  1. Two questions I have, maybe you can help. Two different planes but same avionics in both. I used to have a wind speed arrow that was on the D120. Somebody messed around and now it is gone. I was told this was controlled by the D100. I have searched in both the D100 and D120 trying to find it without success. Anyone know how to do it? The next one is the stall horn setting. It goes off on one of the planes on take off and way too soon on landing. We don't use this plane for check rides because the examiner would hear it and it is just too soon. Can't find that setting either. Thanks

    Air speed gauge

    The round air speed gauge shows 40kt when on the ground and builds from there when flying? Is there an adjustment or what can I replace it with. Digital air speed is fine and if we are at 100Kts the round one shows 140 kt

    Not sure what brand it says Flight Design on the face.

    We are getting close to the deadline. What is the solution for the CTLS? UAvionix on the wingtip won't work and now I have found out that the taillight unit won't work either. Apparently the carbon fibre blocks the wing tip version and makes it unreliable. I tried to install the tail version and the mounting holes are different. The taillight on the CTLS uses angled mounting holes and are further apart than the UAvionix unit. The unit needs to be mounted with the fin on it vertical and using the mounting holes would have it a about a 41 degree angle. They have no plans on revising the mounting bracket to make it work. I have one I was going to test for them but now I need to start looking at something else.

    Brake stuck

    It seems that the best way for you to understand the way it works is for you to disassemble it all and get the complete picture. It is not difficult and will be easy to understand. I question why you are not having an A&P do this for you. If you don't understand the mechanics you may cause yourself a pick problem.

    Brake stuck

    Don't just take the pads out and replace. Remove the wheel and disassemble everything. Clean it all and repack the wheel bearings. Replace the pads and reassemble.

    Brake stuck

    Those are Marc brakes from Italy

    Brake stuck

    Many time it is because the pads are very worn. It can also be the caliper is so dirty things hang up. I would start with those and see if it is all in good shape.

    Fuel caps

    Who has the secret to fixing leaking fuel caps? I have replace both the large and small o rings and tried adjusting several times but still they leak. Short of not filling the tanks so full I don't know what else to do.

    Fuel caps

    My vents are in the wing tips. We sometimes do have the tanks pretty full but even then it shouldn't happen

    Fuel caps

    I checked several times and it is not the seal around the ring. This is happening on all 4 CTLS's we have and it is worse on some.

    Heater control Removal

    Not too difficult but you may need to find all the parts first if you aren't careful taking it apart.

    Heater control Removal

    You can try some penetrating fluid. If they are glued it would require a little heat. Be careful if you are going to try with a pliers on the shaft an the knob. They do damage quite easily.

    Heater control Removal

    The knobs unscrew from the shaft.

    Fuel filter

    Does anyone have a source for the inline fuel filter that is behind the instruments and right before the shut off valve. I think they are replaceable and not serviceable, is that correct?
  16. Has anyone figured out why the straps do not hold tight without tying in a knot. Is it the buckle not being sharp enough to bite into the strap or is it because the straps are old and getting hard. Tying in a knot works but it is a real pain when trying to adjust it.

    Soft Start

    I recently discovered that all four of our CTLS had soft start on them but none of them were hooked up. I don't know why they came that way new but we now have them wired up. How was this discovered? Well one was having some starting problems and in the process we found that soft start was not wired. This is a 2010. We then checked the other 3 and none were wired. They are now. These 3 are 2008 and 2009. As for the starting problem, well not so good. Tried everything and decided the sprage clutch was the problem. Pulled the engine and sent to Leading Edge. Yep clutch was bad but there was now so much damage it was not economical to repair. Time for a new engine. Only 2805 hours. Ran good with excellent compression, just had starting issues. Lots of spare parts now. Might be a good idea to check and see if your soft start is wired in before damage occurs. Easy to tell if it is working because when starting and at idle the engine will start at around 1600 rpm and after 5-10 seconds it will jump to about 1800 rpm without touching the throttle. If it does not increase rpm then your soft start if installed is not wired in. The recent increase in price for the new motor brings it to almost $20,000.

    Soft Start

    I agree also. It does not damage the engine but it does damage the sprag clutch. It is expensive to do the repair and I don't think it is worth sticking the money into the engine at 2800 hours.

    Fuel filter

    Roger is the ELT just checked for operation and batteries? Is there also a test that needs to be done by an aviation shop with special equipment?

    Ignition modules

    Is there a way to test the ignition modules. I replaced both but highly doubt they would both go bad at the same time.

    Removing Dynon HS 34

    Found out that if you have a Garmin SL 30 and want to remove the HS34 it is not so easy. So I am going to relocate the HS34 and keep it. Simple to change from a Garmin 496 to the 696

    Removing Dynon HS 34

    When I switch from the Garmin 496 to the 696 I will also be removing the HS34 HSI EXPANSION MODULE. Can I just remove it and ts wiring?

    Flat tires

    I have had a couple of flats and came up with a way to jack up the wheel when I am alone. I am now carrying my fix in the floor compartment all the time. There are a couple of pictures attached. I made it from 3/4 square tube and welded a 9/16 bolt on the tip. It works very well. I insert the pin in hole on the back side of the wheel and rest one leg against the ground. I can then can lift one wing and the stand will rotate down and I can set the plane down. This leaves the tire elevated above the ground so I can remove and repair or replace the tire. When the tire is replaced, I simply roll the plane forward and the stand rotates putting the tire back on the ground. This one weighs about 3 pounds. My next version will be aluminum to save some weight. I also carry two allen wrenches for removing wheel pant screws but I will depend on the other tools needed being on location as they are common tools found in most hangars.
  25. I made it when I had the small tires. Now with the tundra tires I have added an inch or so to raise it a little higher so the tire clears the ground. Put in the hole in the back of the wheel then go to the wing tip and lift until it swings down. The plane will sit with the tire in the air. If you modify it and angle the legs in toward the center it is then very easy to grab one leg and push the plane to get the tire back on the ground after the repair.
