Skyfox Gazelle Press to talk button replacement

[Neil Denmark]

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?

Hiya Neil

 

They are just a PTT from jaycar be a few bucks worth and usually soldered on,

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 🙂

Hi Neil,

The PTT is a very simple spring loaded switch that only makes electrical  contact when you press & hold  it.

If its failed, after many years of service, it is likly beyond economic repair.

As Smokey said - just research what your local electronic store (JayCar in Australia) has to offer. They likly have many diffrent sizes & styles to choose from. 

Measure the dimensions of the old switch and use this to narrow your search.

PTT from JayCar is the centre one above😈

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?

No experince on your aircraft type so pure speculation on how to remove;

You will need to expose the bottom of the stick, to free up the PTT wires. This may be as simple as unplugging spade/bullet connectors & removing cable ties OR you may have to cut the wires. If cutting do so with care and a plan to reconnect/install.

Its likly that once wires free, you can then slide (with difficulty) the hand grip up - the PTT switch will go with it.

Once the handgrip is off the stick removing the switch should be easier.  depending on how the switch has been secured Vice Grips, used with care, may be your friend😈
