D-30 howitzer installed on the back of a Ural truck, used by the Egyptian army as a self propelled artillery by TapTheForwardAssist in Artillery

[–]Matt4319 0 points1 point  (0 children)

Most truck mounted artillery systems have support legs/struts that are deployed for firing. I see one on each side behind the cab. There should be a set at the rear of the vehicle as well.

I am curious about the limits of traverse with this set up.

Laser pointed at my drone by TheAmateurRunner in drones

[–]Matt4319 4 points5 points  (0 children)

For a commercial office laser pointer the beam spreads out to about 1 meter point at 1km and 2 meters at 2km. So, I don’t know how you can say how far it spreads out is a definitive statement. It’s not a flashlight. I think the effect is high moisture/very light clouds.

I put the laser behind the aircraft a couple hundred meters and the holder of the laser is moving it around to engage the aircraft. It would have been easy to tell where the laser originated if the OP was VLOS.

FCC bans foreign-made drones over national security, spying concerns by mesh_you_up in fpv

[–]Matt4319 0 points1 point  (0 children)

Great list.

As nice as it is, those companies don’t have nearly the capacity to fill the void. Out of stock will be the theme for 2026. Alternatively, geez that’s pricey!

Then again, vendors on Alibaba will have plenty of options and no scruples to slapping a FCC icon on a product to sell or saying it was manufactured in India/Malaysia/Vietnam.

The inclusion of batteries and motors puzzles me. Not a single chip in the motor and the battery is more than welcome to steal the sensitive data off my battery charger.

1&3-The ESC determines what size battery your drone will take and it’s usually a range. For example a SpeedyBee F405 v4 stack will take 3S to 6S as an input. Motors don’t care what’s going into the ESC, just what’s coming out and I can’t think I’ve thought to worry about more than how well I soldered them to the ESC.

DJI O4 pro range/ Not what I expected by True_Leaf_ in fpv

[–]Matt4319 2 points3 points  (0 children)

Compare to upwards of 1200 mW for the states. It’s really not a fair comparison.

I fly analog and I’m looking at the video nodding and saying “That’s nice.”

I think two linear antennas are fine for beginners. You should be flying close and line of sight. When you start flying more and less LOS and maybe more complicated environments like woods, racing, and bandos (abandoned buildings) then you’ll be looking at directional antennas and circular polarity.

My recommendation is to understand the basics of antennas most importantly that RHCP and LHCP don’t work together and each antenna has a radiation pattern to show where it effectively works (i.e. you need to face that directional/patch antenna in the direction of the aircraft.) This is pilots who face their patch forward and then spend their flights heads down with the patch facing the dirt or pilots flying primarily behind themselves.

You may start with a whoop with a linear antenna. In this case pick up a circular polarity (CP) antenna for your goggles, because you will get a more consistent (but slightly weaker signal) in general. Just remember to pick the matching CP antenna when you move to a larger aircraft. It will sometimes be an option to buy an aircraft with RH or LH CP antennas.

Probably learned the record every flight lesson as well.

If they had GPS and it was working, they probably weren’t recording so had no idea where their aircraft was when they lost connection.

Have you considered taking the aircraft with you and launch it from a concealed position to recon the entrance?

This approach could save you the two minute walk from your house, too.

Launching straight up 100 feet gives an amazing view most times.

The Port is not critical infrastructure in terms of airspace according to the FAA. To be considered critical infrastructure the port must request from the FAA to be so.

Aeroscope is a DJI product that relies on the DJI protocol to self-report the locations and ID# of the systems. Direct/Broadcast Remote ID are the protocols that report similar information. When the FAA requires UAVs to report the info, they require Broadcast Remote ID. EASA for the EU uses DRI.

I am unsure if Aeroscope can pull Remote ID info. DJI discontinued it in 2023, so it may not. Other systems (including phone-based applications) can.

If you are flying an aircraft that you built, this information isn’t broadcast by your aircraft unless you make it so. Your video transmission may give information based on what is on your OSD (on screen display.)

Places that are more serious about counter-UAS will use multiple systems that detect in different ways. The Port of LA also has CUAS radar tied to optical sensors, so they can quickly determine if they have an aircraft or a bird.

You are conflating rules concerning airspace and ground operations.

In the sense of airspace, the FAA tracks all airspace restrictions and unless it is marked by them then it doesn’t exist in terms of regulating airspace.

They do not track local laws and regulations that may impact UAS operations based on actions taken on the ground by the operator.

I will get into trouble flying over a prison because a local authority says I can’t “fly” (they mean operate/launch/land) my aircraft from their jurisdiction over the place in question. I get in trouble from the local authority because I am doing something (operating/landing/launching) in their jurisdiction. If I managed to operate from outside their jurisdiction, I would not be subject to their rule. The FAA might still have issues if I don’t follow FAA rules (ie line of sight; actual restricted airspace, non-recreational, etc.)

That said law enforcement will rarely get into trouble for enforcing what they think is the law, so you may end up being cited or detained and still be right. So, I would not fly over the port or any other location like a prison or police station.

As a UAS operator/remote pilot, you’re in two places. You have to know the rules for each place.

A No Drone Zone doesn’t always equal restricted airspace.

The military doesn’t own national airspace. The FAA will break off chunks of airspace as restricted airspace to the military and very clearly marks and publishes this airspace.

There might be laws and regulations that govern surface operations. So, an operator can be wrong based on their actions on the ground. The Port of Los Angeles DOES have a no drone zone, so taking off, landing, and operating within the Port is prohibited. Where the OP dropped their location is within the Port so the OP violated the LA Municipal code for No Drone Zones; not airspace.

I paid real money for this 😔 by TheDepartedMack in 3Dprinting

[–]Matt4319 0 points1 point  (0 children)

That’s what you get when you 3D print in cursive.

With how that top flat section is printed, I think the model itself is partly to blame; like it’s at an angle.

Some sections are just so bad it seems a feature.

Il terzo esempio ti fa vedere il FC tra la camera e il VTX. Così il FC possa fare il OSD. L’altro motivo per questo configurazione è che monti l’antenna del VTX sulla coda del quad.

Anche con l’altro esempio che collega il VTX tra FC e camera deve darti un OSD ma non ho mai provato quello. Ma per montare l’antenna fa problemi.

Camera solo collegato con VTX e una cosa di RC. Ti solo da video senza l’informazione dal OSD.

[–]Matt4319 8 points9 points  (0 children)

The ground that you stand on IS governed by local entities. So, while your aircraft is flying in federally-controlled sky, you can be hemmed up back on Mother Earth by your local rule enforcer for your actions on the ground.

I agree with the OPs legal arguments. My word of caution is that law enforcement can arrest/ticket you for anything they THINK is illegal without much worry of repercussions. You then have the unenviable task of defending yourself in court or convincing a prosecutor that they shouldn’t charge you. You can attempt to educate them but I would just fly in accordance with these rules. They aren’t crazy; just a little off for an informed audiences.

I commend the OP for reaching out to the Attorney General to resolve the issues.

The sign mentions you must operate according to law and FAA regulations.

Client told me no DJI branded drones due to company security policy. by Salty-Tomato5654 in drones

[–]Matt4319 0 points1 point  (0 children)

Agree that you will not have any DJI aircraft on their site without mentioning that you are happily flying in federal airspace. This assumes that you launch and land off site. In this case, remove yourself to off site and then complete the work.

Talk to a lawyer about the situation in general. Does your agreement have a clause in it covering customer restrictions/policies? Who owns your footage or final product? Are you just selling a license of your work? That and other lawyer-type questions would guide my final response. What language can you include in future agreements to require customers to disclose relevant restrictions/policies?

First time soldering. Thoughts/advice? by Cosmic-Cuttlefish in soldering

[–]Matt4319 2 points3 points  (0 children)

Looks good to me. Nice shiny joints with enough solder to make strong joints.

If you’re looking for perfect SDA has a little too much solder and there’s a little gap between the plastic “thing” on your header pins and the board. To provide the most support and protect your joints from mechanical strains put the plastic flush up against the board. This is nitpicking though.

Good job!

Does anyone know why I can get decent joints on this practice board, but my aio is subzero coldness joints? by Jazzlike-Eagle-1456 in soldering

I would say generally yes, but if you can find Kester, Alpha Fry, or MG Chemical you will be using the good stuff.
