While RAAus instructing in Sydney, I had a young guy come out that was thinking of joining the RAAF as a pilot and wanted a bit of a 'heads up' on what to expect. He couldn't afford to do much with GA so gave ultralights a go. Being ex RAAF (only ground work) I had an idea of what was coming, so after some theory we headed off in the Lightwing and I gave him a serious TIF. He understood what was going on and enjoyed it enough to come back and really put in some hours. I cant remember if he went solo before going up to Tamworth for the tryout, but off he went. The training and evaluation done at Tamworth (then) was around 14 hours in CT-4's, and if you picked up quick enough, you could get an hour or so in a Cap-10 (taildragger) and some aero's. My student did ten hours in the CT-4 and was the only one to get another four hours in the Cap-10 But alas youth, although he came back to the club, continued to full certification in the Lightwing and our Foxbat, he decided there was more money in computers and went off to Uni.....

Yak 50 Engine failure and forced landing video.
pylon500 replied to Ultralights's topic in AUS/NZ General Discussion
Not to appear to 'kick him while down', but I saw a lot of things that made me wonder a bit; •Flying at around 2500 feet he loses oil pressure, but according to the time frame doesn't land for nearly another eight minutes? •At one stage he actually climbs? •He starts off near a small town with reasonable fields around it, but heads off around a range of hills? •Although the captions mention an oil film on the windscreen (not really noticed), he then degrades his glide performance by opening his canopy? •The helmet cam appeared to be well orientated to where ever he looked, as such, he spent a lot of time in the last minute looking at a large field which he then glided over the full length of before hitting the wall into the next (and smaller) field? True enough, he walked away from it, and you usually only get one go at these things. But the engine was probably totally destroyed before he got to the ground, he wrecked the aircraft on landing, he then casually climbed out and walked away leaving all the electrics on. Sorry, but I don't always credit survivors as hero's, just lucky. Arthur. (Puts on fireproof suit) :Annie: -
Listening to the video a couple of times, and allowing for sound/distance time, it seems more likely the prop disintegrated (the initial bang) followed by the engine winding up to around probably 10,000rpm whereupon it also disintegrated (my opinion). The story here at the EAA website with some good photo's of the engine. Arthur.

While the engine may be similar in dimension to the Jab, it's hard to believe that it is also close to the same weight? Even if the basic engine is similar, you need to add the weight of the cooling system when doing your CofG calcs.... I'm pretty sure Gary will advise on changing the firewall position to suit the new weight, and there's plenty of nose to shorten on the Cougar. Arthur.

G'Day Maj, you're the first person to question the C177 taildragger (which to the best of my knowledge, doesn't exist :ah_oh:), it's just me playing with photoshop again. By the way, a C188 is an AgWagon....;) Doin' well, busy flying and fixin' planes.... Arthur.

OK, Here's another,

OK, The coloured fish I refer to would be the RED HERRING! If you Google B-17 Single Engine (can't get a URL link to take?), there is much discussion if the aircraft ever existed in the above format, most tend to believe it is photoshopped. Has there ever been a thread here before showcasing aircraft photoshop? Arthur.

Have a go at this one, there's something about a certain coloured fish to this one?i_dunno

A 912s powered Sierra was built and sent to New Zealand, no idea what happened after that. The instal was a bit more complicated than the Jab, but managed to fit.
-
Actually I think a better question is why does the 3.300lt Jab run on only one carb when Rotax thinks it better for their 1.200lt engine to run on two? :csm:

You don't even have to be on a council airport to have problems. My private property backs onto an airport and my DA to build a hangar was approved, but not as a rural shed (like most of my neighbors') but as a commercial warehouse, complete with all the regulations that go with it Guess you shouldn't tell councils anything about what you might do in your shed. I'm still working on this problem so I can extend.. Arthur.

I'm running Safari on a Mac, and do the following; 1/ Open the download page (under 'window') 2/ Open the Activity page (under 'window') 3/ Start the webpage-video you want 4/ Looking in the Activity page, find the address line that is in MB's, not just KB's (should be counting up) 5/ Copy this line and paste in the download window, WHILE IT IS STILL DOWNLOADING!(once it finishes downloading it just becomes an icon). You should end up with a .flv file on your desktop. I've had a look at Firefox, but I can't find an equivalent to 'Activity'? I looked in Tools-Page Info-Media(button) then tried to Save As.., but it didn't work ::(: Once the file is downloaded, you may need to change it from a .flv (a flash video) to a .wmv (a windows media video), not sure what happens if you try to save it as a .mpg file? Arthur.

You will find that it is a machine called an 'AIR-CAM', have a look HERE. Arthur.

As long as we're not called REKKERS

Thanks for the compliment I cant see why people go to the trouble of building in composite, and make a square box :raise_eyebrow: I was almost going to carve an elliptical wing and tail, but the swept shape looks faster Sorry about the slow replies, I don't visit as often as I should. Arthur.

Good info, thanks :thumb_up: Arthur.

There is a few of us about, check my links... Arthur.

While the Sapphire is probably easier to land than a Lightwing, you need to be aware of the very light controls in the Sapphire, and the possibility of over-controlling. If it's a stock Sapphire, hold the controls gently, but NEVER let go of the stick. An anti-servo trim system is a good mod for a Sapphire. Arthur.

It's not my plane and used to be VH registered. It also comes with a fuel card I guess that's my answer, it did start better after the plugs were cleaned. Doing more flying lately, will have to clean more regularly. Arthur.
-
OK, a quick one then. I'm running an 80hp 912 on 100LL, with good temps indicated, but have recently been having some starting problems. Unsure if I'm flooding or still dry, I've removed plugs to inspect, and found them to have a noticeable yellow colour? Didn't think to photograph. Is this typical of 100LL?
-
Watched a couple of the early test hops, good STOL performance, but was having trouble with a dodgy motor. This is being replaced with a small Lycoming (or Continental, I'm not sure) and is nearly ready to fly again. Olle is pretty busy at the moment, but will continue testing soon. Having walked around the Bushman, it is actually a bit bigger than a Hornet, great visibility from the cockpit and plenty of hauling space. Arthur.

Flying with sunnies. Which kind?
pylon500 replied to flying dog's topic in AUS/NZ General Discussion
As an aside to polarisation, Tint colour can also be important when choosing sun glasses. Typically, common sunglasses tend towards greys, blues and green tints, all of which will just cut down on the amount of light as well as colour being observed. ie, you loose vision and detail. I'm no optometrist, but I find that brown tint lenses cut down light intensity, but tend to enhance colour definition. Back in my Hang-Gliding days a pink coloured tint was all the rage as it was supposed to show dust in the air to signify the presence of a thermal. This may have been true but I found they just made everything brighter and made your eyes feel weird for about ten minutes till you got used to them. Then you felt weird again when you took them off! I just use brown sunnies with a graduated tint and try to find ones with thin arms to fit into headsets. Arthur. -
Now do it in a Tail dragger!

G'Day Ian. That yellow BD-5 is now at Canberra, but I don't think it's ever flown?i_dunno An earlier AUF member build one up as a 'BD-5J' (jet powered) and got the engine to run, but then sold it to the US. I know of 3 finished airframes that were in WA, two that actually flew, one of which suffered an engine failure at takeoff and bellied in, catching fire and injuring the pilot. Some good footage on from Serpentine in WA prior to the crash. In the 70's, the BD-5 was my favourite aircraft and eventually I managed to get most of a kit, a year later I got most of another kit, and a set of plans. The BD-5 is too hot to fit into the ultralight category (even the long wing), and I have determined there are numerous little problems associated with the structure (not altogether fatal, but could have been done better) Some time in the future when I'm really retired, I'm planning on reconfiguring the kits into something that will fit the 19-XXXX category, but that's a way off yet.... Arthur.

I recently downloaded the assembly drawings for the Lazair from this Site. A 5 Mb PDF. Many others at the Parent Site. Arthur.
