Sale can happen directly on this board and need not happen via ebay. venmo and paypal accepted. You pay shipping.

Y6 Drone Custom DIY build. Condition is Used.

The drone copter was flown for maybe 30 minutes total. Barely used. It does need some work before it can fly again as some parts came loose. All the parts to make this thing fly are here. I don’t have time for this toy. There is well over $1000 in new parts here. Currently the copter is configured as a Y6 with coaxial motors on the 3 chassis arms.

3DR Y6 foldable frame (carbon fiber), can be configured as a hex.

6 x 810 kv brushless outrunner motors

6 x 1055 carbon fiber “t-style” props

6 x 20 amp ESC

2 x 5800 mAh 4S batteries

1 x 9ch Turnigy tranmitter

1 x 2-axis brushless gimbal

1 x APM 2.5 flight controller w/Ublox gps and sonar

1 x 915 Mhz telemetry

1 x power module

1 x 3S lipo battery (for brushless gimbal)

1 x Charger

1 x Power supply (for charger)

Dodeca Hexa – only 10 of 12 Motors get a Signal

This is a re-post of Dodeca Hexa with “Flier OPTO ESC” – AUX Output Channels are not working correctly

It seems like that the interest on a Dodeca Hexa Frame with a specific Flier ESC is very low.
But I am still sitting with the problem. This is why I try it with this new post.

In this post I will concentrate only on the main problem: “only 10 of 12 Motors get a Signal”
(the wrong motor number allocations I can change in the settings. Not the right way, but it works)

I organized an oscilloscope to be able get some facts:

On 10 of 12 outputs of my flight controller (Cube 2.1) I am getting a perfect signal:

These motors are also working as expected if I perform a motor test

On 2 outputs I get no signal at all:

image

I tried all scenarios: motor test, armed and live…
(with connecting a servo tester instead of the FC connections: it works!)

It could be a software problem (which I believe) or a hardware problem. But I really have no idea how to find it out and how to go ahead. I need assistance in any case: Hardware or software…

Important note: These signals (the good ones and the bad ones) I am getting in all test environments: Disarmed, armed and motor test. It really can’t be a wiring problem, because if I am using a servo tester, the 2 problem motors/ESC’s are working perfectly.

I hope to get with this post some more attention and hopefully somebody have an idea what could be wrong. I strongly believe in a firmware problem. How can I bring this to the attention to a developer?

Thanks in advance

Peter

RC Override in Mavlink

@charles_linquist wrote:

I apologize if this has been answered elsewhere, but … If I have an RC radio connected and issue the MAVLINK command RC Override followed by values (ex. 1500 1500 1500 1500), does this prevent any more input from the R/C radio and “lock” the values of the first 4 channels to 1500?

As a test, I issued the over-ride command (via Mavlink) to the FC, and it didn’t seem to affect the R/C input “sliders” when I view them in the Initial Setup screen of MP.

Am I wrong in how it works, or did I possibly issue the command incorrectly? Or something else?

Using Main Output Servo

@Preamble wrote:

Working towards migration to Blheli_32 and DShot protocols which looks good so far, minus any test flight. This is a HEX build and I have motors on AUX ports, BRD_PWM_COUNT - 6
My question, if this setup is successful, I will still need a SERVO channel for Gripper in the near future.
If using 6 AUX ports for motors, am I able to use MAIN output port for SERVO?

If so, I’m trying to get my head around configuring the channel mapping…

If not, I guess I’ll have to move motors back to MAIN output and use OneShot…

Thoughts?

Hello,

Okay. Back to reality!

I found a BHeli Configurator application online. It is an Open Source calibration tool/app for updating and changing things w/ firmware on the ESCs. Nice…right?

P.S. Well, is it possible to use the BBBlue instead of the Arduino for calibration of my ESCs?

I’m doing a land command in a mission to a lower than launch surface.
The quad climbs to 0 Altitude before descending and landing.

Launching at height 0
Moving to a way point at -20 meters below launch.
Issuing land command, the copter climbs to 0 and then starts descending to land.

Is this behavior configurable?

Scorpion esc beeps using pixhawk 4

Hello dear arduplane users,
I’m using:

  • pixhawk 4 with arduplane V3.9.8 (latest)
  • mission planner 1.3.66
  • ESC and motor are both by Scorpion.

I connect “FMU PWM IN” from pdb (power distribution board) to “I/O PWM OUT” of pixhawk, and the ESC to channel 3 of FMU PWM-OUT (and the servos to channels 1 and 2).
When connecting the ESC directly to the channel 3 receiver it works absolutely fine, but when connecting as described above the esc beeps continuously and wont rotate the motor (while the servos work fine). I checked the pdb output with oscilloscope and it outputs a perfect pwm- when throttle on minimum 1 mSec pulse width on 50 Hz cycle(3.3 Volt).
I tried 3 identical ESC scorpions and 2 scorpion motors and 2 pixhawk 4 controllers (with the same settings) and the problem appears on all of them.
I double checked the connections and they are correct (the polarity of pwm) and I even checked the connection with a DMM.
The funny thing is that it worked before at the same configuration and than suddenly stopped.
The mission planner depicts that everything is OK and the plane is armed.
I’m quiet lost with this problem…
Thank’s in advance!

Hi,
I´m trying to set up a fish feeding boat for fishing. Everything seems to work, but i can´t set up servo functions in the servo tab. For every function it just says diabled and can´t be changed. Any idea what i´m doing wrong?
I also can´t set it to boat mode.
This is my first time using ardupilot, so its probably just a dumb mistake.

Hi, I am using a L1 base station (M8P) and stream the RTCM messages 1074/1084/1094.

When I inject these in Mission Planner, GPS and GLONASS are recognized but Galileo is not.

The in comparison RTKlib software recognizes the Galileo messages and shows the satellites.

Do I need to configure something?

How do you activate a rangefinder for Copter landing?

@flyingw wrote:

I’ve used my TFmini rangefinder successfully for ArudPlane landings.

I want to use it for copter landings.

How do you configure ArduCopter so that it uses the rangefinder instead of the barometer for the final landing?

I’ve set:

RNGFND_MAX_CM = 300 cm

Will the copter use the rangefinder below 300 cm?

Thanks,

Paul

How to configure a contact sensor in ArduCopter?

@flyingw wrote:

Because I have had difficulties in having the motor turn off on landing with my SingleCopter, I want to make a simple contact switch and put it on the bottom of one of the landing gear legs.

When the machine touches down, the switch makes contact and the signal tells the auotpilot to turn off the motor.

Does Arducopter with a Pixracer have this kind of capability? Maybe use the safety switch?

Thanks,

Paul

Hi,
I want to make my X8 a VTOL plane.
i have seen this post and i plan on doing the same but i would like to maximize my flight time and my effiency.

i’m using Scorpion 4020 540KV as the main motor and Scorpion 110A as the ESC and pixhawk 4.

What motors should i choose?
What length should the extensions be at?
is the pixhawk 4 better then the pixhawk 2.1 cube (in general and for that specific purpose)?

any tip would be appreciated!

Compass Variance Issues

@thatsnailguy wrote:

@tridge If you have a spare cycle, I would very much appreciate if you could look at my logs and suggest something. - I know that you have worked out compass offsets manually from logs before. If you could point me in the right direction to learn this power I would be very grateful.

I am having Compass toilet bowl problems in auto mixed modes. As well as compass variance error messages. I have tried doing motor/compass interference cal and it doesnt seem to help. I can induce a compass variance error message by increasing throttle.

Due to a design intent, I cannot move the compass farther away from the voltage sources. Is there any hope for this multirotor?

Is learn offsets in flight enabled yet? If not, is there a beta compiled firmware for cube black I can try?

Thanks for any help anyone can provide.

Restarting/resetting a mission during SITL session

Hi,

I’m wondering what’s the best way of restarting/resetting a mission during a SITL session. I don’t seem to be able to reset ArduPlane to the state it was in just prior to takeoff. I need to find the quickest way of doing this because I’m going to be doing it a great deal. I’ve tried setting the current waypoint to waypoint 0 but this doesn’t seem to work - and I’m not even sure this is what I ought to be doing.

Any advice would be gratefully accepted.

Thanks.

Hi,

Anyone has tried this 5/6" frame with Arducopter yet ?

ARX-R V2 frame is the fastest 5"/6" class quadcopter currently on the market.

It is a beautiful piece of engineering that has been developed by Ryan at https://quadstardrones.com/ Flight videos of Ryan here : https://www.youtube.com/watch?v=T_NXj… The kit provides an option to assemble a 6" true X quadcopter or a hybrid 5"/6".

Battery failsafe worked properly around 21.3 with Loiter mode on last Saturday(log seems to be deleted), and the drone finished the mission properly with exactly same setup as you can see with the first log. But battery failsafe didn’t trigger at all, and resulted in a controlled crash-landing onto a bush in the second flight.

Is it possible that the Pixhawk prioritises MISSION over FAILSAFE? Or can there be other reasons of this crash? Thanks very much for attention and time in advance.

Unfortunately, I’ve just found out that the Copter stops far too aggressive when flying in Loiter mode and switch into Land mode. This has already been fixed in version 3.6.7 under NuttX. Was this forgotten when switching to chibiOS?

@rmackay9 - Please look at this picture or the log file to confirm. This is very dangerous for a big autonomous flying drone. PLEASE, it would be nice if this works properly again in the next version.
Thank you in advance!
