Question 1

Do you think this camera can be adapted to run on a model train car in HO scale?

Accepted Answer

Can it be done? Probably. Should it be done, probably not.

First of all, this does NOT record anything. It transmits a live video feed over 5.8Ghz radio waves in a proprietary format. This is designed for to fly drones and RC planes from a first person view (FPV) and requires the DJI FPV Goggles (v1 or v2, but not the DJI Goggles2) to work and configure. It also doesn't record or transmit sound. For a train that runs on a set track, I suspect you want a small action cam to record the video.

Second, these video transmitters are designed to work in drones or RC planes and have lots of cool air flowing over them. They get hot without active cooling and will go into a low-power mode that transmits about 5 frames per second.  Also if your train has plastics that soften at low temperatures, that could be bad too. If you want to put the transmitter in a car and set up a fan to blow air on it, that could probably work, but that is even more modifications for you.

You can find diagrams of the exact dimensions of the video transmitter (vTx) and camera on Runcam site. But the vTx is 29x29x13mm and the camera is 19x19mm at the back and 14mm across at the lens. It is also 19mm in length. The camera will probably fit in a HO scale car, but the vTx may have issue, especially if you need to add a fan to keep it cool.

Third, it isn't powered by a battery. The video transmitter (which powers the camera) requries a DC 7.4v-26.4v DC  input and consumes 4-9watts of power (depending on the power setting of the video transmitter). While an HO scale train will operate at that voltage, you will have to check if your system can provide the additional amperage required for that power. It is very possible it will, especially if you run it on its lower transmission level, but it is something to keep in mind if you already have a train and other things drawing power.

Basically, you can probably find a way to put it in a car, but I don't think it will be of much benefit and it probably won't do what you are hoping it will do.

Question 2

Can you connect it to your phone

Accepted Answer

Not like you are thinking . You can broadcast out of the Dji goggles 🥽 or smart controller. The cell phone usually requires a third party app.
