  2. Door Lever Guide Plate

    Thanks for the update.
  3. Door Lever Guide Plate

    Progress report . . . I had a couple of false starts printing my first part (after printing the supplied test part I realized my file was behaving normally). It goes thru a dry run of the first layer. Then I ran a part for over an hour and my back bedroom (laboratory, ha ha) circuit breaker tripped (when I turned on an extra light)! So, now (with all LED lights in my lab) it printed completely as shown below. I just realized that the top flange is about .012" thinner than the original part! That is baffling because the hole pattern appears to be very accurate (and has to be). I'll check out my model and add about .020" thickness to that flange (make it a tiny bit thicker than the stock part). The part comes out looking like a carbon fiber part, but this is made with "PLA +" filament. OK, I'll update when I try a part in my CT.

  5. 406 ELT requirments for Mexico

    BBP Alert: 406 issue comes to a head In the second advisory within 24 hours, the BBP has been informed that a 406 ELT will be required on all aircraft flying in Mexico. There is zero tolerance with no warnings being issued. Additional information has been provided the BBP that as of end of day, June 30, any aircraft in Mexico that does not have a 406 ELT will be grounded. As incorrectly reported earlier, there will be no warning. Mexico states that they have given the flying community over 15 years of extensions to allow time for all to add the required ELT and June 30, 2018 is the final deadline. There will be no more extensions. We are trying to find out more information regarding aircraft in Mexico past that date that do not have the required ELT. As soon as the dust settles on this one, we will do another alert. I repeat, do not take your aircraft to Mexico after June 30 if you do not have a 406 installed. And you might be making plans to move your aircraft out of Mexico if it is there without one…. More to come as we get additional information. jack@bbp
  6. Fuel Sight Tubes

    Roger, it is not a debate about which hose to use. I was simply passing along a tip that might be useful to others.
  7. Fuel Sight Tubes

    Use different hose. Mine never have pinch points and I use Ace Aviation poly. If yours has a pinch point cut a new piece 1" longer.
  8. Fuel Sight Tubes

    I know it doesn't cause any issue other than it doesn't look nice. I have tried long and short lengths, and many in between still with kinking issues. This method seems to be providing a nice clean looking installation.
  9. Fuel Sight Tubes

    I haven't had any issues. I have found if you have a slight pinched down spot it is caused by the length of the tube you cut. Usually too short. That said a slightly restricted spot isn't an issue since this just shows a gravity induced level and not a flow. and always install it in the direction of the tube coils natural bend.
  10. 11th Annual CT/LSA Fly-in, Page AZ Oct 17-21

    John-Olav and Tim, I have just made reservations for both Bryce Canyon and Page - pleasantly without incident - ha! My wife, Billie and I will be attending for the first time with out CTLSi, N814WB. We are really looking forward to meeting new friends and seeing the area from the air. I think you can get our contact info from our registration page, but please let me know If you need anything more from us. THANK YOU for being willing to organize this event!!!

    Another way: use heat to shape the tube. Though it takes some skill to get right, too much and it melts or burns, too little and it still kinks when you go to put it on. Warning: Keep that hot air gun far away from the fuel tank!
  12. Fuel Sight Tubes

    Really good tips, Tom. Thank you.
  13. Fuel Sight Tubes

    I maintain several CT's, and I have done plenty of 2 year wing inspections. I buy my fuel sight tubes from Flight Design USA. I try to keep some on hand, and I used to just toss them in my parts box just like they were shipped. Almost always when installing the tubes there would be a spot where the tube would pinch off a little. It is not enough to keep it from working like it is supposed to, but being somewhat of a perfectionist I didn't like it. I have changed the way I am storing the piece of sight tube that is in queue to be installed next. I am slipping it over a piece of coiled 1/4" tubing. A little silicone spray helps it slide in place easier. It slides off pretty easy. Just remove it from the tubing, cut to length, and install. Another tip is that I slide the tube over the bulkhead fittings and place a witness mark on the sight tube. This way I know it is fully seated when I tighten the clamps.
  14. Tru Track Install

    Both pitot and static should be connected.
  15. I also sent my 2008 TruTrack back for repair. They were great to work with. The issue was that the unit seemed to wander to the left 10-15 degrees before correcting itself. While talking to the good folks at TruTrack I mentioned that my unit had only one tube connected to the back of it. It went to the pitot side. They said that it should have both static and pitot. Anyone else notice this same configuration and is it correct for my aircraft
  16. 406 ELT Antenna Installation

    Well I said difficult not impossible. It can't be done as a ELSA. Experimental R&D would work, and maybe also experimental exhibition. The problem is, unless there is a loophole that I am unaware of, it can't go back to LSA after you install the turbine. Even if you switch back.
  17. 406 ELT Antenna Installation

    Actually I believe there is one way, but it involves a lot of bureaucracy and can't be permanent. Even could do it on any certified aircraft. Would be easy on EAB. I looked into doing something R&D on my 310 years ago but the economy went south , faa was good with it and was ready to help. I don' think my wife would be happy to find a turbine purchase on the credit card. She runs both businesses so I can play with airplanes and she cuts the lawn once a week in the summer and I have a very large lawn ,so I may shelve that idea for now.
  18. 406 ELT Antenna Installation

    Actually it does. For an airplane to be LSA it requires a single reciprocating engine. No mad scientist turbine engines allowed.
  19. 406 ELT Antenna Installation

    Over many years a lot of people only know me as madhatter and not my name. There were many times CHS atc controllers would say madhatter on initial contact.
  20. 406 ELT Antenna Installation

    The real Madhatter has been on Xanax since the book came out.
  21. 406 ELT Antenna Installation

    ELSA knows no bounds. A lot of people think I joke about a lot of things. My father thought I was joking when I said I was going to build a plane in my room in college (he was not happy about that), I flew it home after graduation. Cost is my only barrier. Some think "madhatter" suits me, and sometimes it might but it has been the name of my hat buisiness for over 30 yrs.
  22. 406 ELT Antenna Installation

    I know your joking, but that would make certification difficult.
  23. 406 ELT Antenna Installation

    Talked to ACK engineer yesterday. He told me that if rf passthu test is acceptable he would not have a big issue with putting the antenna in the fuselage, however it would not comply with the regs. He said if it was his personal plane this is what he would want based on his involvment in many NTSB investigations. Now this is only his personal opinion and is not advising others to do it, and he is not representing ACK in this. He said that the regs require that the antenna be mounted on top of the fuselage and that being LSA or experimental does not allow deviation from this, bottom mounting is not recommended however he doubts anyone will notice. I guess I will have to decide what to do when I install a 406, if I use outside mounting it will be on top. Good conversation and great plane. I think there can be a lot of improvements which I will make. I seem to have a tendency to do this on a lot of certified planes over the last 40 yrs, some of my FAA contacts are amused over this. I think a Stuttgard 100hp turboprop would be interesting 😁, I said that to my wife the other day but got that evil eye look.
  24. I'd like to try this again. Can Madhatter please e-mail me at topservice@flightdesignusa.com ? I would like some information from you about the belt material. Thanks!
  25. 406 ELT Antenna Installation

    Hatter, 1) The instruments in the panel are not really in a cage. The signal is probably coming in from under the panel. 2) Testing the GPS receiver in the fuselage is a neat idea. You might need to roll the plane around a bit though, to make sure it is really tracking and not just accepting the last known position as good enough. 3) Putting a transmitter in the fuselage is a really great idea (again, transmission is much more challenging than recieving). 4) I would also be interested in hearing what you learn from the ELT manufacturer. 5) Yes, 121.5 is no longer used at all as an indication of an emergency. The FAA has made this very clear for years. But it is still used by the search and rescue folks to pinpoint your location as they close in on you. This may be significant if you don’t have the GPS interface to the 406 MHz signal - which is a more effect pinpointing system. 6) A more touching story than that of the MKS man you mention is that of young Carla Corbus who survived 54 days after a plane crash in mountains of Northern California. She kept a diary detailing the eventual deaths of her father and mother and her anguish and anger that no one had come to rescue her. Her remains were found by a hunter 6 months later. Her story, widely published in 1967, resulted in the FAA mandate for ELTs. Mike Koerner
  26. Door Lever Guide Plate

    Roger - I need to lube my door latch linkage (annual in process). I figured I would use a greaseless spray lube for the metal to metal joints. But I"m not sure what kind of lube to use on the 3 locking pins that slide in the composite door. I'm picturing a clear grease that I can smear on the pins. But, it needs to be something that will not attack the resin in the composite. I think you already talked about his in an earlier post, I'll go look. About the plastic parts breaking, on mine, it looks like they broke when people were unlatching the door, moving the lever sideways (too forcefully) and hitting the thinnest section of the plate. But, also mine are distorted where the lever rests on the plate when latched closed. I think my CT sat out in some hot summer days with the doors locked. The sun and heat got to the plastic. I wish I knew what the current material is, I think it is Delrin. That is very machinable and I was planning to buy that from McMaster and machine them. I just researched the Carbon Fiber filament. The most popular one is made with 70% PLA and 30% Carbon Fiber. Users love it and say the parts are very rigid. Anyway Roger, as I said this is just experimenting for now. I wanted to try my hand at 3D modeling (again, used Solid Works for my last company) and at 3D Printing (I love it so far, even though my first 2 prints failed on the first layer, ha ha). ET
