G’day All,

Does anyone have experience with the Lynx intercom/headset system? I have very weak/distorted sidetone and suspect it the batteries. Apparently they are 6V 450mAh Ni-Mh.

I’m not able to source anything through Jaycar/BatteryWorld, has anyone been successful with replacing their headset batteries?

thanks in advance!

Could also be rf getting in the line,  disconnect the mic plug and test again, noise gone, problem solved.  Still there, try above.

Hey Flyboy, many thanks for the tips! I’ll try that out.

G’day Radio Guru’s,

I have a Microair 760 Radio fitted to a gyro which is working fine with a Lynx Intercom system. 
 

I do however get an annoying momentary (1 second) loud high pitched tone through the headset the moment I turn the radio on. After which it goes away and the radio functions fine.

Is this normal? And for comparison, are there any Microair 760 owners here that experience the same thing?

thanks in advance!

G'day Aviators,

Does anyone use Lynx Headsets? if so, do you also use a battery charger? and which type do you use? i've learned that these headsets have internal batteries which power amplifier circuits for sidetone and the mic and may require periodic charging. One of my headsets has low sidetone so I think I may have killed my battery from neglect over 8 years of not placing it on-charge between flights 😞

Additionally - has anyone ever replaced these batteries before?

Any info would be greatly appreciated.

Cheers.

I get it from the company that used to be Archer Fuels. I can't remember their name just now but they are located on the bend of Ingleston rd in Tingalpa. It's something like Pegasus aero fuels. They have good prices too.

Thanks Scott & much appreciated.

Does anyone know where I can buy Aeroshell Sports Plus 4 oil in SE QLD?

Thanks in advance :)

Surprisingly, I've actually been able to purchase a few items from RS Online and Element 14 at reasonable prices - but I do agree, a lot of their pricing isn't competitive.

It always pays to compare pricing once you find the exact specs/part number, it can be a real eye-opener sometimes.

I was looking for a jaw-type drive coupling insert replacement recently, and my usually good local bearing supply house wanted $65 for it - yet AIMS Industrial is selling it for $17.97!

Thanks again Onetrack & good to know.

They're also called anti-vibration mountings, vibration isolators, or rubber mounting blocks, and Mackay manufacture a large range here in Australia - but there are also a lot of imported types for which you will pay a lot more for.

You need to be able specify the loading, the use, the mounting bolt diameters and threads, and whether you need mountings with studs cast into the mounting, or with nuts cast into the mounting.

 

It pays to acquire a view of the manufacturers catalogue to find out what they make, and their specifications for each of their products.

 

I use either Flexible Drive Agencies, or my local industrial bearing supplier, to provide my rubber mounting needs. Surprisingly, eBay often has good rubber mount offerings. You can also order online from RS Components or Element 14.

Hi Onetrack,

Thanks very much for taking the time out of your day to write such a probing & detailed reply. These links are really helpful and I should most definitely be able to source something.

Really appreciated and have a great day!

Any good nut and bolt shop or bearing shop has them, all sizes and types

Thanks Flyboy :)

G’day Aviators,

could someone here please tell me where I can buy silent blocks? Pictures attached.

I have one that’s worse for wear. Any information would be appreciated.

cheers,

Andrew

Hi Ozzie, we have an airfield just south of Prosepine and could easily fit the Gyro in one of the hangars, also basic accommodation if needed. 

Cheers Ian

Hi Ian, Thanks very much for your reply! i've just sent you a PM.

Cheers,

Andrew

Two blade Gyro , would fit in a shed !.

Try giving your size,

spacesailor

Hi Spacesailor, thanks & good question - yes it would definitely go down the wall of a shed (picture attached with dimensions).

cheers

Hi All,

Looking for some help. I'm planning a trip to Airlie Beach (departing Brisbane) in late September and seeking some temporary hangarage for my Gyrocopter (approx 3 weeks) somewhere that's near to Airlie Beach.

Shute Harbour, Prosperpine and Bowen Airfields come to mind and I would be so grateful if someone could help me out with a small corner of a hangar. I'm obviously happy to pay a reward in return :)

Thanks in advance!

Ozi

Thanks for all the constructive feedback gents, I really appreciate it - tailwinds 🙂

Silicone rubber hose is superior in every respect over "natural" rubber hose, as regard both low and high temperatures, has higher pressure ratings, is more resistant to UV light, and stays supple for longer.

 

Probably the weakest point of your installation is the cable ties. Make sure the cable ties you use are UV-resistant, and able to cope with the Australian sun. The white nylon ties do not have the UV-resistance of the black nylon ties.

Thanks Onetrack for your feedback and much appreciated mate, I generally replace all my zip ties annually so it's not a problem 🙂

I've used Aeroflow branded hose for several years.  https://www.aeroflowperformance.com/silicone-hose

I pulled some hoses off while changing coolant several months ago. It looks and feels very good, as new.

This hose has the "woven" reinforcement in it.  

I think it compresses less than rubber over time.

 

Your install looks good OT!

I wouldn't mind having one of those thermostats.....

Hows the ceramic exhaust coating holding up?

 

Hey thanks Downunder and that's great to hear. Yes the ceramic coating is holding well so far also thanks, it was well worth the $300 investment.

I've been using it for about 450hors and two and a half years without any problems.

Thanks for the feedback and that's great to hear 🙂

Hi All,

I'd love to hear anyones experience and any feedback good or bad regarding silicone hoses used on Rotax 912ULS engine and whether if this is appropriate? I recently completed a Rotax 5 year rubber replacement on my engine and replaced the one inch stiff ribbed style hose with a silicone one inch heater hose. This silicone hose flex (refer to pictures) easily meets/exceeds the temperature and pressure requirements of this system and there are no kinks when hot or cold. 

I would love to hear anyones opinions/feedback on whether if this was a good idea or not.

Thanks in advance!

Andrew

Thanks very much everyone for your replies & I appreciate it!

Hi all,

Can anyone tell me where I could buy Loctite Anti Seize 8151 (or equivilent) for use on muffler ball joints on a Rotax 912ULS exhaust? I was hoping to source some locally in Brisbane CBD area.

Thanks in advance :)

"Protection" ? - must be in a salty environment. My untreated 20 year old exhaust system may not look quite as "schmick" as new. Bit of heat discolouration about covers it but it is still in great condition.

no Skippy - i'm well and truly inland.

Is this coating guaranteed to give you an extra 10kts in airspeed? It looks pretty flash.

Onetrack, it's purely for surface protection and good looks. Guaranteed to make the machine looking more sexy now hehe..

Gates make top quality products, the Gates fan belts on Perth public transport buses last for 500,000kms. Their hoses are just as good.

Most Japanese cars run close to 100°C in normal operation, and go to 110°-115° on hot Summer days under load. When a temperature gauge on a Japanese vehicle points to H, it's definitely Hot!

Thanks for the suggestion Onetrack :)

Try the following Gates cooling/heater system hoses Part No's -

 

24216 - conventional

24916 - wire reinforced

24816 - silicon

28225 - silicon

28413 - long length

28420 - long length

26244 - silicon long length

28449 - long length

 

All, are 25 mm, will have different pressure ratings (do not over specify you will be adding unnecessary cost & weight)

Thanks Skippy

Hi Ozzie - did you check out the Gates catalogue, https://www.gatesaustralia.com.au/~...application-catalogue-aus-nz-january-2018.pdfas - I suggest ?

 

Pages 14, 15,16,17 all have 25 mm/1 in hoses listed. Try talking to your local Repco they are all agents for Gates products.

 

Oh! and by he way dont know where you go this idea from "unlike car radiator hoses which are only good for 80-90'C " its not only not correct, its not even logical - car cooling system must be able to withstand prolonged temperatures above the boiling point of water (100 Centigrade). True the cooling system will, under light load cool weather, keep the system below this but it must be able to withstand high load hot ambient conditions as well.

 

I am confident that no Rotax engine operates above normal automotive cooling system temperature range.
