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:

UPDATE 8/7/2020: I never upgraded the motors, but several events have led me to mostly strip this frame of its electronics and replace them. See the new build here:

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!

Sounds good, thanks.

Having actually ran that setup on my 7", it actually works super well. I did a ghetto remix myself, and was super happy with the result.

- Fast cars made good use of the 35° bodge - running your camera angle works better for the more normal stuff, and that's my primary freestyle/cruising rig....
Thanks again!!!

Np, awesome 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.

Hmm, I think I'm going to get 1800kv xings for my new build:

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.

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.

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

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..
