Pixhawk Stability

I have a 750 drone I’d like to use one of the PX4 FC with and was wondering if anyone has any experience with?

Rick

Do you mean Pixhawk4? It seems lots of people use them and it’s fully supported with Ardupilot. Chech the docs for supported hardware.
PX4 is actually “that other” autopilot software, ie: Ardupilot vs PX4

No Shawn. I mean the 3DR version, which the website seems to be dedicated to. The Pixhawk 4 has a completely different website with input for their open source project. Completely different camp. I’m looking for actual flyers with experience and knowledge of the products I ask about, but thanx anyway.

There is no more a 3DR version… https://docs.px4.io/v1.9.0/en/flight_controller/pixhawk.html

The latest hardware:

https://pixhawk.org/#autopilots

It’s amazing this website has all the documentation for that model and, as far as I can tell, nothing on the Pixhawk 4. I’m using an older PX4 FC and am looking for someone with experience using these in a larger drone.

I haven’t used a PX4 FC myself, but the hardware is still supported. It’s called “fmuv1”
As such, I see no reason it wouldn’t fly a copter, regardless of its size. You just have the 1MB limit, so some advanced features like crop sprayer won’t fit.

It would be really nice is you would post a link to the web site you keep referring to.

Read this from https://px4.io/ :

" What Is PX4?
PX4 is an open source flight control software for drones and other unmanned vehicles. The project provides a flexible set of tools for drone developers to share technologies to create tailored solutions for drone applications. PX4 provides a standard to deliver drone hardware support and software stack, allowing an ecosystem to build and maintain hardware and software in a scalable way. "

What is Pixhawk

Pixhawk is an independent open-hardware project that aims to provide the standard for readily-available, hiqh-quality and low-cost autopilot hardware designs for the academic, hobby and developer communities. Pixhawk supports multiple flight stacks: PX4 ® and ArduPilot ®.

You are confusing the Pixhawk FLIGHT CONTROLLER HARDWARE with the PX4 and ArduPilot AUTOPILOT COMPUTER CODE FIRMWARE.

So, your real question should be about which version of PIXHAWK hardware should you be using.

This one. https://discuss.ardupilot.org/. That’s how I got on this forum. The docs refer to the 3DR FC. It’s well documented too. I shouldn’t have any trouble. LOL.

I guy walks into a brick and mortar hobby shop and asks for a Genuine 3DR Pixhawk.
The shop owner tells the customer, “I’m sorry Sir, but genuine 3DR Pixhawks have been out of production for quite a long time and 3DR is no longer in business.” The customer turns and walks out.

For the next three days this same customer comes back at the same time, asks the same question, the store owner gives him the same answer and he walks out.

On the fourth day the customer comes in again and asks for a Genuine 3DR Pixhawk. This time the store owner says, “Let me ask you a question: How may F’s are there in Genuine 3DR Pixhawks ?” The customer replies, “Shoot, there aren’t any F’s in Genuine 3DR Pixhawks.” The owner responds, “That’s exactly what I’ve been tellin’ you for the last three days, There ain’t no F’n Genuine 3DR Pixhawks.”

That’s funny. When I walked into a brick and motat hobby shop and asked for some wire, the guy told me to go online and get it. Then tried to sell me a $7 servo wire.

I’m not using a genuine 3DR box. It’s one of the thousands of clones out there. I bought it from a reputable company. It came with a money back guarantee if it fails.

@rjriggins111

mRobotics Pixhawks are as close to OEM as you can get. It has a different logo and some minor upgrades. The company was started and is run by one of the original 3DR founders, many of the testing jigs, molds and staff members migrated over. Sadly with the obsolesce of sensors this board will not be available forever.

There’s a website for that Introduction · PX4 User Guide.

I’ve done a little research and this is recommended as a drop in replacement. I bought one of the drop in clones though. I bought it from a reliable vendor. It came with a money back guarantee if it fails. I hope I don’t post run-away results.

Rick

I’m starting to smell a troll. Notice how some of the story has changed, yet there are no vendor names or any SPECIFIC links to anything of relevance?

A very good clone is pixhawk from Radionlink. I have some of them and never had problem. They also do not have the 1MB limitation.

I’m not sure what you’re getting at, but thanks for the response. Goodbye.
