The MultiWii PRO is a gyro/accelerometer based flight controller that is loaded with features. This version of the MultiWii supports direct connection of a GPS module (package includes MTK 3329 GPS module) allowing for ultra-precise positioning functionality. With expandability options and full programmability, this device can control just about any type of aircraft. This is the ideal flight controller for your multi-rotor aircraft.

Most of the documentation on the web and on this site show the wrong placement for the signal pins on the board. You need to look at the printing on your board before connecting your receiver. On the current board the signal pins which connect to the receiver are on the INBOARD side of the unit, NOT THE OUBOARD side as most of the documentation shows. I hope this post saves you from the many hours of tedious problem solving that I went through.
Majik, I must say I salute you :-) its brilliant that people like yourself and mooch take the time to help others :-) I am gonna start with a fresh download of Arduino and follow your you Youtube..., I can only assume I have altered something in Config H or Multiwii H when I was trying to figure out how to make it work, Many Thanks RBS
Majik... Its sorted (Big Smile) Once I started with a fresh download and followed your youtube clip both servos started to move :-) From there all I had to do was set the channels to factory setting (Not Reversed) and make sure the correct wing servo was in the correct D6/D7 plugs, Along the way I noticed the extended AUX setting so I've had a play with that so I can use my 2 spare channels to give me Mission/Level/Mission/Pos-Hold/RTH, Also I plan to use the rudder to Pan the camera, The Build can continue :-) and I will definitely make a Youtube vid for others, Once again Many Thanks to "The Guru's" Keep up the Excellent help as I know lots of R/C enthusiasts appreciate it.

Glad your board finally decided to cooperate - let the innovation continue! Anywhooo, I did come across the extended Aux settings ... I forget how many per Aux channel but having that option and say a Taranis radio means you can set as many flight modes as you can possibly like. With two Taranis three way swtiches, you can have a max of nine (3 X 3) per Aux ...the APM uses six on Ch 6 for Arducopter and six on Ch 5 for Arduplane ... MWC can use four Aux channels now with more than three .. that's a lot of flight modes ... and the increased potential for mode conflict ...
Wind and rain finally stopped for a moment for some tests. APM 2.5 on a HK S500 frame, Taranis and Flight app on a tablet via OTG ... does not have the same flexibility as the MWC Pro boards as far as flight modes are concerned ...
Majik, It looks a very stable platform, This is why I like Copters :-) I think there will always be lots of new tech stuff hitting the market, I am pleased I started when I did, for those who have grown with the tech its easy pea'sy :-) The good thing is having Guru's and internet forum help, If it hadn't been for the help here on this message screen I would still be scratching my head lol I think I have only scratched the surface of what is possible, RBS
So very true Ray ... thing is you have to get your feet wet ... make mistakes and learn from them. Having said that, I found a way to "add" the equivalent of MWC Head Free as an add on to any flight mode ala cart. Awesome, awesome ... this means the copter can be set at a fixed height, made to turn towards the desired orientation (to take a pan video while moving for example) and yet fly the copter without worrying about orientation. This can be done easily with the MWC Pro board ... horizon, alt-hold, then head-free ... much simpler actually.
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
