Thanks to all for your responses. Very much appreciated.

Looking for recommendations for for where I can obtain a reasonably priced leak down tester in Australia. Must have the recommended 1mm orifice.

To all those who took the time to respond. My thanks to you all. Appreciate all your points. On reflection, I will probably stay with the threaded plug, given the infrequency of oil changes.

Thinking of retrofitting a curtis drain valve to replace the drain plug in my 912 ULS's oil tank. Should make oil changes simpler and less messy. Has anyone done this and where best to obtain an aviation grade valve in Australia? Thanks everyone.

Thanks Nev and Skippy

Always appreciated.

Thanks so much for all the replies. Have got the plugs to fill the central valve holes and will use a step drill to created the offset holes. Practised on an old rim and it woks perfectly.

Thanks to all who replied. Always appreciated.

Thanks Dan

Very useful info and hope to incorporate into my aircraft

I need to obtain the small spring inside the flap lever of my VG. Any ideas where I might get one in SE Qld?

Does anyone know where oil tank drain plug washers can be sourced on the Sunshine Coast?

My Savannah VG came with centrally located tyre rim valve holes. The available tubes all have right angle valves which are offset and when forced to  fit the central rim holes, are placed under a lot of sideways pressure. I am going to drill new offset holes, with a step drill, in each rim. Would appreciate any advice re potential problems that I may encounter?

Hi Andy and 409tonner

Thanks so much for your replies. The group you recommended 409 (Convoluted) were great and I have ordered the fire sheathing at almost a third the cost quoted to me by a Brisbane based aviation part supplier. After a lot of searching was also able to find a group in WA who were very service orientated and able to supply all the Oetiker clamps + clamping tool I needed  (autopartswholesalers.com.au)I am using the single ear stainless clamps as recommended in the excellent two part article in the Rotax Owner forum (Rotax 5 year rubber replacent; My Savannah uses all rubber fuel and oil hoses. 

I am currently completing the 5 year rubber replacement on my 912 ULS / VG Savannah.

Rotax and other aviation sites seem to recommend using the Oetiker brand stainless clamps for fuel and oil lines but they seem to be very hard to obtain locally (Qld). Does anyone know of a good supplier?  Alternatively what other types of clamps are owners using? 

My engine does not have any fire sheathing on oil/fuel lines and will add this as hoses are replaced. Can anyone recommend a good supplier? Thanks for your thoughts.

Thanks Mark

Appreciate the advise

Thanks Mark. Is replacing the seals a difficult job and do you know if there is a detailed exploded view of the brake system available 

Recently had a seal in my left side calliper cylinder fail and dump the mineral oil. Can any member advise of any issues that may make repair of Savannah disc brakes difficult? As all the pads are pretty low, will be replacing all the pads and seals for both callipers and master cylinders. Thanks in anticipation.

Thanks Peter

I live on the Sunshine Coast and wondered if any Member might know of a VG within 100km I could have a look at. I am 6' 1" and concerned I might struggle a little for headroom? Any opinions also appreciated.

Bill, when I had my Xair I got my tyres from here Trailer Parts | Garbutt | NQ Wheels & Castor Supplies

I tended to pick up a few goat heads so got the heavier tread. They worked very well.

Jason

Thanks Jason

Will try them tomorrow. I have managed to find one tyre from All Mower Spares in Camden, so two to go!

Bill

Kenda is certainly one to try.

 

Tyre suppliers specialising in go karts. quad bikes, etc are also worth checking (some get very "twitchy" when you mention aircraft - best to try to avoided)

 

Word of warning - aircraft tyres should not have "aggressive" tread:

• Will pick up & fling mud stones much more readily than a smoother/road type tread
  
• Will tend to dig in/grab in a side drift situation, rather than slide over surface.
  
• Will have a higher tendency to rotate/windmill in flight especially if spats/fairings fitted.
  

You will have noticed that certified aircraft tyres usually just have paralegal grooves

Thanks for your advise Skippy. Makes plenty of sense! Appreciate all the other responses too.

Bill

Hi All, does anyone know where I can get new tyres/tubes for my Xair locally? I have checked the web and it seems most of sites are online tyre suppliers getting their stock out of the USA. The original tyres are 4.80 / 4.00-8 (4 ply) D602 Barrow Deestones. Would prefer to get a slightly wider/aggressive tread than the stock Xair tyres to make them more effective in softer coditions. Any hel appreciated.

Bill

Thanks Everyone for your advise. It has been really helpful and especially to Waraton ( I have messaged you my phone contact)

Bill

They are probably "mountain bike" shocks.

There's various sizes on ebay. 190 x 50mm DNM DV22AR Coil Spring Rear Shock For Mountain Bike Bicycle for sale online | eBay

Any info on make/model written on them?

Thanks Downunder,

I will see if I can get a serial number etc off them

Bill

Thanks Waraton

I'm a bit new to this. How do I private message you my contact?

Bill

Hi Everyone

I want to replace the shock absorbers and springs on my Xair's main wheels. They look a bit like motorcycle gear. Anyone got any ideas re what they are or had experience buying/replacing them? Thanks

Bill
