I have a DJI A2 GPS Pro Plus unit for sale! This is just the GPS unit. The FC on my A2 system crapped out on me so I'm parting out the other bits. I tested this on another system I have and it works fine. I'd like $250 for the GPS but I'm open to offers. I also have an A2 IMU for sale which I would ...

I have a DJI A2 IMU unit for sale! This is just the IMU unit. The FC on my A2 system crapped out on me so I'm parting out the other bits. I tested this on another system I have and it works fine. I'd like $300 for the IMU but I'm open to offers. I also have an A2 GPS Pro Plus for sale which I would ...

I bought this for a project but no longer need it. It's a DJI DPhantom II Naza Flight Controller Unit! I'd like to get $60 but I'm open to offers. This unit will work with all Phantom II Quadcopters (Phantom II, Vision, and Vision+) PM me with any questions. Thanks for looking! IMG_20160503_084211.j...

Hi All, I'm selling my FrSky DJT Telemetry Module with a Futaba Trainer Port cable (for telemetry on 9XR Pro Transmitters). I'd like to get $30 for both the Module and the Cable. Works great, has awesome range and telemetry works as well, I'm just upgrading to an XJT Module and no longer need this. ...

Hi All, I'm selling my 330mm Tricopter Build (GoPro not included). I just don't have time to mess with it anymore and need to clear up some space. I'd like to get $300 but I'm open to reasonable offers. Pictures are attached. Let me know if they're not showing up. This rig is 100% built and ready to...

When using the ESCs built in BECs you should only use 1 BEC and only connet the signal wires from the other 3 ESCs to the flight controller.

You may be over-powering the system when you use the Lipo causing something to cut off to prevent damage.

I've been playing around with a RTFQ Mega Pro 2 board myself and I've found the documentation on their site is a bit jumbled and the preset files provided didn't work very well. After doing my own searching I've been able to piece together the Config.h settings to get the system working fairly well....

Hello all, I have a MW Mega Pro 2 board from ReadyToFlyQuads.com running MW2.4 on my Tricopter build. I'm trying to hook up an MTK 3329 GPS module (R-15e) that I had laying around. (Similar to this system m) I'm able to get the GPS hooked up to the board and I can see data is being exchanged but I'm...

So, it turns out the Multiwii Mega Pro 2 board I'm using doesn't output power for the Yaw Servo on the D2 Pin.... you think that would be documented somewhere that's easy to find... :-/ Anyway, I was able to splice a 2nd 5v power line from my PDB to my servo and just run the Signal Wire off the boar...

Still not having any luck with the YAW Servo. I can't seem to find which pin outputs the signal. None of the recommended pins seem to work. I've also tried to comment out the HW_MEGA_SERVO settings but I'm still not getting anything... bah!

I have the RX running on PPM and the ESCs on the D6,5, and 3 pins. The 5v BEC off the PDB powers the system on the 5 pin's power terminals. I have the servo on pin D2. This is what I found for setting up the outputs on a MEGA board for a Tri... is this correct or is there an alternative setup I shou...

ESCs and Motors are installed and I'm getting everything wired up. I ended up having to go with some old 20a Turnigy ESCs I had laying around as the Team BlackSheep ESCs were too long to fit neatly on the arms or under the frame. http://i1284.photobucket.com/albums/a572/SkySpaghetti/Blogs/IMG_201510...

I'm having a heck of a time getting 2.4 to work on my Tricopter build using a MW Pro 2.0 board from ReadyToFlyQuads.com I've posted a thread ( http://www.multiwii.com/forum/viewtopic.php?f=18&t=6772&p=65916#p65910 )and have had a few people try and help but nothing seems to work. Any input i...

I got this error in MW2.4 when I tried to comment out the Yaw-Direction option

Output.cpp: In function 'void mixTable()':
Output.cpp:1144: error: 'YAW_DIRECTION' was not declared in this scope

I sent him a PM. Waiting to hear back.

Which GUI do you use and what MW software?
I'm using the old-style GUI but I've seen that there are other ones now that have a different layout and offer Waypoint programming.

When using MW2.4, I've noticed in the GUI that the Left, Right, and Rear readouts don't move when I move the frame around. The Servo readout works but there's not servo action when I try running onnthe flight battery.

After going over your config.h one more time I can not find anything in there that would prevent arming in 2.4. Can anyone else help out there? My only other suggestion would be to lower your minthrottle to 1000 and your mincommand to 950 and see if that fixes things. Right now your minthrottle is ...

In your config.h I noticed that in both of them you still have not commented out the statement under ******************************** PID Controller *********************************/ this statement: #define YAW_DIRECTION 1 needs to look like this: //#define YAW_DIRECTION 1 You need to add the two ...

Here's my Config.h txt files for MW 2.3:

And my MW 2.4:

Let me know if I'm missing something!

Thanks!

In your config.h file first you need to uncomment the #define TRI statement under the /************************** The type of multicopter ****************************/ heading. Then under /*************************** Combined IMU Boards ********************************/ uncomment the #define FREEIM...

I'm building a Tricopter using a readytoflyquads.com Multiwii Pro 2 Mega board ( m ) and I can't get the YAW Servo to function. I've got the ESCs and Servo set up according to the diagram here m for MEGA boards, Servo on Pin D2, and I've loaded MW2.3 and have the Config.h file set up properly, I bel...

Mocked up the frame. This is definitely a decent looking kit. Hope it flies as good as it looks... Here's the frame minus the top plate. I'm planning to mount the Multiwii in between the two plates for extre protection. http://i1284.photobucket.com/albums/a572/SkySpaghetti/Blogs/IMG_20151010_031518_...

Finally got the build going. I started with the tail piece as it looks like the top and bottom frame plates interlock with the tail. The YAW servo screws into a plate that gets sandwiched between the rails of the tail. http://i1284.photobucket.com/albums/a572/SkySpaghetti/Blogs/IMG_20151008_014501_z...

The rest of the parts finally came in today. I got some additional spacers, the X8R-XP Rx, an FTDI adapter, a protective cover for the Multiwii and a few other doo-dads... Should be able to start assembling the frame and getting everything wired up this week. Does anyone have a good reference for th...

New PDB from ReadyToFlyQuads.com came in today. http://i1284.photobucket.com/albums/a572/SkySpaghetti/Blogs/IMG_20151001_231817_zps51rddb3x.jpg Bit of a size difference from the one that came with the kit. Especially considering it has 2 BECs and a dedicated switch and output for LEDs. Not quite sur...

I attempted to Rit Dye the nylon spacers and nuts today... it definitely worked, though a bit too well. Not quite the "Red" I was hoping for... http://i1284.photobucket.com/albums/a572/SkySpaghetti/Blogs/IMG_20151001_191202_zpshrjipqlg.jpg I'll roll with it for now. Maybe just go all black...

Looks very cool... If you ever plan to use GPS navigation, heading hold or headfree modes, get that power distribution board as far away as possible from the flight controller. The magnetic fields around the PCB power distribution boards are strong and will mess up magnetometer heading really easil...

The frame came in today. Looks pretty good. For under $30 it comes with a PDB, Landing Gear and Tail Servo. It's a little smaller than I anticipated but it'll still work. Just might take a bit more tweaking! http://i1284.photobucket.com/albums/a572/SkySpaghetti/Blogs/IMG_20151001_134710_zpsubelcns3....

I had a bunch of bits laying around so I figured I'd try and put together a TriCopter. I've built Quads and Hex's but never a TriCopter. I'll do my best to keep this build-thread up to date with as many details and photos as I go. I know I'll need a lot of input on setting up the Multiwii system as ...
