  1. From the website - "In recent years, the new crown pneumonia epidemic has shrouded, but our engines are not infected and continue to conduct various performance tests"

    I must say I especially like to have MY aircraft engines not infected with any virus.

  2. Hi from Australia.

    Looking at your photos link:

    The very first thing I see is that your oil cooler was not the one supplied by Jabiru for that age of engine. My own engine is 130 on by serial number from yours. Your cooler is nothing like the one Jabiru supplied back then. I have 550 hours and near 18 years on mine (not in the same type of airplane).

    The cooler supplied by Jabiru back then was a small generic automotive transmission cooler with 5/16" (8mm) auto transmission hose.

    One of your hoses looks to be way bigger than the other. Hoses are also different to each other.

    Your installation is not "by the book." Some may say "so what? - it's just an oil cooler."  I say you're on your own when deviating from the Jabiru manuals and instructions. What you have there is not standard. I have seen a few non-standard installations go bad, big time. That's all I have to offer.

     

    The more alarming thing I see in a photo of your propeller hub is the use of mixed and incorrect length bolts and nuts - some nuts are short, some are long, some nuts have no bolt thread showing. Silver nuts? They certainly are not the supplied standard AN hardware. I presume they are metric hardware? Fitted to a 1/4 inch imperial drilled prop hub?

  3. MARAP is like an STC for RAAus factory built aircraft - yes.

    It came about (in part) to be able to support older aircraft where original parts (as per the Type Acceptance Certificate data sheet) became no longer available. Listed propellers for example.

    Until MARAP came a long, perhaps the only other option to change prop was a full CAR 35 engineered and CASA approved STC.

  4. Someone I know in New Zealand has a request:

     

    Volkswagen Induction Manifold Heater Assembly:
    I seek help in being able to locate a drawing of an Intake manifold that incorporates an oil feed induction manifold Heater (similar to the one in the Taylor Monoplane Drawings) which also serves as an Oil Cooler – similar to those used in the conversion of Volkswagen Engines by Rogers and Revel for Amateur-Built Aircraft in the 60–80's.

     

    I only have about 3% of an idea what it even is. Sounds like real old technology and anyone likely to have been messing with this stuff might be long gone.

    Any thoughts? Thanks.

  5. Bill, I have done that exact job in Azusa alloy wheels, 15mm off centre was enough for me. No problem at all. Countersink slightly to take off any sharp edges.

    Probably fill the old holes/half holes with epoxy if you can, araldite, whatever you have.

    Moving the hole for the tube valve made the world of difference, Valve finally sits properly, and adding air is no as easy as it's supposed to be.

    I say DO IT!

     

    The general problem seems to be that the TR87 style 90 degree valve tubes do not have the valve in the centre, it's offset. Originally, I did originally start with centred 90 deg vlave tubes, but every one bought since then - same brand, same tube - was offset.

    It's a far better solution I think to modify the wheel to take the normally available anywhere TR87 tubes.

  6. A 9+ month old newsflash?

    There are still plenty of alphas, I think the pool is increasing actually as aircraft de-register for various reasons.

    2anything is not an available mark,yet. Hope the paint has not dried yet.

    8___ only to date (as an initial CASA move to get the program underway) and Xnumber__

     

    In other breaking news, Amelia Earhart is missing.
