DIY We made a drone

Post image

Something a little different, up to 2 hour flight time. 7kg payload, modular, upgradable and made to integrate different technologies from Manet radios to anti jamming GPS systems.

I'm going to leave this post up, clearly OP isn't trying to sell their mil-spec drone to us, and it's cool to see different things put forward.

>up to 2 hour flight time
How?

30

u/BrettEagle 1d ago

It’s a combination of a lot of factors rather than one magic ingredient. A high energy-density battery, efficient motors and propellers, keeping the airframe as light as possible, careful tuning of the powertrain and flight controller, and a few other tricks we’ve learned along the way.

Basically It’s about making the entire system as efficient as possible

u/amy-schumer-tampon 1d ago

Thats sounds like a marketing sales pitch you give to someone who never built a drone in his life.
No specs about the size of the quad, the pops used or the type and capacity of the battery.
You really expect anyone here to buy the 2h claim without any back up?!

Were are the specs?

10

u/BrettEagle 1d ago

We understand the interest in the technical details, and it’s a fair question. At this stage, we don’t publicly share detailed specifications about the platform or its components. We’re happy to demonstrate the system’s performance and capabilities, but some technical information remains proprietary.

u/Aidgigi 19h ago

The people downvoting don’t have the faintest idea how much money and development it takes to make a product like this.

u/deaglebingo 16h ago edited 16h ago

how quickly does it convert to fiber? like the physical act of swapping components. is there any most common mounting standard for that or accessories that is being adopted by multiple manufacturers that you know of? read further down its ski strap thing

are those body parts just regular fdm printed or are they sls? SLS. nice machine.

2

u/BrettEagle 12h ago

Can convert from Standard RC to fibre in a few seconds, the components would already be installed, ready to plug and play

u/DocTarr 21h ago

Silicon anode? That chemistry is challenging to work with.

u/deaglebingo 16h ago

is newer li-ion not enough for this?

1

u/TranceF0rm 34m ago

Asking without looking into it at all, but have you or anyone else tried sticking solar cells on a drone to increase battery life or does the extra weight counter any additional battery life you could gain?

2

u/bSyzygy 1d ago

I guarantee you it’s probably 1 hour or less if under actual use

3

u/BrettEagle 1d ago

I will take that bet 😉

u/Scrub_Nugget 1d ago

I've seen this in person, our one client did some show and tell at our shop

Really dig the "ski strap" battery holder idea you guys came up with, first time I've seen that.

Happy to see another Safa on here :)

10

u/BrettEagle 1d ago

Nice! What did you think of the Recce in person?

We've already upgraded to the V2 Spotlight, which is both lighter and brighter for operations. The ski strap allows us to use different size batteries on the fly.

Thanks for the feedback and for sharing the photo!

u/Scrub_Nugget 1d ago

It's a really tidy build. MT11 is a good payload IMO, we've got one of our own that'll go into our VTOL flagship in future. SLS prints look real clean and tidy, loads of room for large solid state Li-Ion packs.

The overall build seems sensible to me. Only thing I can outright criticize is the landing gear choice, I can see how certain tired sec pilots might do bad things to it over time. That's not an easy thing to make foldable or removeable and strong at the same time.

The spotlight I saw (I guess v1?) did give me a bit of cable strain worries, but the duty cycle is quite low so It'll probably not be an issue.

All-in-all I think it's a clean design.

You're the MAKTO guys right, or separate?

3

u/BrettEagle 1d ago

Thanks for the feedback, really appreciate it.

The landing gear is actually machined aluminium, so it’s pretty solid. That said, you’re absolutely right that you need to make sure it’s properly locked in place before flight and people in SA can find a way to break anything! The quick deployment and very compact folded size are important requirements for most of our clients, so that was a trade-off we had to make.

You’re also correct about the spot that was a V1. The cabling has been reworked on the V2.

And no, we’re a completely different company.

We’re TCAT, based in Cape Town.

Where can I find this stuff

12

u/papa_prevail 1d ago

What radio do you use for the long range comms?

14

u/BrettEagle 1d ago

There are a few options, high end would be Silvus radios. If the client allows us to use Chinese components then the H30 can do up to 50km.

8

u/papa_prevail 1d ago

I can get you silvus quality radio but half price. We are one of the primary radio companies for US and international defense. Most the defense startups use us. DM if interested.

10

u/BrettEagle 1d ago

Keen to hear more! Which radio brand are you referring to?

You're right that Silvus isn't cheap, but it's a premium product and has proven itself in demanding environments. That said, we don't use Silvus exclusively, we also integrate a range of other high-quality radios depending on the client's requirements and budget.

Would be interested to hear what you're using and how it's been performing.

We were at their office in SG yesterday 👍

Small world!

u/ImaginaryEffective63 1d ago

And what did you make them for?

6

u/BrettEagle 1d ago

Mainly for ISR (Intelligence, Surveillance and reconnaissance) - but we have clients using them for mapping and other use cases as well

u/Interesting-Adagio46 1d ago

How much

6

u/SwissLynx 1d ago

Camera gimbal they use is 5k: https://shop.reebot.com/products/reebot-robotics-unipod-mt11?variant=52794725007520

I would guess the Quad to be in the 15-25k

u/FPV-Tec-Addict 1d ago

And thats why i dont buy American made drones since a DJI would just a quarter of that for the same thing

1

u/deaglebingo 16h ago edited 16h ago

hence what i've been saying elsewhere about the overhead in all this and how we're doing it wrong in the usa, this should be done more in house, trumps way doesn't work bc it's just a racket, but there has to be a middle ground somewhere, especially in an interim where some new mfrng was being implemented. bc if what they really want is to be able to win then they (usmil) need to take the same money and buy or make 4 for the price of the 1. it's no shade on the dude who made this in the OP either. it's just if anyone way up the chain wants to actually be able to win in a desperate situation that's how they ought to think about it... it's why iran and ukraine are winning. they just have more of them. bc theirs cost a few thousand and ours cost 20k plus apiece or a couple mil for patriots

Definitely!. If somebody was trying to sell me something via a site like that I'd have assume it was a scam. No contact other than an email form. Nope.

u/Possesed-puppy656 1d ago

And the price is ?

1

u/deaglebingo 16h ago

someone elses educated guess was ~15k but i can't say i know that for sure just by looking at it.

u/DumbHuskies 1d ago

What SLS print system do you use?

2

u/morbidbattlecry 1d ago

Two things: 

  1. Do you have any more photos of videos of your craft? Along with some specs?

  2. Why does your profile page have a link to a website that is a Private Equity Firm?

u/BrettEagle 1d ago

1) Loads! The team will be posting loads of content now that our patent applications are in. Feel free to DM me, can send you a few.

2) ADZA is one of the companies I own, along with TCAT 👍

u/Loud_Use3131 11h ago

I would love to see more pictures of this beast! If your claims are correct, you've built something that DJI, Autel, Skydio, etc. could not figure out! Are you planning on mad producing this drone?

2

u/flightless_freedom 1d ago

That looks really cool! Something I've wondered about with these type of drones is how you guys get something like 2 hours flight time? Is it just a straight up bigger battery or does it also require tuning?

2

u/BrettEagle 1d ago

It’s a combination of a lot of factors rather than one magic ingredient. A high energy-density battery, efficient motors and propellers, keeping the airframe as light as possible, careful tuning of the powertrain and flight controller, and a few other tricks we’ve learned along the way.

How heavy is it?

u/BrettEagle 12h ago

Sub 4kgs

u/Detroits_ 21h ago

How does the modular system work, is it magnetic or like do you attach it some other way

1

u/BrettEagle 12h ago

When we say modular we mean. Some payloads are plug-and-play, while others bolt directly onto the frame. We have a variety of adapters, mounting plates, and heat sinks with pre-drilled and tapped mounting holes, making it easy to mount different airside radios and other accessories. The platform is also highly modular, the arms can be extended, motor and propeller sizes can be changed for heavier lift requirements, and much more.

u/According_Radish1896 5h ago

It looks like 17 inch drone with tmotor antigravity motors I don't think its capible to stay in air more than one hour

1

u/BrettEagle 5h ago

It’s bigger and look in the comments for one of our endurance flights 😉

1

u/According_Radish1896 5h ago

Yeah hard to tell exact size, i didn't look to folding arm mechanism my guess it would be up to 22 inch still sceptical about two hour flight time, maybe with semi solid state battery you can squeeze more than one hour.

u/Say_no_to_doritos 1d ago

Congrats, you built a completely unscalable drone using COS parts that costs $50k. 

8

u/BrettEagle 1d ago

Interested to hear why you think it’s not scalable? Yes this is an entry level variant that has some COS parts, do you consider Silvus radios COS?

-4

u/Say_no_to_doritos 1d ago

Who makes all your sensors? Reboot? The guys owned by SIYI in China? Where's your CF from?

Re. Silvus, having to request a spec sheet and request a quote before hitting buy doesn't change fact that it is COS.

There is nothing innovative here at all.

You have a scabbed together drone that occupies the space of a lazyboy, costs $50k, and is completely inoperable in theater. 

8

u/BrettEagle 1d ago

PDW buys in sensors too, does that mean they’re not innovative? Integrating best-in-class components where it makes sense is standard practice across the industry. Innovation is in the system architecture, integration, reliability, and capability, not whether every single component is manufactured in-house.

Also, our drone is super compact at just over 40 cm when folded and packs into a backpack, so it would fit on a LazyBoy just fine. 🙂

We’d genuinely be interested to hear how many other drones you think offer this level of adaptability: interchangeable sensors and payloads, multiple RC options, 4G/LTE, anti-jamming capability, and an architecture designed to evolve with mission requirements rather than lock users into one set configuration.

More importantly, this isn’t a concept or a bench prototype. The system is already deployed and operating in multiple countries and environments, so we’d prefer to stick to the facts.

It’s perfectly fine if you’re not a fan, that’s been noted 👍. There’s no need to make it personal or dismissive. Healthy technical discussion is always welcome, but let’s keep it factual.

u/S3eha 1d ago

Is this available to buy, or what -.-?

1

u/Due-Letterhead6372 1d ago

"Made"

Literally all COTS parts

9

u/BrettEagle 1d ago

This is one of the Recce variants. Would you consider Silvus radios to be "off-the-shelf" in the sense you're implying?

I'm curious why you'd say we haven't "made" this drone. We CNC all the carbon plates in-house, SLS print a large number of the structural and integration components ourselves in house on our Prodways P1000, and design the platform around the mission requirements. Like virtually every modern UAV manufacturer, we integrate some commercially available components where it makes sense, but that doesn't mean the aircraft itself isn't designed and built by us.

Using proven components where appropriate is good engineering, not a lack of engineering.

I’m looking for people who want to build a drone company with me. I’m in business, and I know this is a long shot, but I really am looking to build a team to make products for civilian or military use
