  1. Opinion it is easy to blame all of the Ducati Voltage Rectifier/Regulator failures on the higher temperature at the 2010 - present SportCruiser Ducati mounting location. And, the late model SportCruiser Ducati Mounting location is, in fact, HOT, especially on the ground with extended taxi times. But if one looks closer at the details, Ducati has produced Rectifier/Regulator units with low quality soldered electrical connections to their internal circuitry. And while low quality solder joints MAY “work OK” in cooler conditions, these lower quality solder connections will eventually FAIL when subjected to heat and vibration . Also, about 2009, Ducati changed the recipe for their internal “potting compound” that reduces electrical components inside the Ducati from vibrating away from the circuit board, to a new black in color potting compound that gets significantly “looser” when hot. This new Ducati potting compound allows the internal electrical components to vibrate against the poor quality solder joints, especially when hot. And eventually the internal Ducati electrical connections will break free. This explains why “pre - 2009” green colored, stiffer when hot, older Ducati potting compound filled regulator units may last longer than the post 2009 Ducati units. Military Electronic equipment manufacturer’s use a pre-delivery Quality Control test called ESS, Environmental Stress Screening, where production units are subjected to accelerated levels of heat and vibration in a factory test chamber to ferret out production quality control problems like poorly soldered internal electrical connections. Low quality solder connections are found and fixed before delivery with this ESS technique to ensure longer term reliability of electronics for the very demanding Military temperature / vibration requirements. Commercial electronic equipment producers (like Ducati) oftentimes do not perform any kind of pre-delivery Environmental Stress Screening Quality Control tests on their production units. The SportCruiser designers can be “blamed” for mounting the Ducati in a hot location, and for arranging the post 2009 SportCruiser installed Ducati’s heat sink fins perpendicular to the cooling air flowing DOWN the engine firewall. A very inefficient heat transfer cooling fin arrangement - the internal Ducati electrical components get even hotter with the first, top heat sink fin blocking most of the cooling air. But if one looks further at the root cause of Ducati failures, the Ducati Rectifier /Regulator has had documented production solder quality control issues, and when coupled with a “spongy, looser” (new since 2009) black colored potting compound, the low quality electrical solder connections inside the Ducati will come loose over Time. There are PLENTY of documented Ducati Rectifier/Regulator failures for Rotax to admit, and then to demand their long time Ducati supplier to investigate and solve, providing a better, more RELIABLE DC Voltage regulator component for their excellent Rotax 912 engine’s Internal Alternator. Of course the SportCruiser Czech Sport Aircraft manufacturer can be blamed easily for mounting a known “heat sensitive” Ducati electrical component in a hot environment. But the current design, as produced Ducati Rectifier/Regulator would not survive long in most AUTOMOTIVE specified Temperature/Vibration Environments. And yet we fly this Ducati Voltage Rectifier/Regulator at night In an AIRPLANE, when our cockpit Avionics and Instrumentation, NAV/Strobe lights, Transponder, ADS-B OUT equipment (if equipped) and Com Radio ALL depend on RELIABLE 12 volt DC power. Improvement ? Options : 1) Ducati production control could Look a little closer at their production line’s solder quality, and change back to the older “green color” stiffer internal potting compound to help units survive longer under heat and vibration. 2) Ignore the Ducati production quality / design problems and we can simply blame the Czechs’ Hot Mounting location for Ducati failures in late model (since 2010) SportCruisers. Dave PS or, Option 3), a third alternative, is for E-LSA Experimental SportCruiser aircraft owners, to buy a Form-Fit-Function replacement Rotax Rectifier/Regulator unit Built by Silent-Hektik. A more sophisticated 12 Volt DC Regulator electrical design with higher build quality, and more robust heat sink fins for reliable use in a hot environment.

  5. Welcome to the SportCruiser forum Todd ! feel free to “jump in” and join the discussions ! Dave
  6. James THANK YOU for “Introducing” yourself on the SCFLIER SportCruiser Forum. Welcome ! very interested in the kit built, Jabiru powered SportCruiser, your new instrument panel, and also the UK Light Aircraft rules. the pictures look great ! Awesome airplane. looks like you have the Dynon Angle of Attack probe under the left wing ? How is your static port done ? I wonder if your engine cowlings would fit a USA Experimental E-LSA SportCruiser/PiperSport ? The large round cooling air holes on front look to be just the thing to cool down a Rotax 912 engine ! Do you know where the original kit builder bought these engine cowlings ? They look very useful ! looking forward to hearing more about your SportCruiser panel Upgrades and incorporation of the GARMIN G5. Dave
  7. SPD2918 WELCOME to the SCFLIER SportCruiser Forum ! The SportCruiser / PiperSport CRUZ S-LSA airplane is PERFECT for a new Sport Pilot ! The SportCruiser is lots of fun for two, easy to fly, economical, relatively fast, has a Proven, Reliable Rotax 912 engine, and most SportCruisers are equipped with awesome Avionics. You will find lots of information on SportCruiser / PiperSport aircraft here on the SCFLIER forum. I recommend using the Forum “Search” function (little magnifying glass at the top right) to quickly find info on topics you may be interested in. If you can’t find your topic already discussed with “Search”, please post a new topic (with your questions) in the “Best Match” Forum outline area (for example Avionics equipment questions in the “General Avionics Discussion” area or a Rotax 912 engine performance question in the “Rotax Engine” area, ....many more Topic Areas in our forum Outline Structure...., ) or, if no “Matching” topic area can be found, use the “Random Thoughts” area to post an entirely NEW TOPIC question or idea. The best way to learn about the SportCruiser line of awesome Light Sport Aircraft is to PARTICIPATE in SCFLIER forum discussions ! good luck with your Pilot Training ! Dave
  8. From Mewp, in Australia, 12/24/2017 ” i, I also moved from GA to LSA for much the same reasons as you are considering. I owned a c172 and found moving to the SC has many similar characteristics, flap ext, cruise speed, approach etc but do test fly one on a hot day. With low weight and inertia you do get bounced around a lot and with the low xwind component and castering nose wheel landings on gusty days can be fun. CSA have improved a lot and respond quickly to any contact I have made. Being in Australia I deal directly with the European agent and they refer me directly to CSA if needed. I do feel it was a good decision and if I need to carry more load or passengers I can hire. My A/C can carry me 85kg my wife 60kg, 20kg baggage and full fuel ”
  9. From NetSurfr, 12/24/2017 ” Hi everyone. I recently joined this forum as I'm trying to learn about the sport cruiser. I'm 50 years old married with an 8 year old and am a instrument rated PP with 450 hours. I own a very well equipped 1979 Piper Dakota that is a phenomenal plane. Although as a family we have used our Dakota for travel wince I bought it in 2014, the reality is that 95% of my flying is just me flying around the local area for fun. I fly out of a city/urban airport with zero good options to land should the engine quit shortly after takeoff or during the approach. Although I know the odds are low of this happening it still bothers me to the point that I don't take my plane out for night flights and I'm increasingly feeling uncomfortable flying my wife and/or kid in the plane for the same reason. A plane w/ a BRS chute would be a solution that would solve my problems so given that my options are to look into used Cirrus aircraft BUT I really don't have the $ to move into a Cirrus especially when most of my flying is local flights for fun. So I started considering the idea of getting an LSA like the sport cruiser and renting a SR22 for the 2 - 3 family plane trips we do in a year. So all that background brings me to this post. Last week I had the chance to fly a 2016 sport cruiser and enjoyed it so I'm planning on getting checked out in it to continue to test it but in the meantime I'd love to get feedback from owners as to your opinions of this plane and the manufacturer (strength/weaknesses and things a potential owner should know). From reading through the threads here I got the impression that CSA doesn't seem to be paying much attention to existing owners when it comes to LOA and I also got the impression the distribution channel is under flux so I'm a bit concerned about those aspects. So again I'd love to hear the good, bad, and the ugly from those of you with experience owning a sport cruiser. Thanks,  Jose  ”
  10. WELCOME to all the Newest SCFLIER SportCruiser Forum Members!! New Members can post an "Introduction" of themselves to All the SCFLIER Forum Members here. Totally Voluntary. If a New Member wishes, they can simply "Say Hello" here, post a picture of their SportCruiser/PS-28/PiperSport Aircraft, or share pictures and unique characteristics of where in the World they are based and fly. Thanks to all the new Members for Participating in the SCFLIER Forum ! Dave SCFLIER Admin PS. Some SCFLIER Members have already posted their “Introductions” earlier, in other various areas of the SCFLIER Forum. I will be moving/copying these posts over here as I can find them and get to them...
  11. I like the “shared Google Map Dropped Pin” idea from Shawn above. Worth a try but only if it includes maps for where our SCFLIER Forum members live: Europe Australia North America South America As a data point, Some Pre-Filtered, based on Participation, “SCFLIER Member home country location” data of PARTICIPATING * SCFLIER Members from August of 2017 Some data on where the current " Participating* " SCFLIER Members are from: Texas, USA: 16, 27 % Not Publicly Telling: 13, 22 % Florida, USA: 7, 12 % California, USA: 4, 7 % United Kingdom: 3, 5 % Arizona, USA: 2, 3.4 % Australia: 2 Georgia, USA: 2 Ohio, USA: 2 New Jersey, USA: 2 Connecticut, USA: 1, 1.7 % Massachusetts, USA: 1 "East Coast", USA: 1 New Hampshire, USA: 1 The Netherlands: 1 Canada: 1 59 SCFLIER Members are "Participating" out of a total of 274 Active Members as of 7/31/2017  * A SCFLIER Forum Member is "Participating" if they have entered at least 4 total Posts on SCFLIER as of 7/31/2017.
  12. Ryan great question and idea. my answers: 1) for the SCFLIER Members added in the last two years or so since I have been Admin, I have some information on where these SCFLIER Forum Members are located - and our SCFLIER Members are NOT just located in the USA. While we do have many SCFLIER Members in the USA, we also have Forum Members who are from Brazil, Australia, the UK, Ireland, France, Switzerland, Austria, ... and several other countries worldwide. 2) for the SCFLIER Members that joined from “the Forum beginning” ~ 2014 to 2016, no records were kept of their home location by the prior Admin. 3) My Policy is to NOT release an individual SCFLIER Member’s Personal Information, such as full name, home address, email address, aircraft tail number, based Airport, etc., without their specific permission to do so. Many Members of a NOT-Secure, Easily Accessible Internet Forum wish to remain anonymous. Other Members choose to Post very detailed information about themselves including their full name, home address, home airport, phone number, email address, aircraft tail number, etc., directly on the forum, for anyone Worldwide to see. That’s OK, but it is up to each SCFLIER Forum member to decide how much and which information to post on the SCFLIER forum. Ultimately, I take SCFLIER Members’ Privacy very seriously, and it is a CHOICE of individual SCFLIER Members on how much Personal Information they may choose to reveal by posting this information on the forum. Perhaps a “Where are you located?” SCFLIER Topic Posting would allow those that are willing to share their home airport location to do so, and this could be useful for your intent of Fly-In’s or group gatherings ....this would allow participating SCFLIER Members the choice to share whatever personal information that they want to...but a high percentage participation is not expected. Out of the 367 total SCFLIER Members, well less than 10% participate regularly ... Dave
  13. Update ! as of today, 10/31/2018, the number of Active, Validated SCFLIER SportCruiser Members with Log-In Privileges is now 367 SCFLIER Forum Members !

  15. Shawn yes, "misplaced discussion topics" can be moved by the Admin, but this is time consuming.... My intent is to help folks on the SCFLIER Forum "self organize" the forum, and take a little time searching for an existing topic already covering their questions, or place their new topic into an existing "best match" area of the forum so that it is easier to find information on topics, and also to minimize my time spent doing chores as your friendly SCFLIER Admin (currently about 10-15 hours spent by me each week). Today's work by your friendly Admin on the SCFLIER Forum is going to be spent updating the Website Software to the latest version just announced by our Website Software Supplier... I am always glad to help, and of course I love the SCFLIER Forum, but I would rather be flying my airplane than moving “misplaced” topics around on the forum... TIME is a limited asset. Perhaps I will have more TIME for “Admin-ing” the SCFLIER Forum another day... Dave Your Friendly SCFLIER Admin
