Hi there

Bugger! My Gazelle had a similar "wing swing" mishap by the previous owner. They were able to make an "approved" repair 3 or 4 hangers with aluminum to replace the plywood. I have all the drawings etc somewhere which I will dig out and send send to you. Best if you have an email address? Not a nice job I am told...

Maybe the guy who did the repair will get in touch with you??? I know he is on this forum.

Thanks for the photo and back story! I do not have any manuals for the tail dragger version but I have asked a friend who has. I will let you know if I have any luck

I have a copy of the Maintenance & Repair Manual for the CA-25N Gazelle which I am happy to email you but first can you confirm you are not a scam?

Do you have a Skyfox CA-22 or 25 in Thailand? How did it end up in Thailand?

Cheers

Thanks Skippy - hard to see in the photo? Went for a fly today.  PTT worked fine on the pre take off call but then not working once airborne. Just working out how to remove the PTT switch - probably replace the rubber hand grip too. No idea where to get a new one? Bike shop?

Thanks for the reply and info Smokey!

Armed with the fact that PTT are cheap and available - I will have a go at pulling it apart 🙂

I suspect that the press to talk button on pilot seat control stick is failing due to intermittent transmit function. Has had a lot of use over last 28 years!

Has anyone got any tips on how to inspect/replace this switch in the Gazelle?

Thanks Skippydiesel. I am still hoping to be able to reuse the ones that are in the A/C but seeping... I will have a go at these tomorrow. I have no idea what the opening pressure is for these auto valves - there are very little specs available. Yes tanks will be low level for test.

Hi Guys and thanks for all your great input into what might seem like a simple topic - but is not!

I have asked myself 'what is the purpose of the non - return fuel valves'.  All I can come up with is that the two main (high wing) fuel tanks are "self leveling" i.e. there is no valve to select right/left tanks which is great! If you were to fly/park at a weird attitude the NRV's would stop fuel from flowing back to the lower tank (and possibly overflowing if full)?

The Gazelle Maintenance Manual specifies a minimum fuel flow to the carbs of 500 ml/minute (combined total) which I will test once the new NRV's are installed.

The fuel pump is located after the collector tank and provides only about 4PSI. I'll let you know how the flow test goes!

These are the non return valves I was able to buy online:

Thanks for your help SkippyDiesel! I have bought a couple of non return valves from an auto shop which gives me the confidence to go ahead and  remove my original ones from the A/C and inspect the internals without the hazard of being grounded for weeks while I try and find replacements!

Has any owner of a Skyfox or Gazelle got experience with changing out the fuel non return valves located between the wing tanks and collector tank behind the seat? The rubber inside the brass fittings of non return valves are known to deteriorate with age but I can't find any info on where to source replacement parts. Is there a more modern non return valve I can use?

Thanks

That looks like a great solution! And gives you weather proof storage too. If I was not so far away...😃

Thanks Again Naish88 they have been very helpful!

One problem I have at the moment is with my wing tank fuel drain valve. I had a slow leak/weep and replaced the Curtis CCA-1550 drain valve thinking that would fix the leak. It did not! Turns out the brass fitting that the valve screws into has split - a previous owner probably got a bit too aggressive with the thread tape and/or overtightened?

I would like to remove the split brass fitting from the tank which might be a "finger filter". Has anyone ever had to remove this fitting from tank or have a drawing (nothing in the Service Manual)? Is it screwed in or epoxy resin glued in? Any knowledge would be appreciated!

Thanks Superfox and Nev.

I have now rebuilt my master cylinders using new 'O' rings from Transeals here in Perth - very helpful. Now working 100%!

I have also changed to using Dot 5 silicone purple brake fluid which Matco specify (most L2's use red hydraulic fluid)

Yes they are Matco MC-1 master cylinders which I discovered when I ordered 2 x MC-5 rebuild kits from SkyShop which are way too big.

So I now have 2x unused/unopened rebuild kits for Matco MC-5 master cylinders to sell cheap!

The reason I bought MC-5 is because that is what it says in the Skyfox Gazelle Maintenance and Service Manual. Oh well???

I also have a Skyfox Gazelle and want to repair a fluid leak/loss of function by replacing the seals in the master cylinder. I can find no part number on the cylinder. I guess it is MATCO but maybe MC-5? Does anyone know for sure what model master cylinder was installed in the Skyfox Gazelle?

I found a few references to AD's on RAAUS but no actual documents. I'll try giving the RAAUS office a call on Monday.

Hi All, I am new to member of this site, looking to purchase a Skyfox Gazelle. As part of my research I have found there are quite a few CASA AD's and Skyfox Aviation Service Bulletins for this model.  Does anyone know where I can get copies of all the SB's? I understand the company went bust in 1999 so who is supporting this model today?

Thanks for your help and I look forward to making contact with other Gazelle owners!

Cheers Neil
