I did mention : My Sonex Legacy has been undercoated/treated, during the fabrication/pre assembly stage, using the following spayed on products: External: DeSoto 51X349 Internal: Alodined,/ BMS10-11 As I was not the original builder of my Sonex, I don't know what the selection process was for these products however I am assured they are both excellent anticorrosion coatings for aluminium aircraft.

You talking aviation or automotive oil? I believe aviation oil is certified. Certification requires that the oil be sampled periodically(??) to determine that it meets the standard/or not. If its Av oil it will have a date on it.

Thank you for your generous invitation. It would be great if a "gaggle" (number of small aircraft flying in company) could be formed. More fun & safety in numbers.

Had a good time plotting you trip on OzRunways and taking in your comments on fuel, weather related change of plan, etc. Please confirm: - You refueled/topped up X 4? Managed to avoider using AvGas? Did not land at any security (ASIC) controlled airfields? I fly a newly hatched Sonex Legacy/Rotax 912ULS, cruise duration (at 75%) is about 6 hrs, with 45 min reserve. Should be enough to, safely, get from one refueling field to next, without stress. Your X wind advise is particularly germain, my aircraft is a tail wheel & I have low hrs in it. My planning has changed often with Serpentine always being the final destination. Sometimes I follow the southern coastline of WA all the way round, alternative up to Kalgoorlie and then west. I have various routes across NSW however SA has remained fairly consistent (mostly following your track). My return has been following the railway line, via Forrest - fuel consideration, seems to be a lot more challenging but weather more consistent inland compared with coast????

Hi Philster, I realy appreciate you taking the time to write out your trans Australia schedule & experince along the way. When I do my trip to Perth (Serpentine??), I will be departing The Oaks (SW of Sydney) just a few Nm further east than Wentworth, but asides from that, your story provides excellent information & invaluable advice. I will use it to update my OzRunways plan. Thanks again.

Technology/systems change - humans, mired in habit/comfort zone, are often reluctant to adopt - just an unfortunate fact. Your past/current experince, with highly toxic materials should have taught you, that personal protect equipment (PPE) is considered to be the last resort in protection, after all alternative safer options have been considered & rejected. "I am not a cheapskate..." No one suggested you were a cheapskate. "I do the right thing for the right job to be as efficient as possible." I would hope we all aspire to this. How is this relevant? "I was asked for my advice.." Yes and generously gave it. I did the same, offering an alternative hopefully safer product - you challenged my advice/experince - "Iso is no where near as good as acetone". No problem. I just happen to think you are wrong. "...I will do as I want to.." and I will support your right to do so - goodonya! "...still laive & kicking" - yeah! another favourite, comforting statement by those unwilling to contemplate another possible way. Well we all know of/heard of the person who smokes a pack a day and lived to 100 - Unfortunatly an exception does not a scientific/statistical probability change. ".....why would I think I am a hero????" Not so much a hero but making what I would consider to be a heroic/bravado argument. Your words/statements - "...don't be a pussy....- I use much more carcenogenic liquids..... - Use the best stuff for the job. Anything can kill you" "I really dont care for your opinion on it either way".. Abundantly clear my friend - why respond? "...this is my opinion and I dont have to explain it to you or anyone." True - but you seem to be😎 "Do what ever you feel comfortable with." Thank you "Mark." - My unreserved apologue - you use my nom de plume, yours is Kyle Communications, out of respect, I have referred to you thus. In future I will use Mark😈

No offence Kyle but why use a nasty to you & the environment product, when something else just as good (for paint prepping) exists, is far less dangerous and is possibly cheaper. In your eyes you may be a hero "I use much more carcenogenic liquids" but when technology offers a safer alternative, what's to lose???? I have worked in agriculture all my adult life - I have heard your sentiment expressed, regarding all sorts of chemicals, so many many times. The bottom line - there is no such thing as a safe chemical. PPE is a last resort, a very long way behind using a safer product, which should still be used with PPE.

Yep! That's how I purchase it in 5L containers from my local wholesale cleaning products supplier. The stuff you get from Bunnings etc is in very small volume and cost a fortune. I usually decant into a spray bottle - great for all sorts of cleaning/degreasing jobs. I suspect it "conditions" a painted surface, such that overpainting takes/key in better

Thinnes will do the job (may containe Acetone). Unfortunatly it's nasty stuff (may also be more costly) compared with Isopropanol. I learnt about Isopropanol, as a pre paint surface cleaner, when I did the refurb of my Zephyr, using a US certified aircraft paint system - it was their go to prep product. Have used it ever since for all sorts of cleaning jobs.

All of the above, depending on the situation. It almost seems like you are searching /looking for a rule. The student MUST be taught to respond to the dynamics of the situation in/approaching/departing the circuit and communicate accordingly. I operate on the basis that at least two calls are required, even if there does not appear to be any other aircraft in the vicinity.

A possibly less nasty substitute, for Acetone, is Isopropanol (100%) - cost effective purchase from wholesale industrial/domestic cleaning suppliers

My personal theory & practice; I believe that, when in flight, human eyesight is poorly adapted to spotting other aircraft, ergo any help that I can get/offer will assist in making that so important visual connection when in congested (circuit) airspace. I also believe in air courtesy - making it easier for other pilots to know where I am & what I intend.

The carb vents(s), two into one, with a perforated brass tube at the end, was in place when I purchased it way back about 15 years ago now. I assume that it was ATEC Zephyr installation and left it as is (replaced tubing at 5 year interval) System worked perfectly for me. Engine ran like a sewing machine, never a problem. At 100 knots, 5200rpm, Fiti prop set for 5200 rpm static, with full fuel and just me flying delivered a tad over 12L/hr (including TO/Climb/landing). "... engine mount threads were very short....." Have no idea what this means - please expand.

"That DeSoto reference would be in relation to a colour code" Wrong! Its a two pack, very thin primer - dull olive green. Consider asking a question, rather than making a incorrect statement.😈

Great to see my old Zephyr back in the air 😊

Seems to me that outback (low rainfall areas) strips are not usually made to accommodate significant rainfall. I think is this probably a reasonable strategy, as to make them all-weather would be a major cost that cannot be justified for an infrequently used asset. Where there is a contact name/phone number, it is the pilot's responsibility to phone ahead for a strip condition report. Philster - I would like to hear a lot more about your trip across Australia (it's on my bucket list). What was your rout & why? Where did you land? Fuel? Bed? Food? etc

My Sonex Legacy has been undercoated/treated, during the fabrication/pre assembly stage, using the following spayed on products: External: DeSoto 51X349 Internal: Alodined,/ BMS10-11 (I was not involved in the above stage/process) Once completed, the airframe was painted with a high pigment automotive/industrial paint. High pigment so that complete coverage could be archived with a single coating.

Damien - There is a huge range of voltage regulator and opinions on what is best/most cost effective. Do a google search - Everything from ride on mower & motorcycle units, to Rotax OM (the most costly by far). Everyone swears by their particular choice, so very hard to get an unbiased recommendation. Much will depend on your budget and willingness to try something other than OM. The following, non Rotax, alternatives have some enthusiastic users and detractors: Silent Hektik Ducati John Deere AVC1 Carr 5115 Advanced Power Whatever you get, make sure it is mounted in a well vented area - VR's have cooling fins to dissipate heat, so need some airflow for long service life. RFGuy or one of the other electronics experts, on this Forum, are possibly your best bet for advice.

Now that I have my Sonex teething problems sorted (at least for the time being) I am keen to do a series of day flights exploring NSW (could be persuaded to get into Qld/Vic, passport will need updating). My departure point is The Oaks, NSW Suggestions welcome.

Not going to happen - Rotax Maintenance Manuals are THE WORD and THE WORD IS GOOD thus saith a Rotax owner, who doesn't want to risk damage to his 912ULS, by experimenting on leaving off a few cents worth of conductive paste. In the unlikly event, that you are correct and there is no benefit, neither can there be any harm, in applying the past as specified.😈

Keep us posted on your plans, dates, etc

If you purchase your Rotax plugs B from Floods, you have the option, for a small fee, to have the threads "treated" with the appropriate paste - I have never asked what brand but assume they would use Wacker P 12. This does not mean that all patrons of B Flood, go to the added small expense, however my money is that most will and those that don't will apply their own.

Hi IBob, Speculation: Would not a made to measure rectangular steel plate, say 4-5 mm thick, spread the load better than a stack of washers?? You could also consider hard rubber (or metal) spacer, back bolt shaft, between fuselage & retaining plate, to limit the pivoting action.
