FPV RC Car Post 2/2 - The build

Pre-Info on certain parts:

The transmitter listed in the shopping list is a 1.5 watt transmitter. If you read the reviews, you will see it "burned up within 15 min". You MUST create a heatsink and have a fan blowing cool air over it or else IT WILL BURN. Mine even gets warm with the heatsink, but it is never too hot to touch.

My Heatsink:

Now I will upload pictures and explain what I did. This project was as DIY as I could possibly make it.

First, install the metal upgrade kit for the RC car's main drive shaft. This -WILL- break eventually if you use the plastic one at high speeds. I broke mine originally.

The 9 volt battery to power the heatsink fan for the TX will fit nicely on top of the RC car battery.

Once again, I made my power brick for the RX and goggles DIY. I used an old 12V router adapter.

Connections for the goggles and the RX.

Goggles: side

I would suggest writing something like this. Especially if you are new to FPV with goggles, as I am. Using goggles is like trying to stand on one foot with your eyes closed. Because you can not see anything around you.

Circuit board for the screen.

Magnifying glass is required for your eyes to focus on the screen at such a close distance.

Cable management is great due to the large amount of free space inside the car body. There is also, the 9V battery extension for the heatsink fan.

I will be updating this, as I myself have not finished it. I just ordered the camera, all that is left is the battery then I am good to go. For a car under $300 this is pretty substantial. The top speed should be about 30mph and you also get 4WD with this car. The remote is stated to have a range of "more than 100m" but I have not been able to test this yet (no fpv and not a large enough open space). I have also been looking into antennas and found a pretty beefy one for not too much money.


I will probably get this once I get a tripod to mount things on. Since I have a 1.5 watt transmitter, I should have no problem with range. I may also purchase a 2 watt wifi booster and hook it up to the rc car's remote as it also runs on 2.4ghz.


Update 1:

 Had to move the plugs and hardwire it to save space
 Everything fit nicely!
