Can someone advise me whether it is possible to lengthen or replace the ribbon cable on a 12-22R receiver and if so how?.
I need about another 3inches (75mm)


Thanks

You have to make the cable yourself when the unit is new so there is no problem replacing it. The cable is made up of 2x5 Dil IDC sockets which can be bought from an electrical component supplier, and the appropriate cable. How to make the cable is in the instructions; you just need to make sure you get the sockets the right way round.

I'm not sure if lengthening it would cause any problems but my guess is that it would be fine. If the unit is second hand there is a good chance the one you have has been cut down anyway.

Thanks,
yes I can make up the cable, but how do I disassemble the 12-22R, to get at the IDC socket which is in the receiver?

Thanks

I think Siclick is confusing the 2.4 and earlier 35/36/72 Mhz receivers. The ribbon on 2.4 receivers and switches is built- in unlike the earlier DRs which plug into the receiver. You can buy this ribbon cable at any electronics store, cuts with scissors, red trace polarises it.
Remove the Rx cover and take a look, as far as I can remember it is NOT soldered in but clamped. I think its the same for the switch. It MAY be afactory job tho ! DG

No factory job required, David.

The old style plug is still there but hidden within the plastic casing.
You just need to unscrew the plastic cover ( both Rx cover and switch cover ). Then remove the plug from the IC board and open it by pressing the side tabs ( gently of course ).
Replace the old ribbon cable with the new one.
Be careful with the polarity and make sure that you clamp it properly: each fork shall punch through in between the cables of the ribbon or you might have a shortcut.
When you are satisfied with the position of the plug forks, finish the clamping with a vice.
Plug back into the IC boards and close the casing...

Thanks Oli and David,
Yes I am familiar with ribbon cable, it was just that I did not want to force the 12-22R receiver apart, without knowing what problems it may cause.
After a bit of work it came apart easily, it was just held by the number of pins. Replaced the cable with one a lot longer, and it works perfectly.
Now however I have the receiver set up into my SM Viperjet (the large one)and to change the subject now to find out why I have a bad air leak on the gear doors, and after that
to check the retracts.
Oli when are you flying down this way???

Best wishes
