Agreed however this does not support the statement, oft heard throughout my lifetime, that fossil fuels will run out sometime soon - Unfortunately if the demand/need is there, new/fresh deposits will almost certainly be exploited - look what our Gov's are doing with coal right now.

Here was me thinking fossil fuel heating & electrical generating was at the top of the list. Hp for Hp delivered to the drive wheels, I doubt (don't know) diesels are any worse than petrol and may be a lot better. Could that be one of the reasons why all our commercials (inc diesel electric trains) run on diesel , not petrol. We have two Hyundai 130's 0ne 2 L petrol, one 1.6L Turbo diesel - guess which one does under 5L/100 Km around our district and better on a freeway run? Electric cars are far from zero emission/zero polluting when you take into account production & (current) electrical generation and then there is the damage to roads from being a heavier vehicles, more tyre wear (micro rubber), etc etc -

Drove my Sons new Ford Everest recently - not for me Josephine! It has zero personality, is a quiet as an electric vehicle, incredibly smooth, all sorts of driver assist systems, massive computer screen in the centre of the dash, a list of gimmicks that require the computer screen to list/activate - boring as.

KG - "................ fossil fuels will run out in 30 years or so." While I agree that fossil fuel must be a finite resource (millions of years to replace) predictions about its scarcity/running out have, to this date, been vastly overblown.

I'm with Nev on this - white goods ha! open them up and see how appallingly they are constructed, even supposedly up market lines are just rubbish, under a fancy exterior. Its no wonder they fail usually just outside of warranty. As for cars - there seems to have been an over reaction/confidence by manufacturers to the automotive application of computers. My computer understanding is embryonic, however I do have some idea of redundancy - car manufactures would seem to be " loading" a single computer with every conceivable function within the vehicle. This is pure bollocks! The engine & transmission should be on a dedicated computer system, with in built redundancy & " limp" mode. All other functions eg window up/down, windshield wipers, lights, seat movement, etc should be returned to old style direct (no computer involvement) driver control or if a computer must be used it should be separate system to above .

And then many of my pre & flight rituals will be history😢 along with all my lifetime experience/pleasure of internal combustion engines😢

Without experience in all the pre-flight rituals (fuel/oil/pressure's/temperatures/etc)I wonder how a student , training in an EA, will transition into a petrol powered one?

You may have mentioned the following elsewhere ; The ground (-) should be to a ground buss, airframe (where appropriate) & engine via a dedicated ground circuit.

Good-on-yah! Onetrack - close enough. 5 mm ID would have been perfect but I can live with 6 mm. Also my thanks for your kind offer to punch them out for me - my Son has a laser thingy and can cut them (I think) but of course I will have to bring forward his inheritance to sweeten the deal 🙃

Thanks Thruster - EBAY only goes up to 15mm OD - I am looking for 32 mm OD but will take slightly smaller or larger (ID 5mm)

Good suggestion, Where do you get your Nylon/Teflon 1mm sheet?

Thanks Rodger - did you notice the OD?

Hi all, Looking for an Australian/NZ supplier of "plastic" (as in Nylon/Teflon/ Fabric/ etc) gutter/fender washers. ID 5 mm - 5.5mm (can enlarge small hole) Thickness, around 1mm +/- .5mm OD min 30- max 35mm (Can be imperial equivalent) Need X 10 - will purchase extra if required. For wheel pant securing, under large metal washers, to protect paint/glass. Essentra Components have them (PN 17W12580) but unsure from where they are coming from (shipping$$) and how long that might take. All suggestions welcome

Hi Marty, If you go on the Autoparts web site https://www.norma.net.au/products/hose-clamps/norma/normaclamp-fbs-constant-tension-springband-clamps/norma-fbs-constant-tension-springband-clamps-packs-of-10- you will find they price list for the Norma Spring Band Clamps - way more expensive than the ICONs through Interpart BUT of more interest is the Norma FBS Clamps Tech data pdf therein. Open the pdf and check out how to size the clamps for your application. My local Interparty store supplied my boxes of clamps (x10) for $18. ? at the store. Note the sizes I have given above for the ICONs - The OD on my radiator hose was 32 mm, however I found the part number CLS -032 to be a bit small. The CLS- 035 is a better fit. The small coolant hoses top/bottom of engine will likely have a 25 mm OD so ICON part number CLS- 026 may be your best bet. If you don't have a pair, I would advise getting a cheap (Toledo) set of purpose made "pliers" - makes fitting/removal a doddle.

Spring Band Constant Tension Hose Clamps can be purchased , through Interpart auto parts at a very competitive price. The bands are made by ICON SERIES. Rotax 912 25 mm cooling hose will likely use PN CLS-035 . The smaller hoses CLS-026 (DOUBLE CHECK befog purchase). The down side is the minimum purchase is a box of 10

I can understand that an aircraft, using a Rotax 9 (or larger) & achieving high annual hours (say over 400) might benefit from such a devise but your average privately owned aircraft struggling to get to 100hr/annum.???? If you go by Rotax recommended oil change intervals (ULP), this is one change per annum. Even if your a obsessive personality like me this is only 2 x 50 hrs changer per annum. The addition of a quick drain to save a few moments (probably less than 2-3 minutes/oil change) will: drain your wallet add weight increase complexity introduce a potential failure point Your choice of course but I wouldn't fit one to a mower, unless I was doing weekly oil changes.

Hi OK, I must confess my "wizz-wheel" skills have not been practised in quite some time, so would now be unfit for the dynamic environment of the cockpit. I use a hybrid of new & old - I still plan my flight on a map, draw in the track but use OzRunways to generate the information that gets noted thereon. I fly with the map(s) open & continually cross check with OzRunways. As part of my routine, I periodically note heading (on the map) and note my whiskey compass reading compared with the Dynon/GPS. I find the Dynon/GPS keeps me on track but the map enhances my wider perception/view (have abetter understanding of where I am, rather than just accepting the EFB knows where it is). Its easy to see mid distant features on the map, that are off the screen, which also enhances the experience and may help with "placing" other aircraft when I hear a call. I have always flown IFR (I Follow Roads & other significant geographic features) so am comfortable with ticking off each landmark/waypoint as they come/go.

Aaaaah! I would need a lot of time to work through your argument RF, so I unconditionally capitulate in the face of superior knowledge, or argument, whichever you prefer😕

So when the gizmo knows where north (or any other point on the compass) is how come it cant figure out - I'm a bit out here, need to adjust by a degree or two, cause if north is there, then west must be a bit further around (or closer)? ie do the compensating based on a known direction, after all that's what the pilot is expected to do when compensating for a known error in a "whisky" compass..

While I can understand the rational of repeating a callibration, so as to acheive more "data points" I am still not convinced that every cardinal point should need to be aligned, to have a modern compass (magnetometer) calibrated . The instructions for calibration of my Dynon, required the four cardinal pints, so that is what I have done -- makes little sense to me. The combination of magnetometer & GPS, should deliver a degree of instant accuracy (without sextants) , that navigators of just a few years ago could only dream of.

Isn't Dick Smiths airfield close to Gundaroo?

Great response BUT; While a magnetometer may have ways of accommodating the non liner characteristics of an aircraft moving through a flat 360 degrees plain , I don't see how a compass can be adjusted to make the same accommodations. The best you could hope for is noting the variations (assuming consistency) at each cardinal point, so that when turning you know to allow for the variation.

So you to sinners don't have a simple answer for me? RFguy may have more to say

I have a very small (two systems) amount of experience with EFIS compass swinging - Both required all four cardinal points to be entered - WHY? Surely the electronic gizmo can work out 45, 90 & 270 degrees from one set direction? Okay, do one additional cardinal point, as a check - should be enough. Anyone like to explain? (simple language please)

Just passing on information from Rotax Owners Forum - make of it what you will.
