The Lightest DJI FPV Setup with Naked Vista (Only 15.5g)

The Lightest DJI FPV Setup with Naked Vista (Only 15.5g)

By making Caddx Vista “bare”, you’ll be able to shave virtually 10 grams off your DJI FPV setup which is a big flight efficiency increase to any micro FPV drone. I’ll discuss what a unadorned Vista is and the issues to concentrate on.

A unadorned Vista is mainly the Caddx Vista Air Unit with the heatsink eliminated to make it lighter. The weight distinction is definitely fairly important because the heatsink takes up half of the unique weight (9g vs 18.8g).

It’s helpful for micro quads like 2″ and three″, as a result of each gram could make a noticeably distinction to efficiency. And these small FPV drones are usually brief vary flyers anyway, so decrease energy ranges are sufficient.

The Vista is just not designed to run with out heatsink, it’s exhausting to say what impact or injury the warmth can do to the Vista in the long term.

I don’t actually suggest performing this hack, however when you don’t thoughts damaging your Vista, and need the lightest doable DJI FPV setup, you may give this a attempt. You will hear individuals say “oh I’ve 5 quads operating bare Vista for over a 12 months now and they’re all high quality”, after which you should have different individuals say “mine died inside per week”. So don’t simply take heed to individuals, perceive the danger and determine for your self.

Mine really acquired so sizzling after I was engaged on it on the bench, it began placing out smoke solely 3 minutes after being powered on (by some means it survived and nonetheless works). Make certain there’s good airflow to the air unit both when you find yourself flying, or engaged on a bench. I believe most individuals use 25mW or 200mW energy ranges solely, increased energy ranges will generate extra warmth.

Note that by eradicating the heatsink, the boards additionally turns into extra uncovered to bodily broken.

The lightest DJi FPV system suitable digicam is the Caddx Nebula Nano, at solely 4.5g. However the picture high quality is just not nice and it solely works in 16:9 mode, so that you may need to improve to the Caddx Nebula Pro which is pretty much as good as the unique DJI digicam, and it’s 6.1g which isn’t too unhealthy.

As for antenna, you possibly can use a dipole which is the lightest, however to get first rate vary, a CP antenna is most popular. The lightest one I can discover is the BetaFPV Air LHCP.

With Nebula Nano and the Air antenna (with 4 screws and standoffs between the boards), makes the whole weight of my bare Vista setup solely 15.5g. The weight is just like an analog FPV setup 🙂

Here’s a helpful video demonstrating how you can take away the heatsink and the blue thermal grease. You may additionally want some {hardware} for mounting, the stack holes are for M1.5 (1.5mm diameter thread) screws and nuts.
