TBS Source One V3 (2204/2300kv Motors)

After cutting my teeth building micros, I finally made a 'big boy' quad....and I can't help but feel I went about this entire hobby backwards because building a 5" is so much easier than building a 2.5" or 3" quad!!!

Having spent the first 6 or so months of this hobby getting finger cramps trying to cram 20x20 stacks into tiny frames or, even worse, straining like a constipated Gilbert Gottfried trying to see the ridiculously small solder pads of 16x16 boards, working with a 30x30 flight controller and ESC is a piece of cake! No more old man squinting for me (ok...there's still some squinting)!!

Likewise, shoving the rest of the components (VTX, reciever, etc.) into the frame was piss easy!

I went with the TBS Source ONE V3 frame because of the cost and the solid reviews. As I mentioned, it's also my first time building a 5" so I didn't want to go all out and get an expensive frame like an Armattan Duck-Billed Platypus (or whatever its called called).

Alt Tag

The Source One a great frame; seems really sturdy and, as I mentioned, lots of space inside.

For the FC and ESC I got the Diatone Mamba F405 with a 40A ESC. I've had, knock on wood, good luck with Diatone electronics and this has been no exception. Big solder pads (though not as big as the HGLRC Zeus AIO - those pads are massive) and easy to set up. This particular FC comes with Betaflight Version 3.5.7 installed and since it flies well and I have no desire to run 6S on these motors I haven't bothered to upgrade to Betaflight 4.2 yet (or even 4.0 with it's fancy RPM filters).

My understanding that for this size quad, most folks fly 2207 or 2306 motors but for my first 5" deliberately went a bit under-powered with 2204 2300kv motors from RotorGeeks. I feel like this approach worked for me - these motors still pack a decent punch (see the video) but I've also had the odd situation when I'm flying where I think "ok, it would be nice to have a bit more power here". I'll probably replace the motors for 2207/2306s once I'm more confident with my flying.

For the receiver I went with my trusty old Frsky XM+ (though I always have to upgrade the firmware).

I really like Rush FPV video transmitters and this one originally had a Rush Tiny Tank but because I was awed by the space in the frame I upgraded it to a Rush Tank Mini which is completely overkill for me as I don't do long distance at all. That said, man the Tiny Tank is cool! It's really easy to set up and use and it's the first VTX I've used where both the LED indicators on the VTX and the button set-up make sense.

I like the image quality of Caddx cameras and went with a Ratel. As is always the case with FPV cameras, image quality is almost entirely subjective so go with whatever brand and model you prefer.

Finally, this was the first quad where I was able to try a variety of different tri-blade props. I tried;

HQ Prop ETHIX S3 5x3.1x3
Azure Power Johnny Freestyle 4.8x3.8x3
Gemfan WinDancer 5043
DAL Cyclone T5249C Pro

Alt Tag

Ultimately, as much as I love how the GemFan WindDancer props looked with the Skitzo Galaxy pattern - see above (chef's kiss) - I felt the Azure props were my favourite - smooth (minimal jello), quiet and really responsive. Your millage may vary.

Overall, this was a fun, simple build that's also a lot of fun to fly!

Build looks good! I would 100% recommend upgrading to BF 4.2 tho. Having RPM filtering is crazy nice. on one of my three inch builds, i moved the sliders to 2.0 and it flew so well that I didn't even touch the pids. I believe you're running BLHeliS, and Jazz maverick firmware is free and crazy easy to install

jpeterson - thanks for the compliment and the advice! I recently caved and got a Crossfire module for my transmitter so I have to change the receiver in this guy anyway so that's as good a time as any to upgrade to BF 4.2!

yeah man do it. Ive really been wanting crossfire, the fear of a failsafe sometimes stops me from getting some cool footage, but the price of the receivers is just hard to swallow

Any heat issues with the Insta360 Go? That looks like some solid protection, but it also looks pretty hot.

So far, knock on wood, not at all! I've been lucky to get a lot of flying in the last two weeks and it's been pretty hot here (85F/30C) but no issues with the Insta360 GO. I think as long as you're flying the airflow (even with the TPU cover) is enough to cool it down. Definitely recommend Brian's mount if you're looking for one. 👍

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..
