  1. Just did my annual with no major issues. BUT upon my first flight afterwards, I noticed a minor loss of continual power. In other words, my Rotax 912ULS was simply not turning as fast and as powerful as it did just prior to the annual. As soon as I took off I noticed my climb-out was a bit flat. My top RPM (with full power) was around 4750 to 4780. I usually get above 4900rpm with full power and when I level off, I can easily exceed the 5000 rpm if I desired. There were no major issues with the annual ... as I performed all of the following regarding the engine: BTW ... total time: 180 Compression GREAT ... 79/80 all around K&N air filter cleaned (with K&N kit) Spark plugs cleaned and gapped to factory specs Fuel flow test was perfect - both wings Gascolator screen checked and cleaned - no debris or sediment found If anything, I expected the engine to hum perfectly! But it seems to be a bit sluggish. Why oh why? I seriously doubt there is a major problem because the engine runs so smoothly. There are no misses, no weird noises or any unusual vibrations. There are two observations to consider but not sure if they mean anything. On my Dynon EGT digital gauges, two cylinders are monitored: #1 (left side of engine) and #2 (right side of engine). OBSERVATION ONE: #2 shows a slightly lower EGT, by around 100-degrees. OBSERVATION TWO: I am using 91-octane, 10% ethanol blend, that is about a year old (but the plane flew just fine before annual) I would appreciate any thoughts you may have! Tom
  2. By the way, what is the duration between repacks with the factory installed BRS system?
  3. What would be really nice, is if someone ever did an instructional video on removing the replacing the wings!
  4. I believe the "key" word here is "training". When my son got his rating, he was allowed to use the CTLS, all the way up to, the CFI's "dress rehearsal" (around 3-hours), for his written recommendation for the check-ride. For that "recommendation" and the check-ride, we needed to rent a IFR certified plane.
  5. Just on caveat to this ... after you install the 2020 Antenna, go into "set up" and select "SV-GPS-2020" as your "SERIAL IN DEVICE" (see image) for Port 5. Then you must update your transponder firmware to version 2.6 or later (see image)
  6. As a relatively new owner (less than 2-years), I bought my CTLS with 30-hours on it, I need some basic info. What the latest firmware for Skyview Classic? I checked out Flight Design's website and there are no longer any links for firmware.
  7. Thanks. Do you know if that is the exact one that is in our planes? I thought the range is 0 to 15 psi
  8. By the way ... that sender (shown in the photo) does not appear in any of the service, maintenance or parts manuals. There is no reference anywhere to that part or part number. After searching Dynon and Rotax boards and various support forums, I found that erratic fuel pressure is a common issue with "VDO" sending units (like in the one in my plane). Apparently, the senders are unreliable. Dynon (and Rotax) recommend switching to the Dynon Avionics P/N 101690-000 (AKA, Kavlico Fluid Pressure, 0-15 PSI – P/N 101690-000). Here's a pic: You also can select this specific probe in the skyview setup menu. My only concern now ... how to go from a two wire sender to a three wire?
  9. The entire fuel system checks out. I located the fuel pressure sending unit (pictured here). I figure the most expedient way to deal with momentary spikes and erratic readings is to replace it. I don't think the actual pressure is deviating because the engine runs perfectly, throughout all of the abnormal readings.
  10. I know of the many things that can cause drops in fuel pressure, but what is confusing is that mine spikes momentarily.
  11. ON THE TOPIC OF FUEL PRESSURE ... I noticed, more than a few times, my red engine warning light would go on for a second and my oil pressure would spike. The engine ran completely fine during this momentary situation. Then tonight, while flying, the fuel pressure gauge went nuts - but only for 5-seconds. Pressure went up to 12 then down to 3, the back up and back down. It happened very quickly and erratically. The engine never missed a beat. It was rock-steady. I landed and am trying to figure it out. My gascolator (lowest point for fuel draining) does not have a screen in it - never did. The main fuel filter is behind the panel where the ignition switch is attached. It is a very small inline filter. I have 160 hours and it has never been changed. Another note ... the fuel pressure gauge does not technically have a red line on the high pressure end. But it does trigger the red engine light when it goes above 6. Any ideas?
  12. I found out about that link right after I posted the question! Thanks
  13. Since the last time I posted, I have installed the SV-GPS-2020 and also adjusted the settings in the Skyview. Now a very simple question. How do you test to see if everything is operating correctly. How do I know the system is transmitting ADS-B Out data? I was flying last night in Denver and thought I'd ask Centennial Tower (KAPA). "Centennial Tower, Light Sport 888MM just had ADS-B Out installed. Can you tell me if you're reading our ADS-B transmission and aircraft data?" "Ahh, Light Sport 8MM, we do not see ADS-B data in here. All I can tell you is that your Mode C is telling me you're at 6-thousand, 8-hundred feet, and you're in the traffic pattern." What am I missing? Will towers and centers eventually have receiving equipment to see all of this data we are being required to transmit? And, how did you test your installation?
  14. I have a 2011 CTLS (129 hours). I always have more fuel in Pilot's side (left) wing tank, by about 6 gallons. They never equalize while sitting in the hangar. BTW, while on the topic of fuel, how many fuel filters do we have? And where are they located? The manuals are not clear (for me). I found one in-line filter between the fuel shut-off valve and the firewall (behind lower switch panel). As always, I appreciate any insights! Tom P. S. - Love this site. Well informed owners!
