Newly finished Futaba FT-5E Coder Tx.

Post by JohnH » 13 Jul 2019, 05:05

I just finished the conversion of my Futaba FT-5E transmitter. I used Phil G's coder, S/C emulator and FrSky DIY 2.4G RF. It worked perfectly right off the board. I powered the transmitter with a 9.9V LiFe battery. I really like the LiFe batteries for my transmitters and airborne systems, as they are the proper voltage, and I can charge them up put the unit on the shelf and take it down a year later and go fly. It will still have 98% of its charge. Gotta love the new battery technology. :D .

I left the 27 mHz frequency label in place for Authenticity.

Should have put the S/C board on the front face to better see the LED's

Red button on top is the DIY module bind button.

Hi john
That’s very nice. Did you re spray the case or is it original?
Nice and neat, have you flown it yet?

Magnificient. Looks like an original panel meter up front. May I conclude that you used the original transmitter casing?

I owned a Futaba 5S in the sixties, not anymore in my possession that's why I 'm trying to 3D print the transmitter case using a internet picture as reference. Not sure though of original measurements.

Thanks for the comments. The transmitter case is totally original, and I connected the TXD output on the DIY module to the meter to make it functional. I also removed the telemetry switch and the LED's from the DIY to save space.

I am not familiar with the Futaba 5S, but I do have an FT-5D. If that is the same size case, I can measure it and post the dimensions.

I have not yet flown the 2.4G version, but the original 27 mHz version was extensively flown. I changed it to the 2.4G band because I was getting interference on 27mHz which caused a few crashes. I have two more FT-5E's, one is a RipMax and the other is MRC. I'll probably convert one of those also and keep the other in original form.

BTW, the lower switch is just a dummy. I had to saw off the switch body and CA the bat in place, in order to fit the battery.

Hi John,
The Futaba 5S transmitter is like in the picture. Lots of similarities. I.e. the logo, the panel meter, push button etc.

The panel meter I got is a 400 microampere, 35x15 mm display size. Is that comparable with the size of the original one? What I'm special interested in is the size and exact proportions of the FUTABA logo. Can you get met a good front picture and measurements?

Hi Henk,

Your picture of the FT-5S transmitter shows that it is the same as my FT-5D. I will get you dimensions and close-up photos of the Futaba logo and meter, which I am sure is the same as the one in the FT-5E.

Regards,
John

Henk,

Here are the dimensions and photos of my FT-5D transmitter. The FT-5D is identical to the FT-5S, except the 5D has a dual purpose meter. The meter normally reads battery voltage, but when you press the white button on the left, it reads RF signal strength.

The case dimensions are: 15cm X 9cm X 4.5cm.

The meter button has dual spring contacts.

The meter face dimensions are 35mm X 15mm. The button is to the left of the meter.

Marvellous John,

This is a great help in making my replica. Much appreciated!
If you ever come across an original F5E or F5S, the person who owns it wants to sell it and not unimportantly;the price is not to high I would be very interested.
