pls help me, guys, with my Turnigy 9x!!!!

[kushlord]

hey guys!!
I am a person from India, and I am ambitious to fly an RC plane. I have purchased a Speed Build kit for the FT Mustang and will receive it soon. However, the issue is that my radio control, specifically the Turnigy 9X V2, has a problem. I accidentally cut the antenna wire running through the transmitter. And now I need an easy fix bcs money is tight, so I wondered if anyone could help me fix it. As you can see, the wire broke just below the antenna, and the pin in the module is bent
PPLSSSSS HELP me guys, this is my last chance to build and fly an RC plane

If the wire coming out of your transmitter is still the correct length then you just need a way to hold the wire in place, don`t really need the outside plastic piece.

1.This wire is located in the screen. Just carefully remove the screen from the wire. The length of the wire without metal insulation should be 31 mm. The control range may decrease to 300 m. 2. Disassemble the old router and solder the antenna wire. Solder it to the board.Glue the antenna with hot glue. Before flying, check the actual range of the transmitter with an assistant.

actually i did try to range test it without doing anything but it is not working however i will try to do the second method

 

[kushlord]

the problem is that i cant get the wire out from the antenna so maybe i buy a new module and receiver which is second hand

The picture you had above is really small and doesn't show how the antenna is attached to the board. can you share another picture showing the board from a better angle?

 

[Shurik-1960]

You're making a problem out of nothing. Tomorrow I'll try to take a picture of what you need to do. I don't think you understood anything.I flew with this problem 10 years ago. 2 minutes of careful work and the transmitter is working.
Litter Bug , the antenna wire to the board is soldered at 3 points: screen, core, screen. The screen is grounded. BUT if you don't have a soldering iron with a thin sting at hand, these pads can easily be damaged by overheating.

Curious having a transmitter turned on with out the antenna would it burn out the RF deck, anyone know?

 

[Merv]

I agree with LB, you need better pictures.
Here are some videos repairing a receiver antenna. Repairing the transmitter antennas is exactly the same.

 

[Shurik-1960]

If the antenna breaks, the transmitterTurnigy 9X will not burn out- very little power. BUT the transmitter chips on 433, 915 burn out very quickly without an antenna.Their capacity is up to 1 watt.

This transmitter has been flying with a pin antenna for a long time. They gave me an old router and I soldered the antennas and wires out of it. I just pulled down the screen in the last photo, but it's better to trim it carefully.

Many radios use a connector to the board, and we can't tell from the picture. It becomes a simpler job if that is the case.

You should not run a transmitter without a proper antenna.

hey, thanks to reach out. actually i was trying to observe the board but the antenna wire broke out of the board of the module. now i am planning to take a new antenna. and the receiver too does not have the antenna. i am going to take it to a proffesional to soilder it so could you help me with the specifics of the antenna like is it omni directional or which dbi is the best etc. or could explain some other way to fix it because i dint understand what you said about the screen.

if you are talking about the module, well the antenna wire was just soildered on the module

 

[kushlord]

as you all said, i have uploaded some pictures of the module where the antenna was soildered, the receiver where the antenna is broken and the antenna wire from the transmitter

ahh, i got what you wnat to say. you want me to trim the wire so that there is no insulation just the signal wire

 

[Shurik-1960]

A thin wire with a 7-8 cm grounding conductor is soldered to the receiver. At the end, the wire is stripped from the ground wire by 31-33mm. EVERYTHING is flying and controlled. This has little effect on range.A wire from any antenna of the old router is soldered to the transmitter board. It works even better than with the original antenna. Repairs can be done in 5 minutes, and the topic stupidly lasts...lasts...

 

[kushlord]

hey everyone!! thank you for being so helpful, especially Shurik-1960. I have purchased a new antenna and will update shortly. it should work this time, and I will use the excess wire that was from the transmitter to solder it to the receiver and cut 31mm of insulator

i did not have an old router so i ahd to purchase a new antenna

 

[Shurik-1960]

I have not been to India.But there are plenty of junk shops in Europe and the USA. I saw a bunch of old routers there almost 20 years ago.
