  6. Has anybody have any experience using a ceramic coating on the gelcoat instead of waxing or nufinish? Would you please share you experience on cost, application, and ect.

    Zig Zag turbulator tape

    i presume it would be to reduce incidence of the high speed rudder flutter we've talked about before. To limit disruption of airflow.
  8. great information. i have had similar problems cross country in rough air. can you explain or provide a hyper link to the new mode information?

    Zig Zag turbulator tape

    What do you gain with the zig-zag on the rudder and the wings? Is it just a better glide ratio, or are there safety and handling improvements? Has anyone done this? Any comments? what zig-should be used? The drawings show a fairly large pitch for it. And how thick should the ZZ be?
  10. The Dynon Skyview autopilot works well, unless there is vertical movement in the air from thermals, wave, etc., which can cause wide variations in the IAS as it attempts to hold a constant altitude. For those conditions I'd rather it ignored the altitude, and held the IAS constant. That function is not available in SIMPLIFIED mode, but it is in EXPERT mode, so I switched from SIMPLIFIED (probably what most of us are using) to EXPERT, using the directions in the Installation Manual. Easy to do - just a simple selection. I've only flown with the new mode once, using it off and on during an hour long flight. It's not as easy to engage initially as the SIMPLIFIED mode, but easy enough after doing it a few times. Disengaging it is the same button press for both. There wasn't much vertical movement in the air, but it did hold the speed +/- a knot or two as I varied the RPM from 3000 to 4500 rpm. Of course, it would climb at the higher power settings, and sink at the lower ones, though it was easy to find a power setting that maintained (on average) the altitude I wanted. And, it avoided the overspeeding (maybe to Vne?) and underspeeding (going really slow and close to stalling?) the "Altitude Hold" mode produces. I like to hear from others that have tried it, especially if you think I'm missing some potential problems.

    Grob 109 (a) Fuel Cap

    I did not see this post. I have a grob 109B. When i get to my plane I will check. But as a WAG I would think a Volkswagen cap might work from a beetle. brian

    Pitch Control Pulleys, please inspect

    Wicks, Aircraft Spruce and Wag Aero all sell control cable pulleys. If all else fails collect the pieces parts and machine one out of delrin.

    Pitch Control Pulleys, please inspect

    I had pulled the right hand side panel for the center console. I found the pitch control pulleys were past their serviceable life and need replacement. They have cracks and my mechanic touched one and it fell apart. If anybody knows where I can get parts, I would appreciate. brian

    Damaged Spark Plug Threads

    Interesting, when we pulled spark plug one and the bottom threads looked corroded. It looked like this pic I stole from amazon. My mechanic and I thought they were old looking. My engine was rebuilt about 40 hours ago and they used the original plugs. So it sounds like the corrosion was so bad when you pulled the plug it damanged the threads. ūüėě

    Damaged Spark Plug Threads

    Has anyone successfully repaired damaged Spark Plug Threads in a Grob 2500-E1 Cylinder Heads, I am not a favour of Helicoils in Air Cooled heads. The cause of the damaged threads seems to be the Spark Plugs protruding too far into the cylinder. The last few threads get corroded and damaged the threads in the Cylinder Head when removed some months later. Ours it fitted with Bosch WC7D, I am not sure if the original Bosch WB240ERT1 reach was different. The recommended Champion REN30S have the same reach. An Austrailan Gliding Club was recommending putting two copper washers to reduce the amount of protrusion into the cylinder. None of this seems satisfactory.

    Propeller Roller Bearing

    Thank you for the help. I didn't realize the Hoffman parts stop at the pressure plate (that's what they told me). I just talked to Chuck at Ximango and it turns out there's a bearing press fit into an outer steel roller. Note, there's supposed to be a visible gap between the roller and the pressure plate.

    Propeller Roller Bearing

    MT Propellers bought Hoffman several years ago. My understanding is although Hoffman no longer exists, Hoffman parts are still available. I know someone who ordered and got two new blades last year. Don't be in a hurry, though. Contact MT directly.

    Propeller Roller Bearing

    Does anyone know how to source replacement roller bearings that push on the Hoffman pressure plate for the AMT-200S? TIA

    Great reference Jim. Hopefully the link below will take interested folks to the previous discussion.

    Look up Dual Battery Trickle Charging in a past post for info on charging batteries.
