The goals:
You may notice the motors are staggered due to the spar layout. I haven't noticed any issues with this.
It needs just a little more beef to it - or does it? There was some jello in the video, but it looks like a little more tuning might take care of it.
I only flew it once so far and ended up with a 8:17 fly time (interrupted by a small crash/fall from a tree). Due to my inexperience with lightweights, I'm not so sure this is a good time(?) Also, I was taking it easy:

OK... I think I have a valid question that I might as well ask in full public view so we can all get an education. How do you land a pusher? If it is "the same way you land your ARX-R"... do you tear the props up a lot on landings? I have seen that guy on YouTube hand-launch and land, but I can't do that... lol.
Also: Have you flown one of these ultra light ARX's with APC's?
Hmmm. Yeah. I myself do not fly LOS outside of 2". That... would be a challenge for me. Do you land all of your frames like that? How does the speed canopy stand up to landing like that? I actually pull back and float 'em down. Sometimes I gotta circle for another attempt.... doesn't bother me.
Also: Just watched that printed pusher maiden vid on the 'tube. We wanna see the quad pics (and maybe fly it a few packs... lol. =])! I wanna be the first kid on my block to have a 3D printed ARX variant
Here is what I do. Option 1 when you come in for a landing start making very very tight Spirals and kill the quad about a foot off the ground. Just take some time again practice so that you don't kill the quad too high up. Option 2 would be land near a six to ten foot pole and use that to guide yourself in again kill the quad right before you land on the ground. Basically at 45Deg Cam angle you will just see the tip of a pole in the bottom of your view and that will let you know you are level then get your hight sorted out keeping the pole in view so you do not drift too much.
Pushing the limits again! Good work man, this is impressive.
3D printed frames are so much fun to design! Super cheap, fast prototyping cycles plus more degrees of freedom.
Also they are easy to share with the community. Super curious what you will come up with!
Let me know if I can help you out I've learned quite a lot playing around with 3D printed frames in the last year!
I have been watching your development on this since your first post, and it has been a wild ride. I remember your first tube with panty hose egg sized nose cone, and z arms. It was so far from what I saw everywhere else, and yet so obvious. The different construction techniques you have implemented, gained skill in, and eventually moved on from, have been so interesting to watch. The current superlight approach is interesting, and this is a good time (in terms of available, off the shelf PCBs) to be doing it. I wonder if you will soon be able to get 16x16 stacks that can handle 2204 or 2205 motors. I'm suprised you don't have a canopy of some sort on this though, have you considered vacuforming polycarbonate?
very sad there wouldnt come evolutions with carbon from you :-( sad sell your beautifull frame doesnt support your pioneer work enough.
very nice there will come some prints. can we have look at the test print process :-) are there allready templates :-)
i have got a question about the arx design, are there some downsides mount the fc vertical?
i tought about a quaddesign where the battery is in the middle of the frame and on onside vertical mounted is the fc on the otherside is the esc. i like to try this on a nanoquad, or im not sure... im sure you mention about this option or know why not to mention about, if you could explain would be very nice.

looks awsome!. the fact that you can fly around at ~5A is amazing. my 5" hovers at 8A lol. Your frame design is always so interesting, keep it up.
I think there's actually a point from where the 5" is becoming too light. Especially if you fly on a windy day. Perhaps make it 4 inch to reduce its sail area, use some 2204 motors with a higher kv and it will likely be more enjoyable overall. 2204 for a 5inch is too weak in my opinion. It can't accelerate the props well enough.
Oooooh. 2204.5 Hyperlites are killer. I just got a set and put them on an ARS 3D print job with a Mamba MK2 20MM. It is really gonna be hyper LITE! I'm mocking it up at: https://rotorbuilds.com/build/18617
Edit: lol. I just saw that I also just used the exact same stack you did for this on that ARS-5 (my first Mamba anything...)! Dont you think that they could have made it just a little easier to solder? They really pack a lot of wiring into such a little stack. Still... it is powerful, full featured, lite, and it is CHEAP.
why is the weight overrated, because of physical limitations which go more worse with less weight? (regardless of windy air)
is it simply because we can choose very enough powerfull motors? because benefits arent usable softwaresupportside?
my toughts was the marketsupport, like lightweight 5" props... or probably the software are the limitations.
My guy strikes again, lol, that looks really efficient, light weight, low power motors and good aero arms, with a battery of that size, that's definitely a good flight time. how do you reckon it'll handle a crash or fly with a larger pack (wont be sub 250g but still)?
I had a fairly low impact crash in the video (stuck in tree, then fell) and it was fine but not a good test. With the battery on, I chucked it around the living room a bit and made sure it landed on the arms. The worst that happened was the motors sliding about 10mm on the arms which is by design (no hard mounting locators). I get tons of flak for the way I mount motors but I'd much rather loosen the motor screws to realign the motors than break something. I worry more about the vulnerable fc and camera than anything else.
AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

Oh hey man! See how the plate is on this build (no hooks for the bands and larger slots)? That is what I was saying about doing to the normal ARX-R plate.
