  1. If it's a VDO sender then "egauges" or Jegs to order.
  2. "The intent is to show that zero flaps climbs steeper than 15* flaps even if 15 is needed for obstacle clearance" I am always higher at the end of the runway using 15 vs zero flaps. So were the other 7 CT's at my field. The guys that used zero flaps got to the end of the runway sooner, but were lower. I don't often believe what I read and like to do my own research and testing. Many times I find Mfg's wrong. This debate has been coming up about every 6 - 8 months for the last 11 years. It has never been agreed upon, it usually goes for many pages of post and will come up again in several months. It almost doesn't make any difference because each pilot picks the flap setting he or she likes for their own reason and sticks with it. Most all use either zero or 15 for normal take offs and each has a reason why they like their way.
  3. VDO. This will depend on the year engine you have. newer engines use a different type altogether.
  4. Hi Charles, Yes
  5. Each engine may have its own personality. Some may feel more compression than the next guy. Oil burping happens with 4 turns vs 15 turns. Some gearboxes squeak on shutdown and others don't. Some may get vapor lock easier than another.ect.... Don't get worried if yours is a bit different than the other guy's.
  6. Just to get terms right we have alternators.
  7. So I'm totally confused.  I live in Vegas and it's hot hot hot.  I have a 2012 CTLSi.  I want to purchase the larger oil cooler but not sure who I could purchase it from and what part(s) and/or part numbers I'd need to provide the vendor.  I have a local mechanic on the field that will install much cheaper than the local shop.  He only charges $35 per hour instead of $105.  How do I purchase the proper cooler and what information would I need to provide in order to do so, so I can have my mechanic install?  Thank you!

  8. I just got off the phone and I think your problem is fixed. Time for a test flight.
  9. Yep. Only time I had and CPS was happy with. I also have people going to the Fly-In coming for maint. before and after Page.
  10. Note*** When you call California Power Systems to sign up make sure you tell them it is for the Tucson, AZ class in October 2017 or February 2018 so it isn't confused with some other class.. New Rotax 912UL/ULS & 912iS Service Class Conducted by Rotax Instructor Roger Lee in Tucson, AZ In conjunction with California Power Systems Come join us for a new and exciting Service class. Two separate class dates. You can attend either. Oct. 14 & 15 2017 or Feb. 3 & 4 2018 (Saturday & Sunday) This class is a must for an Owner, LSRM or an A&P mechanic to develop their 912 series inspection skills and knowledge. This class will focus on a hands on approach to completing a 100 hour / annual condition inspection. The class will differ from other Service rated classes as it will spend less classroom time and a lot of hands on time with a live engine performing a 100 hour / Annual Condition Inspection. You will be able to ask on the spot questions and solve problems on the live engine while developing and expanding your 912 inspection skills and knowledge base. We will have classroom in the morning Saturday and Sunday ( Oct. 14 & 15th or Feb. 4 & 5th ) and spend both afternoons doing an annual inspection on an in-service and operational 912 engine. The afternoons will be spent in the hangar and everyone will be turning wrenches and performing task. You WILL understand a carb sync at the end of this class. We will have the Maintenance manual out and will follow the inspection procedures. At the end of this class you should be well grounded in the performance of a 100 hour / annual condition inspection. You will receive a Rotax Service certificate for successful completion of this class. Our classroom is air conditioned and comfortable. The hangar is air conditioned temperature controlled with a bathroom. Minimum limit is 4 students with a cap of 10. The class size is limited to make sure everyone gets to participate so don’t procrastinate and sign up now. Class times will be 8 a.m. to 5 p.m. Fly into Tucson International Airport (TIA) or fly your own plane into Ryan Airfield. Classes are Saturday and Sunday. All rental cars are on site at Tucson International Airport or Enterprise will pick you up if you fly into Ryan Airfield. Several hotels are just hundreds of yards down the street at TIA. Ryan Airport (KRYN) is only 10-12 minute drive. The entire experience is convenient and comfortable. For additional information or to sign up call Brain Toepfer at CPS in CA at 951-549-7786 ext. 302 or email For additional class details call Roger Lee in Tucson, AZ at 520-574-1080.

  11. I talked to John today and got more back story. He has something for you to try. I believe you may just have vapor lock and gave him a test to try to rule it in or out. Do this first and quit wrestling with the electrical for a while. Dump all the 91 oct. and put 100LL in it and go fly it.
  12. When it is running what is the mag drop? Normal? If it is electrical it should show up.
  13. One thing to remember in all this Rotax nor an aircraft Mfg can set rules or policy over or under what the FAA has in place. The FAA says you can go on condition and they also checked with the insurance companies and they said they would follow what the FAA had in place.
