This is mostly used parts from other quads stuck in a new frame. I'd definitely pick different parts for a new build, as this was a bit tight getting everything together.

She is a bit goofy looking.

Need to figure out a better antenna mounting solution.

Have you noticed any advantage of the Z frame configuration? Hope it flies well, I'll building mine tomorow.

Think it will hold up to crashes with 1407s? Its much lighter than any other 4 inch frames I know of. I wish there was an option for the 3d printed canopy to extend further to protect the camera

Looks amazing! 139mm with 4 inch props? Thats insane. It looks like that could be setup pretty light if you wanted to. Just wondering though, Is there anything supporting the stack in a crash? Does is have alluminum standoffs too? Or just the standoffs in the stack? I'd be worried itd snap right in the middle.

Yeah, they're all 3" with the zeus. I heard that the Zeus didn't immediately explode and die on 5S though, so that is interesting.

Quadlite   Jun 18, 2018 

that is interesting, kinda like the babyhawk r running 4s on a 12amp 4in1 esc. its always made me nervous but it seems to work fine. motor and prop combinations will obviously matter too. None of those 6 blade racecraft props or itll bloe for sure lol. even gemfan flash 3052x3 draw a lot of amps.

So i was looking into this frame and it looks like the production version is actually a little over 160mm. Thats how it fits 4 inch props. Only the prototype was 139mm and that one is for 3 inch props. I was wondering how that was possible. 139mm with 4 inch props seemed very odd. I think 145mm is the bare minumum that ive seen for 4 inch props. Most 4 inch quads are 160-180

BloodyLordV   Jun 16, 2018  

Does RotorX Switchback natively support 4 inches?

Yeah. I was actually building it thinking that it was 3" only but I had a 4" prop on my bench and I stuck it on there.

Thanks! Do you have any filght vids?

Your capacitor sticker makes the drone.

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..
