    Having Rotax deny sales to Turkey, or any other country that could be similarly labeled is a moot point as said manufacturers will simply go to the Chinese clone company and buy their Rotax's from them.

    Which is weird because that thread is General Aviation, while the discussion is obviously a Governing Bodies topic?

    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...? *Please refer to this thread;* Oops, removes foot from mouth and moves on...

    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;

    Big clunky magnetos with two spare poles...🤔 I wonder if you could swap all the electronic ignition off a 582, and fit to the back of (any) half flat motors? Not only a smaller more compact magneto system, but you get an alternator as well 😏

    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...

    According to the rumour mill, Jabiru made their own engine after the Israelis' bought up an entire years worth of KFM's production. This would suggest that there could be KFM spares to be sourced in Israel?
  13. pylon500
    Not everybody has facebook, but by the sounds of it, you were looking at this one...
  14. pylon500
    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?

    If you're feeling brave, maybe you want to have a go at this lot... https://airkmotors.com/?lang=en#moteurs

    Not sure which photos/movies Planet47 wanted to put up, but we have managed to get this far... (Didn't realise I shook this one till I blew it up) 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.

    Been there, done that. Safely landed a hanglider in a tree short of the planned paddock. Fell out of the tree and broke my wrist.

    Can't remember if it was Chuck Yeager or Bob Hoover said, "Find the softest thing around, and crash into that."

    Don't the RV-12's fit in? (update) Looks like a Zenith.
  20. pylon500
    I think a lot of the improvement comes from the fact that the 912is doesn't have carbi's! It's fuel injected. Not to highlight ancient technology, but with good EGT's and mixture control, the old Lycosuarus's probably doesn't do too bad, but remember, your driving an engine more than twice the size of a Rotax, for the same power.

    Couldn't really tell you actual weights, but the 233 is a lightweight version of the 235, not sure what they did, but I think they were aiming it at the LSA market.
  22. pylon500
    Don't know a whole lot about Lycomings, but I suspect the power output is just related to what rpm you want to operate it at? Been a few years since I flew this, but I thought take off was around 2700?
  23. pylon500
    Just a s a side note for anyone interested, there is an extensively modified (but finished and flying) J200 possibly coming up for sale. Mods include; Tailwheel conversion. Lycoming 0-233 installed. Original ignition replaced with full electronic. Auto pilot. Enlarged tailplane. I've got a few hours in this thing, and it's a beast! Can't remember the cruise speed, but in excess of 100kts (like 120Kts?) Owner is getting ready to fully retire with back problems, which make getting in and out, as well as sitting for long periods of time, a bit painful.

    ? Sorry, a little confusion there... The above photo is a view out of the Wasp, the Hornet has a centre vertical brace in the windscreen, and as can be seen, this is a side by side aircraft. Quick bit of (unofficial) history. Ole's first product was the Hornet STOL, which is the highwing, two seat side by side taildragger, and still in production. He then made the Wasp which is a mid wing, two seat side by side tricycle gear, notable for it's forward swept wings to get the pilots in front of the main spar for visibility. (Discontinued) His next machine was the Bushman, which was an oversized tandem Hornet (two built) which led to the Hornet 'Cub' which is a similarly sized tandem version of the Hornet, and both are still in orderable. The latest variation has been the Flamingo, which was designed as a Super Slow machine, used to tow hang gliders. It achieved most of the flight goals, but couldn't compete with the price of the basic dacron and tube Moyes Dragonfly. Pictures of these machines can be seen on his website; http://www.aircraftkits.com.au/

    Anyone else see my attachments? I just get the oops message... As for J3300 vs R912s weights, the totally installed and running weight of the 912s is probably just a little higher than the 3300 after you add two radiators, coolant and an oil tank. Obviously a 914 would be heavier again. I know there's been a few '100' series Jabs with 912's fitted, and balance was a problem, but the length of a J230 hardly notices it. Going to repost the attachments just in case... (I think last time I must have hit Preview instead of Post)
