are still fruit and a Europa built and equipped by one builder will be slightly different than another. There is little homogeneity in home-made airplanes. Trim it up and enjoy the flying.
