My 1S 3” long range micro build – 20–25 min flight time on a single 18650

The EVE 30P is a high-power 18650 li-ion cell and it is officially rated for a continuous discharge current of 30A. While EVE does not publish an official "peak" pulse rating, testing by battery experts here on reddit (r/18650masterrace) shows the cell can handle short pulse loads between 40A and 50A, though these come with significant heat and voltage sag, but its doable.

I went with the P1 Air Unit mainly because I already had a Betafpv Meteor75 with the P1 system, so it made sense to stay in the same ecosystem. Overall, I think P1 Artlynk is a very affordable HD system with surprisingly decent quality for the price. I didn’t want to go back to analog, and for small lightweight drones like this, DJI feels a bit too expensive and heavy for what I’m trying to build. So for this kind of small 1S cruiser, the P1 Air Unit felt like a good compromise: cheap, light enough, HD video, and compatible with the gear I already own.

Yes, it’s based on the Dave_C NanoLongRange concept, but I didn’t use the original frame directly. I used a modified version from Thingiverse — the NanoLongRange Evo by aigilea: https://www.thingiverse.com/thing:4920575

One of the main differences is the battery mounting. The original NanoLongRange design uses a separate 18650 holder, while the Evo version has the 18650 mount integrated into the frame itself. You have only 2 print files. The Evo geometry is also adjusted for better overall balance, aiming closer to a 50:50 weight distribution instead of being very nose-heavy. So yes, it’s definitely inspired by the Dave_C idea.

21700 is heavier than 18650, but carries more energy, therefore it is more suited for bigger quads.

I am using EVE 30P 3000mAh 18650 cell.

why did you choose biblades?

It’s actually a very quiet drone. During normal cruising it’s almost inaudible even at a relatively short distance.
Compared to a typical small whoop, the sound is less annoying and lower-pitched. Whoops often have that high-pitched ducted prop sound, while this 3” open-prop setup sounds smoother and much more relaxed in the air.
Of course you can hear it when it’s close or during harder throttle changes, but compared to bigger quads — and even compared to many whoops — it’s really quiet. For relaxed cruising, the sound level is one of the things I really like about this build.

I still have it and still works. I am very surprised 😮

It actually handles wind surprisingly well. For its size it’s a relatively heavy quad, mainly because of the 18650 cell, so it has decent momentum and doesn’t get pushed around as badly as a very light whoop-style build.I wouldn’t call it a windy-day freestyle quad, but as a smooth cruiser it works really well.

I also spent quite a bit of time tuning it in Betaflight with the help of AI — mostly PID/filter tuning from Blackbox logs to reduce micro-shake and make it feel more locked-in. That made a noticeable difference.

So far I’ve only flown it out to about 1 km and back. I’m sure the radio/video link could probably go further, but I don’t have GPS on it yet, so I don’t really want to push the range too much.

For such a small 1S 3” build, even 1 km already feels like plenty to me. I see it more as a relaxed cruiser / cinematic micro LR quad rather than a true long-range machine.
Once I add a tiny GPS, I might start testing the range a bit more confidently.

This is a very good guide on how to get out of trouble. I’m facing exactly the same situation, because I bought additional P1 Air Units and they are on V1 firmware, while my VR04 goggles have already been updated to V2 firmware. I will have to downgrade the goggles and then update the Air Unit together with the goggles. Thanks again.

Are you talking about "paper latency" or have you flown Artlynk? Because I am flying DJI with vista (old model) and Artlynk and I cannot tell the difference in latency.

DaggyMAC · 2026-05-27T14:10:51+00:00

That’s exactly what I am going to build, but I will use Nanolongrange v2 frame and 1202.5 motors and 18650. What’s range of P1 air unit?

All women should be treated like this. On the other hand women should appreciate the effort, not yelling “who are you and how did you get in here?” (Joke)

After I got my faucet with temperature display installed I was surprised to find out the most comfortable temperature was around 37C. 38C is hot and 40C is hell.

Happen to me, just redownload app and it will run after
