Source One 6S 5"

This thing flies nicely, and looks awesome. I get about 4 minute flight times on an RDQ 6s 1250mah battery and Johnny props, which do fly well, but the dal props provide more power and similar flight times. I have not gotten F40 motors, but if I do I'll update this. I'm currently using 1700kv 2306 ecos. Here is my youtube channel:

If you have any questions or comments, let me know down below.

Here's my CAD files:

UPDATE 6/11/19: I added LEDs, but I'm currently stuck with 4s packs because my only 6s pack had two cells that decided to become 0.1v while on vacation. I also forgot to attach my camera ground to an fc ground while I had it apart... :/

I have since fixed my common ground issue but still have no 6s packs... :(

UPDATE 11/6/19: I got a 6s pack and my video looks better on punch outs now. I'm pretty happy with this build and will probably just keep it the way it is for a while. Also, here is a video:

Are the eco engines good or you prefer the F60 ?

JasonFPV0   Jun 05, 2019 

I do not have the F60, but they are fairly nice while the ecos are cheaper. The ecos are not bad, but the F60 are better.

tehllama   Nov 07, 2019 

As somebody who also runs both - completely agree on the F60 being better, but if you're willing to run 1900KV 2207's in places where the 1750 (more lik 1825KV) F60's would go, you can get almost the same performance, just at a slight efficiency and smoothness cost - but for $12 motors I'll take that anyday.

How do you like that GoPro camera angle for managing props in view? Gotten any feedback with the 7" arms?
Your build is definitely inspiring me to do something really similar, just bigger - just want to figure out if I should remix that GoPro mount to go higher on the uptilt angle. Thanks!

JasonFPV0   Nov 06, 2019 

I really like this angle mainly because it works well for freestyle, but I think it's pretty good for props to because they are just barely in sight. You can seem them just barely in this video:

. I'm actually using 5" arms and not 7". While this is a really, really tough frame I can tell that the carbon has weakened a bit over time from vibration and I can sorta bend the arms a little with my hands, but it's still really tough. If you decide to get a 7" you might not want to buy it from TBS because the carbon they use isn't the best, but it isn't to bad either. All the files for the frame are online and I posted some CAD files on thingiverse here: if you want to build off of anything I did. I'm not totally sure if TBS sells larger than 7" arms, but someone did make a 12" or something I saw on the Open Source Frames discord here: which is a great place to discuss ideas with other people. As far as the GoPro mount goes, it's sort of a pain to remix because I only have STLs of the files I used to create it, but I could remake one with a higher uptilt if you want me to, just let me know. I think the uptilt really depends on your flying style, and I think someone made a big set of deadcat arms if you want those to keep the props out of view. Hopefully this helped, let me know if you need anymore help. Also, that discord is really a great place to discuss these frames, I suggest you join. Good luck!

I'm a lot less disciplined about cruising at a reasonable pace, so I can get away with using camera angle to bodge some of the prop visibility. I'm in the same boat of only having computers that run primitive junk (3D Builder), so I'm at most doing ghetto remixes. I think I'm going to combine two slightly different ones (a steeper mount base, and the protectors that I already use), but that concept is spot on.
The use case is kinda different too - I'm trying to make a $250 answer to a DRL Racer4 Street... so I'm going to default to the camera angle I'm already used to on my 7" Floss rigs.
Thanks for that detailed reply - solid ripping too, that foliage rip is mint. Awesome stuff.

Is that foam? Hos is the vtx not over heating?

Like a channel switch on my transmitter? I feel like I tried this and it didn't work... I'll have to look into it.

e_z_chee_z   Jul 17, 2019 

there is a "switch" you have to buy that does the swtiching over a serial io pad on your fc. look up "realpit" on tinysleds

JasonFPV0   Jul 17, 2019 

Ah yeah, I'm not gonna bother with that. BF osd works fine.

FPVisioning   Jul 16, 2019  

So this is your new one after you lost that one that you were flying too high!

JasonFPV0   Jul 17, 2019 

Something like that lol.

FPVisioning   Jul 17, 2019 

The last video of yours I watched was that one over the lake and then you lost your quad like a couple days later right?

JasonFPV0   Jul 17, 2019 

A few weeks later yeah, but I lost it at a different place, not around there. I was on the side of a hill and flew to the other side, amd voila everything looked the same, trees everywhere. I couldn't find my way back before I lost video. So this is my replacement quad.

Whiffles   May 17, 2019  

How's that stack treating you on 6S? I've heard some concerns about running it on 6S packs but I haven't had any issues with mine.

Hm, my vtx is connected to the fc via the batt pads, and the camera is grounded to the vtx (powered off vtx) which means that it is also grounded to the fc, because all grounds are common, correct? Or is it different because of the vtx's filtered 5v regulator? Also, what does the osd have to do with the grounds of the camera and vtx if it is coming from the fc itself? Isn't that an internal problem? My theory is that the OSD chip is under powered on punchouts due to the motor's high amp draw. This fc is also known to have a small 5v regulator that can burn out easily... 1.5 amps if I remember correctly.

e_z_chee_z   May 26, 2019 

no you still have a common ground issue. even if the camera is powered off the vtx, you still need to ground it to the fc for the osd to work correctly. just move the camera ground from the vtx and ground it to the fc. trust me this is a very common problem

JasonFPV0   May 26, 2019 

Ohhhhh, I understand now, that makes sense. I'll fix it and let you know if it works. I can connect the cameras ground to both the vtx ground and the fc ground, correct?

KryptoSteel24   May 16, 2019  

Whats up with the go pro mount lol? looks funky

JasonFPV0   May 17, 2019 

Not sure if you're reffering to the actual shape or the sorta messy print, but I like that shape because it protects the gopro more. Its sorta messy looking because I had bad print settings and had to touch it up with a soldering iron. It broke in a crash the day after I took these pictures, and the next one I printed looked much better. I'll add some more pictures soon. You can also check out the mount model on the thingiverse link.

EDIT: Oh lol yeah I just realised how weird those touch ups did look. I need to add more pictures.

JasonFPV0   May 24, 2019 

I added two pictures with the new mount.

Do you get the corners in view when using the Falkor Mini 1.8mm lens?

JasonFPV0   May 16, 2019 

I actually swapped the lens for a 2.1mm, and I think the frame is still in view. I'll upload a DVR picture tomarrow if I have time.

JasonFPV0   May 20, 2019 

I added a DVR screenshot from a 2.1mm lens.

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..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
