Yes the carbon infuses into the metal with the heat of operation and makes the alloy brittle. Nev

Hi Bluey,

Your best bet is to get a replacement from Airborne.

I don't think it would cost you much more than having it welded.

Invariably if you have welded the stainless, after a short time you will find another crack very near to the weld

What are the thoughts on pilots not reporting accidents/incidents ?

Sorry, but I just have to disagree with this point. It's what started this whole thread and the effort to move the antennas around. Here's why.The most common antenna supplied with Airborne trikes is a counterpoise type. Even though the counterpoise does not radiate signal, it's electrical characteristics are tuned for the antenna. If the antenna is mounted on the kingpost with the active end pointing down as supplied by Airborne, the kingpost loads and shadows the antenna radiation pattern. This also increases the VSWR which is not good for the transmitter outputs and could even be fatal. If the antenna is turned up the other way, with the active end pointing up, then the counterpoise lies alongside the kingpost. This changes the effective RF characteristics of the counterpoise and consequently the balance of the antenna. Again, not an ideal situation.

 

I don't really know how the V rabbit type antennas work, so the top of the kingpost may be ideal for them, but it's defininately a no-go zone for the counterpoise types. Nor is it a good place for groundplane type antennas.

 

Like Dieselten, my RF knowledge is very rusty (USAF C.1970's; NASA tracking station C. 1980's) But the good people at Mobile One (who manufacture the antennas supplied by Airborne) confirm that the kingpost mount is a no-no.

 

BTW, This post wasn't meant to be a flame, and I hope it didn't come across like that.

The Vee Rabbit is designed to mount on the king post but below the peak. That way it does not get damaged when moving in and out the hangar. I fly an SST and I have the aerial mounted horizontally on a short keel extension so that I can get it in and out of my low hangar without causing damage. I have an extremely clear transmission and reception well over 100KMs. (do we need better in a trike?) This with a hand held Vertex I have yet to have people say I am unreadable in normal circumstances in fact people remark how clear my transmissions are:clap:

Hi everybody,Newbie recreational student pilot who has just started training - hoping to learn a lot on these forums

After all this rain in the Sydney area, dies anyone know of the condition of YKAT, Katoomba, and the Somersby airstrip?

You just need to know how to handle the turbulance at the airfield and remember it is a one way strip :big_grin:

Kev what you need to do is make a short keel extension for the wing and mount the aerial horizontaly, then all that is required is to pull out a pin and disconect the aerial. You should be able to do that in under 1 minute and yes it does work just as well in the horizontal:clap:

Can't you try washing your trikes instead of selling them! :) One day I will actually get back to Somersby and maybe even put my plane back together!Adam.

Maybe leave a photo so we can recognise you

And then we have the hang gliders and para gliders on CB radios with no height restriction :confused:

Hi David,

It is possible to adjust the brightness level.

If I remember correctly I have the info at the airfield.

I had a major problem with the instruments failing and SkyDat accused me of being difficult and not wanting there product.

I will have a look tomorrow.

Thanks David,I wasn`t aware that there was any difference in,standard, jet size in the 582 and if,as Andy has said,the pump delivers 100:1 at low revs,then there would be even less oil,at these revs than premixed,regardless of jet size.

Frank.

 

( If It Ain`t Broke,Don`t Fix It.)

In 4 trikes never had an engine failure and I certainly would only use and recomend auto lube

Dennis,I have a question, do you use the solid tip spark plugs or the ones with a srew on tip?

 

The reason I ask this is the screw on tip plugs will wear the inner of your caps out.

 

Always use the solid tip spark plugs.

 

On your question I dont think it should make too much difference with these plug caps from Wade Air as you would think they should know what they are doing will parts for different types of aircraft @ engines.

 

I guess you could get the same type as you have originallyfrom Bert Floods at about $30+ each cap, i paid $27 for each cap about 4 years ago for my 582 so i really would hate to see the cost of them now.

 

But as they say there is no price on safety in aviation so if your uncomfortable with what you got change them out.

 

Cheers

The last SST I bought from Airborne had the screw top plugs.

I personally have never had a problem using them on two 582's and four 912's (maybe I don't keep them long enough )

Hi Gordon,

Welcome from The Central Coast!

Mc Guyver:I looked back through this thread to see if you had posted pics of your setup. It doesn't appear that you have, yet I feel Like I've seen it or something similar. If you haven't posted any pics, how about it? I'd love to see what it looks like, and I'll bet others would too.

Attached are 2 pictures. As can be seen I have a strobe mounted on the bracket as well.

Hi :)blueshed:I am a programmer so I will most likely have to work in the city. Looking at the job sites most java developer jobs are in Sydney so that will be the first place I will start looking for work when my residency permit comes through.What is togo?Mc Guyver:Where do you work? Do you travel to work 1.5 hours every day? I live in Roodepoort now and on the bike it takes me about 40 min into Sandton, with the car it would be 1.5 hours. It would be so cool to be able to climb in my airplane and fly from a small airport to Bankstown and take a 30 min train into the city, but if it is days like these I will need IFR instruments

When the weather is good enough, I work at the airfield (trike instructor)

I live in Terrigal which is about 20 minutes from the airfield.

HiThank you for the info

 

I will start doing research about Camden, crime and those things.

 

Is there a train to Sydney CBD from Camden and how long does it normally take?

Crime in Aus is non existant compared to Gauteng

I am based at Somersby which is about 1.5 hrs train ride North of Sydney.

I have been there around seven years.

No empty hangars at this time but the owners are talking of building more in the next few months. Somersby is a difficult airfield which you have to grow into!

The Central Coast is a magnificent area to fly over.

Excellent bunch of guys and everyone is helpful.

Hi Scott,

I use the Vee Rabbitt aerial which attaches to your kingpost. No need to remove it excepting when de rigging completely.It is fitted below the top of the kingpost so does not get damaged in and out of low hangars.The aerial performance is amazing and has no shadowing problems due to its design. I have fitted mine on a special bracket attached to the wing keel (topless wing)

I have posted this in the classified section:

Airborne XT 912 with SST wing - Classifieds

I have copied from another egroup

Erika Gibson, Beeld

Johannesburg - Two participants in the President's Trophy Air Race in Bela Bela in Limpopo on Saturday died when their plane appeared to break into pieces in the air.

Both wings of the Flamingo two-seater plane "fluttered like feathers" while the fuselage fell straight to the ground, said Tertius Myburgh, who flew right behind the Flamingo in his own plane.

Werner Blignaut, a commercial pilot for Naturelink at Wonderboom Airport in Pretoria, and Cronjé Erasmus, his navigator, who was also a flight instructor at SFT flight school at the Kitty Hawk air field outside Pretoria, died in the accident.

The air race has been held since 1937 and Saturday's accident was the first fatal incident since its inception.

Like confetti

According to Myburgh, Saturday's part of the race was from Rustenburg to Bela Bela and back.

They were flying straight towards the turning point at Bela Bela when he saw only the white of the plane's wings "unfold".

"It looked like feathers floating around and afterwards some of the stuff that the plane was made of, blew through the air like confetti.

"I said to my co-pilot: 'Look, that plane is breaking up.' But it was so unreal that I wondered if it hadn't perhaps been a whirlwind.

"The next moment we were above the turning point and no one said anything over the radio. But right after, the message did come through and then I knew that I hadn't imagined it."

Mechanical problem

Chris Briers, who had been on standby with his helicopter in Bela Bela - and who up until last week would have taken part in the race himself - said everything pointed to something having gone wrong mechanically.

"The air race's safety standards are very high. Something like this could probably have happened anywhere. A pilot is powerless when something goes wrong with his plane. It was coincidental that they were busy with the air race when the accident happened."

According to Briers, who rushed to the accident scene, pieces of the wing lay over 100m from the plane's fuselage.

He said Flamingo planes were built in Brits and were the ideal planes for races like these.

The ill-fated plane was only nine months old.

Jannie de Klerk of Naturelink said on Sunday that Blignaut had been a first officer in Embraer 120 planes in the Air Force and would have been made a captain soon. He was engaged to Sharon Badenhorst.

Erasmus had become a father two months ago, with the birth of his daughter.

The Aero Club of South Africa, the organiser of the air race, refused to comment on Sunday.

After a bit of help please I'm getting frustrated, bought a vertex 710 and I want to use it with an intercom. I bought a PA200Y minicom which was suppose to fit to vertex's but doesn't.The supplier is happy to give me a refund but there must be an answer to this problem or maybe their not compatable with an intercom.

Terry:help:

here is some info that I have been able to get from a master in the know,

Please take note of "it needs careful adjustment"

Hope this helps.

"the 710 is the same as a VXA220 for connection purposes however it doesnt have a side tone so the volume control controls the side tone . It just needs careful adjustment but otherwise its fine."

Im not happy at all with the reception and transmitting of the new aerial on the undercarridge strutt as when I transmit it effects my skydat by shooting the egt's off the scale and making the alarm flash on while the button is pressed, i think the power generated by the radio coming out of the antenna is radiating to the instrument module box on the top of the engine.I might turn over the antenna so the long one is on the bottom but i will have to use my old wire one as I can bend it to shape so it does not hit the ground as the new fiberglass one will be too long.

 

McGuyver do you have any details on this mounting out of the keel tube extension, do you cut down an extension tube so it does not stick out as far, also would you clamp it or drill out the extension tube, I am also gathering this would only be suitable for the V rabbit aerial.

 

My new aerial that i got with the sst wing works nothing like my old one ontop of the kingpost on the ST3 wing, frankly i think it was a waste of money.

 

Cheers

 

Alf

This bracket is for the Vee Rabbit.

It is cast aluminium and fits into the wing keel.
