    PS well done spotting them proud rivets! And...I actually wrote to ICP more recently about the Savannah manual.....endeavouring to point out that translation is best done by native speakers (in fact, prior to the interweb, professional translators translated only INTO their native language). To which I received a polite reply from the technical manager........in broken English. Well..........I tried.........(

    sfG for my Sav build, I found it useful to put the parts listing (with it's exploded diagrams) into a separate manual, so that I could have both that and the build manual open at the same time. I also benefited hugely from build pics posted by others on this site....so much so at times that I also had an old laptop on the bench where I could look at the pics. Also in the first part of the build there was another builder in the area: initially I was ahead of him and he would ask me about stuff, then I took a break and he got ahead so I was calling him. I also messaged Mark Kyle on occasions, and he was always helpful. And finally I would bounce stuff off the then Australian agent, who was hugely knowledgeable. But I didn't bother him unless all else failed. All of which is to say I think it is far harder if you are working in isolation. And much easier (and less error prone) if you are in contact with other builders.........

    The Savannah manual calls for countersunk A4 rivets fitted flush there.

    Hopefully dey got a natif English speaker to translate Die Ventura Book.........)

    With the riveting 'beads', suggest you make several as they tend to fall off and roll under the bench when you pull the rivet. And I think steel (mine were just MS reinforcing rod) would be better than aluminium, which does not slide freely. In retrospect a bit of soap on the stem would probably help when doing this.....though it's not something I tried.

    You and every other builder, ever, sfG..........) BTW a few rivets will probably be in tight corners. Looking at what others had done, I filed as much as possible off the top of my rivet gun to make it less bulky there. And you can also pull rivets without having the gun straight: I drilled a rivet stem sized hole down the centre of some 1/4" steel rod, then cut it off into individual 'beads'. By filing an angle onto one end of the bead (which you then thread onto the rivet stem), you can pull a rivet flush with the gun at an angle. There are obvious limits to this and sometimes the stem breaks high, rather than in the rivet body, but that is easily cleaned up.

    sfG, as discussed elsewhere here, the corrosion proofing of joins is very important. I primed everything, but initially used the black stuff and brushing or speed brushing did not work well at all, giving me uneven cover and a lot of black stuff pushed through the rivet holes. Were I to build again, I would definitely invest in the Paint Buddy. While they are not readily available in NZ or Australia, I would see the cost and inconvenience of sourcing from elsewhere as very minor in the context of the build, both in terms of ease and economy of use and making a proper job of it. If it is anything like the Savannah, you don't need many tools, but it makes a big difference to speed and quality of build if those tools are well matched to the job.

    Looking at the height above ground: there's two guys dodged the final bullet.........

    Stick with it Danny: Our local field has town on one side, circuits for the main strip are always away from town, so LH or or RH depending on wind direction. I trained here, this is just how it is and I never really developed any preference. So I suspect a good part of it is what you are habituated to. I fly a Savannah too, and a nice thing about the XL or S is that you can dip the starboard wing and have a look through the roof before committing to a starboard turn.

    Yep, there was a guy used to do it in a Cub in NZ in the 70s. Dressed as a little old lady, would hobble out on a stick. Started his routine with a great deal of careering round the field before actually taking off. Grass fields, so he didn't drag the tips, but a pretty good show for all that.....)

    You're right Marty. And gearboxes.
  12. IBob
    I wonder what the drive mechanism is to those props???
  13. IBob
    Looks like the one on the right is POC? Then the LH one they've ditched the lower struts and gone from pusher to tractor.....
  14. IBob
    Lancair, I think.

    It looks as though they had a fatal on day one............(

    I had the Aeroflot experience in the 80s, Vladivostok to Petropavlovsk. Midwinter at night, looking out over miles of snow with not a single light, thinking we're in trouble if the music stops. We had taxiied out past a whole long row of identical Tupolevs, perhaps the result of Soviet era overproduction? Some of them actually had canvas showing through their tyres. On our flight there was something wrong with the toilet seal, they had a curtain across the toilet bay which blew back at about 30degrees for the entire flight, to the accompaniment of the roar of escaping air. And, while many Russian women are beautiful, the two hostesses on an otherwise all male flight were grim individuals built like heavyweight wrestlers. They strode down the centre aisle without ever turning sideways, and anyone leaving an arm or a shoulder out got slammed with a very big hip. The impression was that they were there to keep order, there were certainly no drinks or food served. We came out about 3months later, unshaven, half crazy and full of vodka. So I don't much recall the flight back.............(

    I visited Dunkeswell in the late '70s. The gliding club there were towing gliders off with old Jaguars (Mk8?) from the wreckers. They took the boot lids off and threw them away so they could coil the tow line and toss it in the boot after each tow. And when the Jag eventually blew up, they just went to the wreckers and got another one......cost about 10pounds, as I recall, as nobody wanted them.

    Yep, a huge number of boats and ships lost.....including the entire British Channel Fleet. I read a harrowing account of vessels of all size, trying to anchor off the East of England rather than get wrecked in the surf.....all in sight of each other and some with their anchors dragging, cutting down their masts and rigging and still being dragged. Once they hit the surf they were gone.........you can't float in surf but you can't breathe it either......(

    Okay. total thread drift......but take a look at the Great Storm of 1703: https://en.wikipedia.org/wiki/Great_storm_of_1703

    Rotax springs....

    Let's see...............how can we maximise drag here.........while making sure everyone on board gets to fully appreciate the roar of the engines..........hmmmmm

    You said the problem 'followed the EGT' when you moved the probe. Did you mean the problem remained at the same pipe.....or it moved when you moved the probe? Some thoughts: 1.The EGT probes are a standard K type thermocouple, two dissimilar metals welded together at the tip, produce a small voltage when heated. So not hard to check with a multimeter set to mV. There will be lookup tables for temp vs voltage. 2. It is my understanding that those same metals must be must be used all the way back to the Dynon. Red and yellow I think they are. Asking the stupid question: you don't have a join where the red/yellow have been crossed up? 3. The exhaust gases will not pass down the pipe in a uniform manner, especially close to the heads. Are the probes installed as recommended, and fully into the pipe? Could there a be leak there resulting in a hot spot? 4. If all that checks out, it does seem likely that it is associated with the remodelled pipe and/or anything that was disturbed at that time.

    I was chase crew in Scotland where 2 people jumped (individually) leaving only the pilot. Evidently he put the balloon in a hard sink before dropping anyone, as he wasn't sure how the balloon would behave. And yes, it tended to go back up, but it did nothing suddenly or violently, he said another time he would just keep climbing. Having said that......the pilot is the captain and what he says goes.......absolutely. Mr 2000jumps in the clip is a plonker........

    Something interesting going on with the upper outer leading edges there?
