  2. Exhaust diverter to keep fuselage bottom cleaner?

    The flight test yesterday didn't reveal any problems, nor did it confirm the effectiveness of the diversion. That will take 5-10 hours of flying, I think, so it will be a weather dependent "while" before I'll know if it's keeping the belly clean.
  3. how to purchase new rubber gaskets for fuel caps

    O-rings of the proper material should last a lot longer than 2 years, especially since they are not in contact with the fuel. Do we know why they failed so soon, and was it both caps, or perhaps just the left wing cap?
  4. I am going to order some from the O Ring Store, George. I will let you know when I have them.
  5. Does anyone know where to get new rubber gaskets for fuel caps- mine are starting to show cracks after 2 years. George Feldman
  6. Exhaust diverter to keep fuselage bottom cleaner?

    I first saw that sytle of chocks at Ed Walker's hangar. It's made out of 1/2" PVC pipe and two right angle fittings that are glued together - standard Home Depot stuff. They are effective, cheap, and easy to make. I carry one in the glider for tying down when away from the hangar. I can get a picture and dimensions later if you like, but it's easy enough to cut the pieces, fit them together, then glue once the lengths are right.
  7. I like your chocks . They look they are made out of plastic
  8. Exhaust diverter to keep fuselage bottom cleaner?

    I couldn't find an exhaust tip to divert the exhaust flow downward, so fabricated one from a 180 degree bend tubing piece (1.5" OD tubing, 3" radius bend). The Phoenix exhaust tubing appears to be metric, about 40mm OD, so I had find an exhaust shop that could expand the end of the tubing enough to slip over the Phoenix exhaust. The end has 8 slits cut in it, and a hose clamp holds it to the Phoenix pipe. I hope to fly with it tomorrow.

  10. Dynon ADSB-472 and GPS-2020

    I did the same thing, so I contacted Dynon, and they called me today. The support person said they are wrapping up the last of bugs that caused them many headaches the last 6 months, and expect delivery to begin at the end of the month. For me, with an April 2017 sign-up date, it will likely be late Spring/early Summer. He did say if going without one till then would have a big impact to contact them. It's not a problem for me, so I didn't take it further. Call at 425-402-8420 to discuss the details with Dynon.
  11. Dynon ADSB-472 and GPS-2020

    I signed up last April for the swap offer and still haven't received my new unit. I was recently told they would ship at the end of January 2018. Have others experienced this delay, or has everyone gotten theirs? Ted Hauri (Sinus 467)
  12. Upholstering worn seats

    Our app. 35 year old GROB 109 badly needs new upholstering. Any experiences and knowledge available? I believe we had some fire resistance regulatory issues once, but the have been relaxed, as far as I remember.
  13. Hi, Dave This may help. Send me a PM if you have questions. Ed
  14. Power for a camera on the tail

    It's worth trying, but I had issues with a similar backup camera: the field of view (FOV) was so wide, it was hard to see smaller objects that still might be a problem to to taxi near. Even piper cub didn't look close until it was REALLY close! the cables seemed to bring RF noise into the cockpit that sometimes caused noise in the headsets the heat where I mounted it (just behind and below the firewall) may have caused it's slow death after a few months. Inside the cowling is likely even hotter. it was worthless for looking for dust devils and other interesting things ahead and on the ground, a big reason for having the camera - that wide FOV problem. Getting the 12 v power from the engine area means you only need to bring one cable into the cockpit, and that might avoid the RF noise problem. I don't recall trying ferrite cores around the cables - that might also work.
  15. Power for a camera on the tail

    Here's an very inexpensive camera that I purchased on E-Bay to use as a taxicam: http://vi.vipr.ebaydesc.com/ws/eBayISAPI.dll?ViewItemDescV4&item=382072377120&t=1493298335000&tid=10&category=149976&seller=extra-partss&excSoj=1&excTrk=1&lsite=0&ittenable=false&domain=ebay.com&descgauge=1&cspheader=1&oneClk=1&secureDesc=0 My plan is to drill a small hole in the front of the lower cowling and then use the Dynon video interface adapter to display the image on the Dynon display. I haven't actually had any time to work on this, so I don't have any results to share.
  16. I have the 2020 compliant GPS source in my Dynon system as well as the dual band ADS-B receiver. I lucked out as the 2020 compliant GPS source had just started shipping when the avionics were being installed in my Phoenix. I took up Dynon on their trade-in offer for the dual band ADS-B receiver when it came out earlier this (last) year. The install was not very difficult, except for getting at the awkward location of the original receiver, and having to drill a couple of new holes for the mounting screws on the bottom of the glove compartment, as the new receiver had different physical dimensions than the old one. I STRONGLY recommend that you upgrade to be fully 2020 ADS-B IN and OUT compliant. This is a no brainer if you already have a Dynon system, given how economical the upgrades are. Also, don't forget to install the latest firmware updates for the Dynon transponder, which fixes the problem with the transponder going into ground mode when you are soaring at low speeds with the motor off.
  17. Has anyone in the group upgraded their Dynon Skyview Classic (non-touch screen) ADS-B system to be 2020 compliant? Describe your experience or your plans to do so. Happy New Year to all. (Too darn cold around here to go flying for me.) Dave Glosser
  18. Exhaust diverter to keep fuselage bottom cleaner?

    And please, tell us more about the retrofit fuel injection system!
  19. Exhaust diverter to keep fuselage bottom cleaner?

    Hello Eric, The plane is staying in the position without having a tail support in place. We had the plane on the nose for about 10 minutes and there's been no evidence of any leaking. BUT I have to say that Christian has a retrofit injection system installed that might behave differently from the standard carburetor. So I'll add this question to my To-Do List!
  20. Exhaust diverter to keep fuselage bottom cleaner?

    I use a creeper to roll around under the fuselage while cleaning the belly, but it might be easier tipped up on it's nose. Is there any problem with fuel leaking out? Does it stay on the nose without support for the tail? Be sure to ask Martin about keeping the oil off the fuselage with an exhaust deflector, or easier ways to clean of the oil! I don't know if the exhaust flow pulsations would be problem. We know from Russ Owens experience that even the standard system can develop cracks in the exhaust pipe, so I intend to try it, remove it if it doesn't help, and make inquiries about the pulsations if it does help.
  21. Exhaust diverter to keep fuselage bottom cleaner?

    Hello Eric, I'll be 49 U15 in April 2018. I've heard about this issue and have personally seen it on a Phoenix in France. Not sure if your suggestion will work, it depends a lot on the balance of the airflow around the fuselage and exhaust airspeed. I don't think it would effect the exhaust back pressure significantly (still maybe worthwhile to talk to Rotax about this) One thing to watch out for might be vibrations that you introduce through a perpendicular force on the exhaust tube. I've seen Christian Brondel doing the following. Put a cushion below the nose of the Phoenix and lift it on the tail so the nose is gently sitting on the cushion. This provides you free access to the fuselage to clean it. It's not ideal but it works. I'll be with Martin in Feb and will discuss this with him! My thoughts are maybe finding a film that can be easier cleaned and put that on the fuselage. Merry Christmas and greetings from Geneva, Andreas

  23. I get tired of cleaning the bottom of my Phoenix, so I'd like to find a way to divert the exhaust stream downwards; for example, something like the "turn down exhaust tip" in the picture (it's about 9" long, and comes in several diameters). Any idea if this would reduce the oil goop on the fuselage, and not adversely affect engine operation?
  24. The following is paraphrased from an email chain to provide information on rudder and tailwheel inspections. Farhad Saba: I own U15/07. In late July of 2017 my aircraft ran off the runway to the left on takeoff. This is despite my application of full right rudder. I managed to slow the plane down and after the landing gear collapsed the aircraft came to a halt. Thankfully I walked away unharmed. Upon further examination it was revealed that my right rudder did not fully deflect to the right by pressing the right pedal to the floor. However the rudder and the tail wheel could be further deflected to the right by actually grabbing the rudder by hand and moving it to the right. The deflection difference between the right and left is 1/3 of the travel distance or slightly more. Please check your rudder for full deflection before each take off by having someone outside the cockpit confirm full deflection when you preflight the rudders. So to be exact this is the third time I have experienced failure with my Phoenix rudder/tail wheel system as follows: 1- about 2.5 years ago the turnbuckle on the right rudder broke just before landing due to the turn buckle being frozen on the rudder pedal and not turning freely. I landed safely! Jim Lee kindly took off the turnbuckle off of his Phoenix and sent it to me. My mechanic and I had to file down the pedal rod to fit the turnbuckle and ensure it’s free movement. Problem solved. 2- earlier this year my Phoenix ran off the runway to the left after a glider landing ( I had landed the Phoenix even better than Jim Lee) despite full right rudder. 3- after replacing the prop and bottom cowling on my first flight I ran off the run way on take off. Only after further examination did we find out my rudder does not fully travel to the right, which is the cause of the 2nd incident as well. Wishing you all a Merry Christmas, Happy Holidays and a very happy and healthy New Year, Farhad Saba Now from Jim Lee, Phoenix Air USA: The rudder pedal to turnbuckle to cable to rudder in the Phoenix is a very simple and common arrangement shared by many types of aircraft. What is not common is the dual steel rod connection to the tailwheel bracket, each of which can negatively impact the action of the rudder or tailwheel if damaged. Taken as individual parts, it is easy to examine all of the parts that impact the rudder and the tailwheel and determine if the action is free and correct. If the tailwheel bracket is bent or broken, it can produce the scenario which Farhad describes. In fact, this has happened to another Phoenix exactly as Farhad describes. When the bent tailwheel bracket was replaced the reduction of control on the ground was solved. Farhad's suggestion to check your rudder for full deflection is right on, and should be part of every pre-flight inspection. But take this one step further and examine your tailwheel in detail (not on every preflight, but the next time at the airport). Put your aft fuselage on a padded 2' high block. Use a creeper or lay on your back, and use a powerful flashlight to examine the tailwheel, the tailwheel bracket, and the two steel rods which connect the tailwheel bracket to the rudder. Move the rudder to full extension. Look at the rudder deflection decal and confirm that the rudder moves fully as indicated on the decal. Have someone sit in the cockpit and move the rudder pedals to full extension and note the rudder deflection on the decal. Have your A&P or LSRM do this at every annual inspection. However! We have learned that it is difficult or impossible to detect a bent tailwheel bracket unless it is removed from the plane. If you have a hard tail strike, it is imperative that you remove the tailwheel and bracket for close examination. After the recent Icon A5 fatal accidents, the first thing I thought of was how lucky(?) I am that noone has ever been injured, much less killed, in a Phoenix to date. I have lost so many friends in aviation accidents that I have lost count. All of you are to be commended for your safety oriented flying. Martin is to be commended for designing such a fabulous aircraft. Thank you all ever so much. Keep up the good work. Merry Christmas, Happy Holidays, Happy New Year! Jim
  25. Power for a camera on the tail

    The VIRB is a nice unit, but my main interest was a camera with about a 70 degree field-of-view (FOV) mounted underneath (by the gear, say), which is needed for seeing dust devils in flight, and even for "taxicam" use. 120-170 degree FOV cameras make the dust devils too tiny to see well, and you have to be surprisingly close to hazards to see them when using those cameras while taxiing. My camera FOV can be selected as 70 or 110 degrees, and it's supposed to allow 160 degrees, but it doesn't. For cockpit and external "scenic" mounting, the wide FOV are definitely better.
  26. Hi Martin, Love the Phoenix and love the idea of electric propulsion. How practical do you think it might be to retrofit a Rotax powered Phoenix with electric propulsion sometime in the future (like TBO)? Thanks, and all the best with new developments Tim P.S. Apologies for hijacking an existing topic!
  27. Power for a camera on the tail

    Gents, you might like the VIRB camera by Garmin. You can pick up the VIRB elite cameras very cheaply now since they are no longer the latest model, but they function very well and offer the advantage of altitude, speed, and route info on screen from the unit's own internal GPS. They can be managed from a smart phone. A Garmin cable interfaces with your headset and the camera to block out engine noise if desired. It's internal battery gives long run time. The free software, VIRB Edit, is ok for video pudknockers like me but not a world beater...quite simple to use though. I have put a suction cup mount on the interior canopy with good results and have now mounted 2 stick-on base plates for the camera's cradle on top of the glare shield. In that way 2 cameras can be looking at different views. Next spring I'm going to make a camera mount rig to screw into the wing tie down hole. The editing software allows for rotating the image into the upright position. Attached see clip from flight from Princeton, NJ to Bar Harbor, ME. In this one I have the camera in my hand and show the mount. Note the sophisticated airconditioning unit and controls in right canopy vent. VIRB_39n_to_bar_hrbr1.mp4
