here are some examples I found on the net of oil filter crushing,
both are from Rotax powered sea-doo's (the ones I physically witnessed were in this application)
easy to see as this is a cartridge type instead of a spin on, where it would be hidden by the outer case.

still see the same damage with spin on's as the inside wall collapses - but harder to photograph

this is the oil system - risking major engine damage if anything goes wrong. for what a $10 saving?

will never understand why people cheap out in this area

Interestingly there are no cross references through the regular options, I used as an automotive parts interpreter.

The bypass valves and the micron rating on the filter medium make a big difference.
seen a few engines come in with a collapsed oil filter from the pressure - used to have some pictures on an old hard drive - very impressive to see the crush damage.
A workshop I used to work for had a motor destroyed by a reputable aftermarket filters with the wrong flow control valve- the filter company covered the repair from memory.

had to be careful with the Harley-Davidson filters.
the old evo filters and the twin-cam filter were identical looking. but they had different Micron levels in the filter medium (Evo was 10 micron, TC was 5 micron).
could use the new twin cam filter on an older Evo, but couldn't go the other way from memory.

should see the price of filters in the hydraulics industry.
blew my mind the first time I saw a $300 filter.... and it wasn't that much bigger then a van/truck filter.
 

$36.50 is a good price,

last I checked my Ducati filter was about $45.

cant compare to automotive the qty is different.
same engines used across multiple models, and same filter used across multiple engines - manufacturing in the millions.
completely different economy of scale.
 

Im assuming CASA has the same brief as the previous ministers gave.

There's a metric thread called ISO if I remember correctly, used on Japanese Motorcycles. The Imp and US cycle threads. Whit and NF form and 26/20 tpi and 24/20 tpi respectively. That gives you the fine and coarse threads for various purposes. You'll also come across BSF whit  on Brit  bikes.and  NF  UNC on US bikes . Nev

Japanese bikes use JIS

Japanese industry standard.

just slightly different - most notably in the smaller screws. best example is the front brake master cylinder.
which is why they almost always strip out when people do their own services - without the JIS screwdrivers.

Yeah, I just remember an interview with a sea stallion pilot,

where he was going through how maintenance hungry they were. and all the hydraulic issues.

very much a case of if there was no hydraulics leaks, then the system was empty.

additional point, there has been a lot of talk about it being a complicated aircraft....

but lets not forget that the alternatives are similarly complex. with their own automated folding systems

yeah, the article I posted earlier talked about the Marines loosing 6 sea-knight helicopters from 2001-20012

I'm not the only one questioning it. Just WHAT is a rotorcraft? A helicopter is rotary wing with lots of control. Just because clowns design such things doesn't mean pilots can fly them. History is filled with dud aeroplanes. Ones that didn't meet design Parameters or expectations.

A rotorcraft or rotary-wing aircraft is a heavier-than-air aircraft with rotary wings or rotor blades, which generate lift by rotating around a vertical mast. Several rotor blades mounted on a single mast are referred to as a rotor. The International Civil Aviation Organization (ICAO) defines a rotorcraft as "supported in flight by the reactions of the air on one or more rotors"

hmm it does bring a good question about what makes an engine an engine by definition.

is it the crankcase or the crank shaft?

and how's that work for stackable options like a Rotary. that can have theoretically as many crank cases bolted together as wanted,
its limiting factor is creating a crankshaft that takes the forces.

Once again, its not new technology.

was played with in the 50/60's

Believe it or not the MV-22 Osprey is the safest rotorcraft the Maines operate

https://www.popularmechanics.com/military/a7663/how-safe-is-the-mv-22-osprey-8036684/
. 
and find me a western fighter built since the 70's that didn't have a computer managed flight system.

I dare say its easier to control then a Harrier, or the Lunar lander.

its the first generation and has had its teething problems out in the public.

just like the F35. its a fairly mature design now and they have the second generation starting to be built with the V-280 Valor

WTF does blockchain have to do with aircraft?
its an record/accountancy thing.
 

and AI these days has basically just become the new buzz term for machine controlled or learning.

these same guys would say the the F16 and F117 is AI controlled. 

what engine was it using,

they word is "with standard Rotax ULS 100hp"

anything can be a world record if you put enough details on it.

The numbers indicate which aircraft carrier it is. eg.: USS Gerald Ford is No. 78.  No. 65 is the USS Enterprise.

Don't land on the wrong carrier

Its ceremony for the "shooters"

to launch their boots at the end of a tour

And a second hand A32 Vixxen is $172k on plane sales....

We all want scrappy's wing. but I doubt anyone wants to pay the cost for manufacturing and development.

the Jabiru is a cheap basic aircraft. plenty of other faster and slower flying options available.
no point chasing after it - if its going to take away from its primary selling advantage.

still has the supply of parts and services.
which probably suits the kit supply of light aircraft, may have the facilities still to do the factory built - or leave as is.

with Mahindra's component manufacturing could take the engine build/development back to India and work on bringing prices down.
to provide an entry into the light aircraft market. at the moment they have been playing mostly with the bigger commercial stuff

How many aircraft manufacturers are in Victoria?

my guess is GippsAero
who are apparently backed by Mahindra

i don't know if the low stall speeds are all they are cracked up to be.
remember swapping from the Jabiru to the Vixen.
sure in theory the Vixen had a lower stall speed and better short field - but get the airspeed wrong and it floated down the whole runway,
get it wrong in the Jab, she would still slow so often rescuable.

and the biggest hurdle of all. the noise cancelling headset.
how many would rather have a good fitting noise cancelling headset - over an in-built coms system that lets in noise.

any aircraft helmet I believe will always be inherently flawed because of the priority for communication and comfort.
every pilots helmet I view on google has the ear cups off a headset grafted into it. that's a lot of foam carved out. often the shell bulges to accommodate these cups.
as opposed to a motorcycle headset which uses 3mm speakers slid into a form fitting liner.
 

yeah, 
and then we get into the rotational forces.
where the Mips system comes into play.

its the yellow part on this helmet. lets the inner and outer layer slip slightly to redirect the rotational forces away from the head in an angular impact.

There is an absolute ton of research and development in modern helmets.

(Also keep in mind that is a bicycle helmet, look at the coverage and thickness of the foam compared to the ultralight helmet posted earlier....
apparently its not just engines and airframes, the helmets stuck in the 70's too)
 

found a paragliding helmet to compare with. note that there is nothing but liner around the side of the head
