I love this little quad so far, though it definitely needs some tuning. I started with HQ 3x3x3 props, but switched to Gemfan 3016x3 to try and combat voltage sag. I set a throttle limit of 80% and it seems just right for cruising/light freestyle. Once it's tuned I'll upload some goggle DVR. I've only gotten two of the packs I ordered so far. I have some different brand 450mAh 4s, and some 650's on the way.

The VTX is mounted directly to the Canopy by two long M2 bolts (I forgot to measure them). There are two posts with 20x20 spacing, I had to drill them out to get the bolts to thread. So far its holding very tight, but we'll see how it holds up in a crash. The camera is mounted using the included long screws.

Update: got some more batteries in today, they all performed much better. The pulse packs will be reserved for cruising. I switched back to the HQ 3x3x3 props, removed the throttle limit, and regained some much needed power.

Some DVR for anyone interested, it's not completely tuned yet:

can this build using dji controller? if do what is the wire configuration?

Sconeboy   Jul 08, 2020 

Yes, you connect the sbus pad on the vista to the sbus pad on the flight controller.

i am new on this hobby. is it possible you can draw a diagram for all six wires from the vista to the FC?

I finally finished the build and really love this thing! I do wish the frame and canopy were little more compatible but if I ever have time I might eventually design my own frame to fit the canopy better. But for now this thing is really great. Super light and super powerful. Regarding when your propwash, I was able to get rid of most of it by turning up the filter sliders each to 1.7. See if that helps you at all. thanks again.

Can you share your PIDs? I know you said they're not perfect but I'd like to have a good starting point. Thanks

Uploaded a screenshot, currently running BF 4.1.1. I have that frame and canopy aswell, but decided they were too heavy for what I was going for. The the Twig XL Vista canopy is ~7g heavier, and the frame is ~11.5 grams heavier, and thats not including the arm bumpers/wire ties.

Thanks so much! Ya I just weighed mine and it's 25g heavier than your setup and I'm not using any of the extra TPU stuff. I'll be glad to shed that weight, as much as I love the twig frames.

If you have some time, for giggles, you should just give 3.5.7 with stock PIDs a fly.

So glad to see this frame and canopy for the vista. Thanks for the tip. I used the TwigXL with their Vista Canopy and it's literally 40 grams heavier than your build. It's built like a tank which is great but it's way too heavy. I've oredered this frame/canopy, excited to swap it over.

Hey, what's your favourite setup now? 4s 450mah & HQ 3x3x3 props?

Sconeboy   Apr 03, 2020 

It's currently a tie between CNHL 450mAh 4s, and GNB 520mAh 4s HV. The HQ 3x3x3 props seem to be perfect with these motors.

Nice build!
I am looking forward to this child's flight video!

Sconeboy   Mar 13, 2020 

Here you go! just a little clip, I need to get the tune really dialed in.

Zin_007   Mar 14, 2020

I like it! Built a similar quad without the vista with same motors but different kv.  I was just complaining that the vista air unit is still too big and then I see this. 😁

It's awfully heavy for a quad this size, but it works!

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..
