Catalyst Machineworks SlamNasty HD

This is all @M490fpv 's fault. So I decided to see whether I too could get a DJI FPV System Air Unit into the SlamNasty 5" frame. And, after a good deal of time in TinkerCAD, and printing a not insignificant number of versions of things, I have indeed got a hovering, HD-transmitting quad squeezed into the SlamNasty. I'll have to wait until next weekend to see if it really flies though, but early signs are positive.

It was an interesting challenge that seems to have worked out quite well. It's a compact little ball of potential energy, and definitely a good looking frame, even though it is now oddly bloated with HD kit. I have hopes...


UPDATE 2019-10-17
I got to sneak out first thing before work and put a couple of packs through this build. And apparently it flies fairly well, although I was still tired, and this is an unfamiliar machine, so I wasn't trying too hard. But all the same, I am pretty sure this is working out just fine.

Now that you've had it a good while. Any tweaks/changes you would make? I'm getting the same frame with dji and was going to run the brother hobby avenger 2806.5 1300kv

So no, not really, this is perhaps the best of the HD builds I have done, it flies really well and with an agressive precision. I did print new rear standoff covers that have little lugs that keep the Air Unit MMCX connectors pressed in (see the last photo), which was a good idea, but othere than that, this has worked out really well.

As for 2806 motors, I think those might be a little bit too much, although I have only recently graduated from 4S to 5S so maybe these would be OK with 6S? But usually motors that big are intended for 6" or 7" props on mid-to-long range machines, not 5" racers. Personally I would stick to 2306 or thereabouts, but as I say, I'm not a 6S flyer so I may not know what I am talking about here (which is very often the case).

And as for the various TPU bits and pieces, I posted them to Thingiverse, you can find them here: https://www.thingiverse.com/thing:3919933, If nothing else, you can use them as a basis for your own parts!

Thank you! I cannot deny that it came out better than I had hoped. Flies like a demon too.

Thank you! And yes, do it! With a bit of effort you can get this DJI kit into a surprising range of frames.

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
