Thanks Guy and Nev, when I built the Skyranger I remember cleaning up the inside of the bore with a dowel wrapped in fine wet and dry, as per Greg Robertson’s’ recommendation. So I guess it’s done well for 10 plus years of service…given it’s only aluminium…

Hi Guy,

thanks for the info and photos, it’s a good heads up on what I might be facing.
Could you see the bore was damaged or did the brakes just not work ?

thanks 

Michael 

Still waiting on Flylight to come back with a delivery date…

🙁

Hello Guy

Ive got exactly the same issue with my Skyranger swift. As you probably already know, there is an overhaul kit available from Flylight , but there is some doubt about getting the right kit, apparently.

My Swift is 11 years old btw.

Its a pity we can’t just buy new o rings.

 I’m doubtful that Flylight manufacture the hydraulic unit. I’m guessing it’s from a moped or similar.

And yes they are slow on emails. I’m waiting on a reply…

would you like to send me a pm?

cheers

Hi Skippy

thats brilliant, many thanks, 
Mike

Ok, so if the larger sizes are difficult to find, do you use screw  clamps on these? As found in automobile apps?

Skippy, if I could ask you a question, do you use Oeticker clamps for securing the hoses , the EAA hints for home builders thinks they are a good idea?

Skippy, you are a gentleman, many thanks for all your research and tabling the contents for mugs like me. It is appreciated…

Hi

i agree with Scott, I’ve had both engines in my Swift and the performance difference is considerable, especially in the climb.

Mike

Thanks for the responses guys, this may throw a bit more light on it,

Skyranger has a larger than 600 x 600mm  ali  plate for the antenna.

I promise not to disconnect antenna and transmit.

I set the mike gain to what the light speed guys told me , all the way down and undo 1/4 turn , at least I think that’s what they said...

Have you looked at adjusting the mic gain on the lightspeed headset? 

Yes , gain fully wound down

All good information. Something we are missing here.

hmmmmmm,

 

and the intercom between the two pilots is good ?

Do two different types of headsets behave the same ?

 

"static" . as in just white noise ? like the same noise when the squelch is open on a radio  (with no signal) ?????

OR a pulsed static - noise ?

 

 

 

Yes static / white noise , just like open squelch ......

Hi If you one of the large 22,000 capacitors check that is still serviceable eg there may brown coloured fluid coming out of it or swollen / burst.  If so replace it.

Thanks Blueadventures,

I’ll have a look

if the intercom is operating normally and the only time you are getting excessive noise is when you press the transmit button and all you need to do is turn down the sidetone. You want the side tone to match the same volume as the intercom that way you are getting level audio.

Thanks Flyboy,

I’ll check that out

what is sounds like to me is that :

The radio and or intercom generates sidetone, and the voltage at the radio or intercom, when the radio transmits is falling below the regulator dropout threshold, and it is unable to take noise off the avionics / power bus , and the noise on the power gets passed to the sidetone. 

Either the voltage to the system is LOW (has a high resistance) , OR the alternator is under heavy load (sick battery?, OR the alternator has lost a diode or soemthing and is generatijng a very coarse waveform.  OR you have a common earth with the alternator and should have a separate earth, IE an earth is missing, or the radio pass transistor for the power supply is sick maybe zapped by a voltage spike, OR.....

 

more information questions : answer all questions yes or no. 

 

when you say noise...
is this a whine proportional in pitch to RPM ?

is this a staic noise sound proportional in rate to RPM ?

Is your transmitted audio clean ?

Is the battery  known good ?

What is the battery /avionics voltage at idle and high RPM ?

Do you have this same noise between two headsets on the intercom ?

Does this occur with a NON NC headset- IE a headset without any electronics in it ?

Is there noise on the received audio?

 

 

 

Thanks RFguy ,

ok the answers as best as I can think of;

1) no ,it’s not a whine noise at all.

2)Yes, it increases with rpm.

3) transmitted audio: I am told by other pilots when requesting a radio check that it’s a 4.

4) Battery is new.

5) I think the voltage at idle is about 14 volts, not sure at full song, will have to check.

6) No, noise is only on transmissions (When ptt activated)

7) Yes it occurs with a DC 13.4

8)No, recd audio is good.

Are you using a USB style charger for your electronics (eg an iPad)?

Depending on the design of the charger, they can cause a problem with feedback thru the headphones

Thanks, yes I do use a USB charger for the iPad, pcas and gps signal unit for the iPad.

i can easily check if these are an issue.....

Hi Downunder, yes it’s in a cool spot, seems the same in winter...

Hi all,

just wondering if anyone can help with this problem? I fly a Skyranger with an Xcom radio, when transmitting I am getting a lot of noise coming back through my headset.

it is worse at higher rpm, especially at climb out, noticeable but not too annoying at taxi and not there before engine start. The engine is a Rotax 912 uls.

I use a light speed headset. Thanks.

Thanks Paul, a timely reminder.

I think Facthunter has got it right, it is up to us. We don’t have to fly if wx is marginal etc.

I finally edited my video. In June 2013 I moved my plane from WA to Qld. I followed a front across and because so got favorable tailwinds. I cruise just under 90Kts but got ground speeds of 105 to 115 Kts because of the south westerly winds behind the front. The only adverse weather was on day three when I caught the front at Port Augusta and had to fly under cloud through a pass in the Flinders Range. Day one Katanning to Esperance to stay with friends. Day two Esperance (Myrup), fuel at Caiguna, Eulca wee break, Nullabor Roadhouse for fuel to Ceduna. Day Three Ceduna to Port Augusta and Mildura for fuel then Temora. Layover day four with friends at Temora. Day Five Temora to Narromine for fuel and then to Steve Hunt's farm near Warialda for lunch and fuel, then home to Kingaroy. All up with favourable winds the first three days the flight took 22 hours and I covered a distance of 2200 nautical miles. Enjoy the video.

I had eye surgery for short sightedness and cataracts and to fix a skin growing over the back inside of one eye, I had to talk the surgeon into it as he said my eyesight wasn't too bad, I knew otherwise however,

I could not believe the result after surgery, a couple of years later and I still can't get over how good it is.

If you contact me I could tell you the details

Regards

Mike

Hi Kyle

Looks like a very professional rebuild/ restoration, well done to you sir.

Mike

Hi ,

I've had cataract surgery in both eyes, all I can say is I wish I had done it earlier,

You won't believe the difference.

I was also concerned about my eyes being touched, but you don't feel anything,

Regards

Mike
