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.

Hi everybody,

I am trying to use my Futaba FX18 as a trainer, with a Spektrum Dx7 as master. It works but channel assignment from one brand to another is not the same. Is it possible to reorder correctly the PPM signal ? I have a couple of PIC (12C508). Would it be easily done ? Or maybe one of you already done it ? Can you give me some hints about doing ?

Thank you,

Loïc

Bien sûr, c'est en Wallon ...

Hey une fois, merci bien pour ton lien...

I built your little circuit, and I get the LED flashing when it receives a ppm signal from my Futaba radio. Now I'm wondering one thing : Can I feed the PIC output (5v) directly to the trainer port of my Spektrum radio ? I cannot find any specification about trainer port input voltage...

Hi, Loïc

Just a little scoping at the trainer port output will confirm ...

don't you think ???

either way, some series resistance to limit current from the Pic is a good idea ...
