Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.



Setting futaba 12fg to 12 channels PPM


Recommended Posts

Hi, I´m trying to have 12 channels on PPM with the Futaba 12FG tx, I´ve read this old post from here:

http://www.rcuniverse.com/forum/m_6592923/.../tm.htm#6592923

I´m currently using firmware 1.6 newer than the one on the link. If I go to the "Frecuency" menu there I can select on PPM mode 8 channel standard, or 12 channel. When I select 12 channels the changes doesn´t take effect, does anybody knows how to set this properly?

Normally you should select 12-channel, the radio should ask confirmation, then ask for transmitting (just like when you change transmitting channel). Once you turn RF on, you should have the 12-ch PPM.

I know but with the 12ch on PPM there is no such message, when I select it nothing happens, and if I exit the menu with the 12 ch ppm option marked, I see that the radio has returned to 8ch PPM :( .

Do you have this radio kilrah? If so could you try it too?

I have a 14MZ, so as the input method is a bit different I can't really guide you step by step... but apart from that the software is identical and the menus very similar, so I can hint.

I enter the frequency setting screen, select the modulation menu, and arrive on the page where there are the PCM G3, PCM1024 and PPM options. Under PPM I have Standard PPM, which changes to Reverse PPM when clicked, and 8CH PPM that cycles to 12CH PPM (1.5ms neutral) and 12CH PPM (1.3ms neutral). After changing, I need to select the "Enter" button to confirm, just like I'd have to do if I had selected PCM1024 instead for example. Then I geta "Modulation type is changed, sure?" screen. I confirm, get the channel relocation page where I say no, and then I get the "Transmit?" screen.

Try to simply do just like you'd do to switch to PCM.

Great, that what I was doing like you did, but I now realized that instead of hit the Enter buttom on the servo neutral (last option on ppm 12 ch) you have to go again to PPM and press enter, then the tx warns you that you´re changing the modulation settings and all that. Now I have 12 channels on the Servo Monitor with PPM :D :D

Many thanks Kilrah, this is a great Radio TX :D :D (I´m very happy)
