Airborne Aircraft Carrier - Testing the FB Limits.

[LitterBug]

Those Eachine E010 are essentially 4 brushed linear ESC with a gyro and some processing.
I was trying to figure out how to transform them to a version that creates an inexpensive parasite fighter. $15 vs $100

Yeah, you need to find the seial port pins, find out what firmware is on them, and then modify them to react the way you want.... I'm guessing old f1 processors, palusible f3. I have old whoop stuff coming out of my eyeballs which is why I picked up the brushed escs.

Actually, looks like they have a USB pinout available. VDD, GND, CLK, DAT

So… where do I learn more about understanding this board. I once dove deep into the depths of RC groups to learn something… I learn likely no. But I am of for reprogramming the boards to work as a stabilizer and like a 4-motored EZ system but horizontal.

 

[LitterBug]

Working with a lot of unknowns. It's plausible, but probably going to be time consuming. That's why I have started going down the more traditional road with the tiny motors, escs, and servos.
Frrom the pictures I found, The CPU is the bigger of the two chips and the gyro is the smaller. The numbers on the CPU don't mean much to me.

I will admit this post is mostly for myself, but you may also find it useful and interesting.
FYI - There is a brushed version of the MonoPhan quadwing project. Perfect for the eachine E01# quads. The GitHub link has the stl files and plan image to print cut from DTFB.

If I tackle much of what I am looking to do on this project, (and my full scale) I am going to need to educate myself on this topic - the Wiring harness

Now that I have function 3D printer again… it’s time to dream. (Pogo-pin and rare earth magnet) based FPV cam bases.

 

[FoamyDM]

As I build the Quadwing, I am noting, 2 critical things. Motor wiring. Placement, and the Board Angle. Hench the little rec platform in the build.

OK, Here is the assembly Video:

Divising the launch mechanism

There are 3 that i keep seeing.
The first and best option i see is like a Motorized nerf gun (motorize wheels). Here is an example:

Then there is this is one:

The last one is a variant with a rotating geared cylinder launched with elastics

Have you seen the brushed differential thrust builds @Silver Surfer FPV has been building and flying in his thread?

1s Differential Thrust Builds

Thumbs Up Parts used - Z51 Predator receiver (TX16S Protocol KF606) - 8520 Coreless Brushed Motor - Dollar Tree foam or Depron - 1s Lipo 400mah

Yes! I love them.

i haven’t seen much about his power systems. It looks like he is using a micro dsmx/dsm2 board. (I have a few) Most of those micro control boards with brushed ESCs tend toward $40-50, some pf them are similar to the FT-EZ STEM boards, but flat. if i am to have 4-8 passengers at the ready for launch i need to keep investment on the parasites low, of make them from parts people have at FF. (Its why EZ boards are a key design criteria)
It scoots well past my budget. Most small quads are $85+

Is there a design he had that might be fun?
(Maybe a micro ft-rocket) 🤭

after falling down a rc groups rabbit hole... the Z51 board from the Banggood Micro predator drone (like the EZ board, but the board is Flat) The board is ~$3! It is out of stock. I can swallow that price though, especially as it looks like it can be a horizontal direct replacement of the FT-EZ board.

It is clear the E010 board or motors i resoldered, aren't correct. (trying to figure why)

Looks serial to me, but im a geezer and there's not a big difference between the two except maybe clock rate

 

[FoamyDM]

I think i got it. 😅
I flipped the front and back wire sets. If it works i will have to check thrust, to see which gets the best bang for the buck.

Not the shining success i was hoping for, but not without promise.

Did you try it without the wind? When you threw it directly into the wind, it looked very controllable, but lacked the necessary thrust to move forward.

The EZ has the same problem with/without the wind. Do you know if the 1S battery could be changed to a 2S system and not fry the board or motors? No one seems to know the answer. I tried launching my wing off 2 stiff wires(horizontal, polished and oiled where FW had straws glued to underwing) full throttle and no movement.
Then flicked TE with finger(4 tries) and I was successful once where I throttle back to 1/2 and then brought it around and landed.

Maybe a shuttle type of launch might work for your system? With the FW inclined at a small angle and carrier moving, it could lift the wing and full throttle, it climbs away. Might only work with no wind!!!

Not yet. The side to side oscillations were a bit much. I will let you know how a light wind flight goes.

2S does fry it, as I understand the component are rated upto ~5V. components tend to go after that. the E010 and E017s have 0615 motors. with TINY props (30mm). I imagine, an 0820 or 0825 motor set would give it some extra umph, if the extra AMPs doesn't fry the circuits too.
It was weird, the Throttle seemed to top out at just above mid, unless I added directionals, then it would boost those motors in need.

I know the EZ-V2 can run bigger motors and Props. Just trying to see what are my effective inexpensive options.

It's good to see you back. You are always exploring to push the limits.

that wind (at least what it looks like from the grass in the foreground) looks like a bit much for that craft
also... can we get the music slightly louder - we could almost understand you

I just get dumb ideas in my head, and just have to get them out.

I will try for louder next time J. I appreciate the feed back. Ooh, while you're here. do you have a good link to a mulit-channel FPV feed system? DIY doesn't scare me.

Are you talking about viewing multiple feeds on 1 monitor or having multiple cameras that you can switch between on the craft or something else?

if your talking about multiple feeds on 1 monitor, your probably looking for something like this: https://www.amazon.com/dp/B081CK69CH/?tag=lstir-20 [I speak nothing about the quality or validation of that specific item, just looks like it does the needed stuff] and multiple FPV receivers - one tuned to each channel you want to be in your feed. a how to page: https://blog.seidel-philipp.de/diy-fpv-splitscreen-for-racing-events/

if your talking about camera switching, your probably looking for something like this: https://www.amazon.com/dp/B0CVG55P2M/?tag=lstir-20 but I will warn you, some RX systems that do dual RX behavior to help reduce noise don't like those as they don't sync the 2 cameras - and can have issues ... I don't know of any good setups that solve that [have only seen it on _expensive_ media systems for live broadcast mixing where a sync is sent out from the mixer so that all the cameras are running in exact time sync with each other]
