Majic that is exactly what I wanna see when I power up the FC :-) I am a total convert to this FC... I would rather buy one of these as a RTH PH unit than a.n.other device to do the same thing, once you have a good knowledge of the code and how it works then it appears its limits are infinite :-) I cant wait to set up my new wing I have on the build room :-) Cheers RBS
I'm sure other folks would be interested as well ... I already have a fleet of MWC copters and Flying wings .. might rethink installing this FC on one of them - probably the Falcon Wing as it has a 1.5M wing span and large fuse ... it currently has the OpenAero V1 on a KK board ... so it's not that hard to swap out.
I have just finished my quad and have multi wii 2.3 arduino program uploaded. the board also works fine in the GUI. however when i connected it to the remote i had not control can anyone help. i have not calibrated the ESC's (as i do not know how) and i have not changed anything ing the GUI.
I was also wondering what setting i need to run the multi wii GUI
the receiver i have is a AR610 and i connected all the signal ports on the side closest to the lettering the say throttle,aileron etc.
What MWC 2.3 version are you running? If you loaded MWC 2.3 Nav, the sketch may still be in the PPM (single signal wire) receiver mode - comment back the PPM lines if you are using a regular receiver. Be sure you have the polarity of the receiver correct - signal inner, power middle and ground outer - the posted Rx wiring diagram in the Files section is not correct for polarity. Make sure your receiver is properly bound to your radio. Go to the YouTube Moochasas channel and search for the video how-to for ESC calibration.
the program that i am using is MultiWi2_3-navi-b5-baro_fix.zip from mw-windGUI. i have connected the pins to only the signal ( all wired to the inside of the board) on the board and on the receiver. the only pins that have the positive and negative are the throttle (to power the receiver). i am not sure what you meant by deleting PPM could you give me a bit more help. the receiver is also properly bound.
Now it is clearer. Do this. Download MWC 2.3 from the Multiwii site, uncomment the proper lines (FFIMUv2, etc.) compile but before uploading, clear the EEPROM (file > example > eeprom > clear_eeprom) then upload. If the FC now works with this sketch (as it should), go back to MWC 2.3 Nav and look carefully compare the PPM lines of MWC 2.3 and 2.3 Nav . Duplicate the commented lines of MWC 2.3 and you should be good to go.
i have just plugged the board and the receiver into the computer and looked in the gui and found that the board is getting all the throttle signals from the receiver. and the minimum throttle is 1097
and the max is 1900. but still not motor movement when it is plugged into the copter.
Did you try arming the board? Down throttle plus full right yaw? Did you go through the Moochasas vid for calibrating ESC's? S p e k t r u m radios sometimes have issues with arming ... get your lowest signal somewhere in the 950 level and highest 2000 ... there is a posted doc in Files "what to do when your board does not arm" ...something there might help.
i have now been able to arm the board however my board arms with the throttle down and to the left not the right. and for some reason the board does not arm every time i try i do not know why. i have played around with the settings in min throttle but that does not seem to change much.
Arming throttle down is normal however if you can arm moving yaw lett, you have your yaw reversed in the radio. Open your radio menu are reverse the rudder (usually ch 4). Make sure you reach the required values by adjusting your radio end points.
Q. Has anyone actually managed to use this FC for a Flying Wing or an Airplane Servo configuration? I have a fully working X copter and lots of Brill flights using RTH and PH and all is working well :-) I have dabbled into settings for a Flying Wing and Airplane but neither seems to works as it should! I have 2.4 and rolled back to 2.3 MW using 2.4 gui but it still doesn't work on this FC, maybe I should try another board???? I know some have made a Tri-Copter Shaped airplane....but that's not an Airplane, If its possible then shout out :-) Cheers and Happy Flying... RBS
Go here ... "h t t p : // fotoflygarn.blogspot. c o m / 2014 / 04/ multiwii-gps-airplane. html" (remove the spaces). and here "h t t p : // w w w. rcgroups. c o m / forums/ showthread.php?t=2078096" (remove the spaces). FYI, my tri plane started out as an MWC airplane until I realized a lot of people were building airplanes that took off vertically and transitioned to horizontal flight with obvious benefits.
Hi RBS ... just back from testing. MWC 2.4 works for Flying Wing using D6 and D7 using this board. Make sure the PWM servo line in config.h is commented. Latest WinGUI 2.3 Nav works but the multiwii.h version line needs to be changed from 240 to 230 or a WinGUI connect error occurs. Take note of the servo directions to make sure the control travel is correct .. use WINGUI servo tab to change directions if needed.
Cheers Majik, I got a little way down the line the last time I asked the question but I hit a problem of getting the servos to respond correctly, I guess the PWM servo line will sort that :-) On the flip side of the coin I am still not sure if the FC is a fully functioning board as it gave me loads of hassle when setting up my first copter, the second board worked perfectly so its time to do a bit of swopping to find out if its good to go or ready for the trash, Gonna report back, Cheers RBS
When you know the drill, setting up another one becomes second nature ... I still have to get a "bad" board ... only thing I make sure of doing before anything is to apply clear epoxy to the USB connector so it does not rip out.
Hi guys, I recently purchased a MultiWii Pro flight controller for my quadcopter, I am using a HobbyKing 6-channel remote. I downloaded and uploaded the MultiWii.ino file to the board, and set the correct settings for board type, gps port and baudrate (I changed nothing on the RC section), and using MultiWiiWinGUI I can see my GPS location and that all the sensors work. I cannot get any of the transmitter channels working (in the gui you can see the green bars of where the channel values are at), but they are all in the middle position. I checked the wiring again and can find no fault, the little red LED (on the receiver) goes on when I switch on the transmitter, but no success getting any info about the channel values. Does anyone know if I should set up the arduino file in some way to get it workin?
Some help would be greatly appreciated.
Great unit, with all the features you need for your MC. And the price is awsome, so normally, you cannot make a mistke on buying this unit.If you buy this features in europe, you will pay 3 times as much or more. For the HK price, you get at least the gps module ( sometimes ) but not incluiding the board, wich has a big and powerfull processor also. So another time, where HK makes our hobby affordable. This is what the MC-Flyers need to upgrade their machines.

Received the board today from HobbyKing .
After reading about all the broken Micro USB connectors on other FC like the Crius AIOP , I had a good look at the USB connector BEFORE connecting anything.
The micro USB connector is soldered to the board at the rear corners and also has 2 tabs half way down the sides.
Close inspection reveals that it does NOT have a lot of solder to hold it in place and YES it is likely to break off without some extra solder.
The side tabs do not appear to have been well soldered, my guess, surface mount automated soldering has not applied sufficient heat to get the solder flowing well around the tabs which are part of the larger metal connector shell, using a fine tipped soldering iron, care is required specially on the side near the pin headers, re soldered the metal tabs and also the rear corners of the connector, I don't think it will come off now.
Do keep in mind that is a very small connector and the cable can be used to apply sufficient leverage to rip it clean off the board, no amount of extra solder will prevent that, so be real careful not to apply sideways forces to the cable when plugged into the board.
The quality of the board, the soldering of all the other components, I can't fault it, all looks excellent.
Lots of information now in the files tab for the product at HobbyKing.
I connected the GPS to Serial 2, and the flashing LED
