Thank you! I wasn't aware of the need to set up an account with ISSUU- I just followed the link on the email from RaAus which advised that the mag was available. Will try again. The print size will still be a problem, though, if in future I choose to download the mag rather than waiting to get home to the print copy.

Sorry, I must be missing something. As we are away from home at present and have 4G available on my iPad I downloaded the mag to read. (There will be a printed copy waiting when I get home). How do you save it so that you can read it a bit at a time, or do you have to download it every time you want to look at a part of it? When I went back to it later in the day it had all disappeared! Also my old eyes can't read it as downloaded - the print is just way too small even with glasses

Gooday Mike Some time ago I posted the full specs of my engine - search "Subaru EA81" and it should come up. I use a stock manifold from an EA82 with a home-made adaptor elbow to mount an SU HIF6 carby as used on Volvo B series engines back in about the 1970's or 80's. It's 1 3/4 inch throat and feeds the EA81 very well.

KISS - "Keep it simple, Stupid" or words to that effect. I have tried to maintain as many as possible of the systems the EA81 operated under when in a car, e.g. cooling (still using standard thermostat and water pump), ignition, crankcase ventilation. I also don't use an oil cooler, just provide airflow over the stock sump. I do, however, use a larger single carby to provide sufficient airflow at the revs required.

The reluctor is just a permanent magnet with a coil wound around it. The rotor has pole pieces rotating in this magnetic field which cause changes in the field, and therefore a voltage spike is created each time a pole piece passes the reluctor. This voltage triggers an electronic switch (the so-called "module") which switches the primary current in the ignition coil. There is no mechanical contact - hence nothing to wear as compared to points. There are 2 wires from the reluctor to the trigger module. The trigger module has 2 wires to the coil primary, the positive one also is fed with 12 volts from the ignition switch. That's it.

Sorry to throw cold water on the use of waste spark ignition on carby EA81's. I went down this path right from day 1 with my EA81 and it took me a while to work out why it would miss fire above about 3500 rpm. Eventual answer? With the reworked cam profile, and the Siamesed inlet ports, the wasted spark occurs just BEFORE the relevant inlet valve fully closes. (Check the valve overlap degrees). This allows the apparently irrelevant spark to fire stray mixture in the inlet manifold, probably due to resonance effects at certain RPM. Hence my previously posted path of points distributor, Hitachi electronic dizzy to Nippon Denso electronic dizzy. If you want my flywheel triggered waste spark setup to further experiment with, you are welcome to it. (It even includes a retard programme for starting). I keep coming back to the KISS principle for engine setups!

Only knew Rob when we were camping neighbors at Natfly Temora, I think 2012. Certainly a knowledgeable, passionate builder, designer and flyer. If I remember correctly he told me he had quite a bit to do with building Foxcon Terriers for New Zealand. He is a big loss to our movement.

Gooday Jake Here's another alternative for the tacho pickup which isolates the tacho from ignition or alternator- a car ABS sensor (mine is off an old Magna) with 2 diametrically opposite round head bolts tapped in to the flywheel. The VDO tachos are easily programmed to 2 pulses per revolution.

7.00 pm ABC news:- "Light aircraft" fatality, 70 yr old sole occupant hits powerlines at Washpool, between Jamestown and Spalding. No other info.

From memory, there's one like this at Temora. It's the hangar at the very end of taxiway Charlie. I was looking at the electric winch setup while waiting for a forum at Natfly a couple of years ago. Give Carol Richards a call to put you in touch with the owner?

After too many puncture problems early on with the thin supplied rib tyres, I put on 15 X 6 X 6 Maxxis golf cart tyres. Strong sidewall, deep chunky tread & no punctures since. Only downers:- on loose gravel they chuck stones at the tail, and on rough bitumen there is zero chance of sideslip. Just land straight!

As one of the many Australian citizens who already has been told we WON"T ever get NBN other than by satellite, and that the eventual system is in the promise basket without a deadline, I will resent having to pay extra for the paper magazine. My preferred option? - have a "stripped down" version on the web, i.e. remove all pictures and advertisements and just post the text content. Make this available to any member who can't download the full version. That way we still get the vital info, letters to editor, etc. without the costs to both expensive downloads and the ridiculous time it takes to get them.

Like everything else, you can get a crook one. As previously posted I replaced a perfectly good Odyssey after 8 years (it's now 10 years and still going strong in a ride-on mower). The new one didn't make 2 years, but was replaced under warranty after a bit of to-and-froing with the Adelaide distributor. HINT - don't say it's for an aircraft! Even though mine is starting a car engine they tried to avoid a warranty claim due to aircraft use.

Thanks for clearing that up, Tim. See you there, weather permitting.

Tim, do you mean Barossa Airshow at Rowland Flat on Sunday 12th April? Seems unlikely that the Barossa Birdmen would also have a fly-in at Truru Flats on the same date.

An interesting sideline to wind farms; When the early farms in SA were built (Hallet, Clements Gap, Snowtown are all close to me) they installed red lights on every 3rd or so tower and flashed them in unison. The claim was that the lights were necessary for aviation avoidance. Driving up Highway 1 at night the horizon consisted largely of synchronized flashing red lights, which drove everyone nuts. At night seeding and harvest times the farmers also found that they lost spacial awareness when going round their paddocks. When challenged about the safety aspects, it turned out that the aviation regulators didn't require the lights and they were turned off. More likely the wind farm companies frightened of litigation? Wind farms built since don't have lights, even though the latest Siemens 4MW turbines at Snowtown 2 come pretty close to 500' AGL at the top of their blade arc. (And they are at the top of the range).

Still looks the same on my laptop, with menu bars on top. Using Windows 8.1 on a Leader laptop about 18 months old.

First 30 hours was in a 582 Lightwing, which taught me heaps (particularly what a rudder is used for) while having lots of fun. Last 650 hours or so has been in the BushCaddy, a well sorted all-rounder. What more do you need?

If you are handy with a soldering iron and can work your way around some simple electronics I can supply you with the details of my add-on VOX for the A200. It's based on a Jaycar Minivox kit plus a couple of extras, mainly switching circuitry which mutes the opposite seat microphone when either seat transmit PTT is operated. It has worked well for 8 years so far. No extra intercom unit is needed and no mods to the A200. PM me if interested.

Have a look in ERSA Special Procedures. It is a prescribed route at specified heights and no, it doesn't include over the top. It is, however, a spectacular flight and well worth the planning required.

And greetings from my BushCaddy R80, a great Quebec product. If the avatar pic was from a slightly different angle you would see the maple leaf on the tail.

Back in 1994 when a newby (if somewhat old already) pilot, I bought a Citizen Promaster Wingman pilot's watch in Chinatown, Singapore for a fraction of list price (about 30% from memory). Yes, it was genuine, it is still my daily timepiece and has only needed a battery about every 3 years. It is much thinner than the current Ecodrive models. Downside - I rarely use any of the multiple functions. Every possible timing task needed is done easier and better by OzRunways and/or a smartphone. Great watch, but overkill in today's world. A disposable cheapie would be just as useful (and buy a good tablet computer with the change!)

Without the benefit of having read the above posts, I tried tonight to do the L1 test. I got to about question 28 when the system crashed, reporting "Internal Server Error" and requiring me to advise the time that this occurred. Also frustrating was the way a new connection had to be established after each question, often taking longer than it did to answer the question. Does Canberra really understand that some of us have super-slow satellite connections and that NBN is a myth in the sticks? I've emailed RaAus asking for an alternative way of gaining the L1 rating, but it now appears that I don't have to do it anyway. Why couldn't they have advised us of this when sending out the advisory email?

I use the wheel sensor fom a car ABS system to trigger my VDO tachometer. The flywheel bolt heads can be used to drive it, or a pair of steel tabs as per Jabiru setup. The tachometer simply needs to be programmed to the correct number of pulses per engine revolution. This setup totally separates the tacho from the engine ignition systems, removing one possible cause of ignition failure.
