    Guess The Airstrip

    in AUS/NZ General Discussion

    Posted

    G'day all, just going a little sideways here for a second...

    Found a new airstrip register site, and wonder if anybody (in Tassie) knows the owner?

    https://landingareas.com.au/

    It looks pretty, but as soon as people see you have to log in to use it, most will just move on.

    Owner should at least have a contact detail (email) so people can update his info, and figure out how to register to log in...🤔:blink:

    Totally agree with facthunter there,if you can fly a corby you can fly a drifter

    I agree with this statement BUT, not the other way around.

    The Drifter is one of the most benign tail draggers out there, it's a good stepping stone into tail wheel, but being able to fly one wouldn't guarantee being able to fly something like a Skyfox. Never flown a tailwheel Corby, so don't know what they are like on the ground?

    'Welcome to OneSky™ Australia, where we want everyone to be included.'

    To be included in 'OneSky'™ will cost you about ten thousand dollars per aircraft for initial installation,

    An annual fee will be paid to 'OneSky'™ to register each of your required devices,

    You will have to comply with all 'OneSky'™ decision changes as they come,

    If you wish to leave your circuit area you will need a flightplan lodged with 'OneSky'™,

    With 'OneSky'™, you will be safely integrated with;

    •Military aircraft,

    •International Airlines,

    •Civilian Airlines,

    •Regional freight aircraft,

    •Military IFR traffic,

    •Civilian IFR traffic,

    •Private IFR trafic,

    •Military UAVs,

    •Civilian UAVs,

    note: If you cannot comply with the integration of 'OneSky'™, you probably shouldn't be flying (it is for rich people after all).

     

    WE hope you enjoy your 'OneSky'™ experience.♥

    Proposed lowering of Class E airspace.

    I'm surprised there's not a raging debate going on here?

    I guess that since ultralights all died off, we;re all happily flying around in our $200K sport planes, with dual coms, dual nav, ADSB transponders , FLARM (for good measure) and Avmaps/Ozrunways flight following.

    Who needs to bother looking outside anymore...?

    Glider enters cloud

    Yes, convex, or as we used to say, 'up in the bowl' or bell.

    As someone commented, you could thermal tightly up into the bowl, then punch out through the side, and provided it was a singular cumulus cloud, you would be out in a few seconds.

    REALLY not a good idea in a street 😱

    As for instruments, most Blaniks (and IS-28's) came fitted with a battery powered 2 1/4" turn coordinators (Bat and Ball), that seemed to work fairly well. 🤔

    But yeah, wouldn't want to be ridge soaring with all that cumulogranite around.

    We're open to ideas to remove plastic from alloy, but often the problem is UV degradation caused, believe it or not, by fluro lighting, which make the plastic brittle and can no longer be peeled off as it just breaks into little pieces.

    •Heatguns work to a fashion, but a very narrow temperature is needed between having no effect, to becoming a (hot) sticky goo.

    •Thinners and metho do absolutely nothing, except maybe dry the plastic and make it harder.

    •Turps will attack the adhesive and will sort of work on very old plastic as it becomes somewhat permeable, but if only 'partially' baked, will only attack the edges.

    Going to paint strippers, petrol and the like are not guaranteed, and make an even worse mess sometimes.

    I think I remember having some success with 'gunwash' once upon a time...?

     

    Meanwhile we're dealing with lots of little fiddly bits;

    1/2 Volkswagon alternative

    in Engines and Props

    Posted

    Not really sure this is an 'alternative' to a half VW?

    Even if you cut the biggest VW in half (2400cc), you end up with a 1200cc chaff cutter, and when you consider that half an 0-200 is a 1600cc, why not just use a 1600cc VW?

    Probably around the same weight, would run smoother and use about the same fuel.

    That said, for similar weight again, you could use a 1200cc Rotax (912UL) and get 80hp with a more effective prop and only two thirds the fuel burn.

    If you only want 56hp, I'd probably go up to 65hp and use a Rotax582 for just under $9k, new in the box.

    Have just stumbled across this project, and it is eye-opening, although to my view, not altogether in a positive note.

    While I admit that, yes it will fly and it will be fast, when you look behind the hype and the droolable goodies, there are some questionable 'advances' being utilised in the design and manufacture of this project.

    I've only watched four or five of the videos, but each one set off the odd alarm bell, more in the cost and engineering concepts, rather than the build quality or production rate, which are inspiring.

    Have a look through the youtube channel; 

    https://www.youtube.com/c/DarkAeroInc/videos

    The one that stuck in my mind initially was the CNC'd nose leg, which gave me 'engineering overkill' vibes to the max, for something that was still only a simple unit and possibly subject to failure (think; the joining lugs cracking off), despite the beautiful workmanship.

    Another was the home made carbon/honeycomb board, which has great strength in bending resistance, which is then used to make ribs and stringers, that take shear loads.

    .

    I was watching these a 1:00am this morning and must now get back to my own projects, but was just interested to hear other's thoughts...

    Rotax 912 pricing

    I don't see the point of a direct copy of the Rotax.

    Tend to agree. Considering the age of the 912 I would assume there has beed room for improvement over the years...

    My personal thought is that Rotax made a mistake by not having a common crossflow head, which would have;

    a. Allowed one common head for the whole engine,

    b. Allowed the eventual creation of a six cylinder (worked for Jabiru).

    Obviously in todays market, the engine should be fuel injected as standard with a single throttle body. The new longer gearbox housing was a long time coming as well.

    Maybe a choice of gear ratios as well?

    Anyone know if Rotax still make 4:1 C or E boxes?

    Not sure which photos/movies Planet47 wanted to put up, but we have managed to get this far...

    This is the first stage of folding the wings; Unpin rear spar fitting, roll wings forward (pictured), then swing wings back along fuse.

    The cutout inboard on the leading edge is where the tanks will go, and the open skin on top is just where we're accessing the spar fittings as it goes together.

    Can't actually swing the wings back yet as we've totally run out of room.
