Still not working. When the battery is plugged in the escs automatically make the arming sound with out the tx even being on but they do not spin. Usually there is the beeping letting me know it is ready to arm. Using opto escs. Gonna go get my kk board out the trash now...
Ken, I assume you are new to this board......... if so it may be a tad confusing (and frustrating) to set it up but once it is done it is well worth the effort........ I have some vids on youtube showing how to set up this board ..... I have also put a link doc in the purple section show how to set it up from scratch (everything you need to know vid)........ I will do a complete set up vid on this board as my new one just arrived so stay tuned......... as its too darn hot to go outside........ godda lov summer down under........ cheers mate
I have a multiwii pro. I have done everything by the book to get it working. After the sketch is loaded and tested in GUI the motors will not arm. Actually the motors make the arming sound when the battery is plugged in but will not throttle up. when I clear the eeprom the motors make the waiting to arm sound. after the sketch is loaded, as soon as the battery is plugged in the motors make the arming sound. I dunno what it could be. Anybody else have this problem? It sucks everything seems to be in order but the arming of the motors.
Thanks in advance for your help
There could be several issue in play ... not to worry, you are not alone. There is a posted document in the Files "what to do when your board does not arm" ... go through the suggestions and hopefully one works for you. Be careful when working with the FC, when testing, remove the props. Good luck!
Proof of concept. This HK Pro board. Tricopter using an Artech WingDragon 3 Ch as a frame. Flies very well - considering. Servos mounted front motors will tilt forward for forward flight but the tricopter feature will allow real VTOL capabilities .... more to come.
The Wingdragon has thick dihedral wings and flies slow and docile which I hope is good for transition. I'm still testing the glue for the wood boom and foam wing and it looks like white casein glue might do the job. Dowels on the wood boom embedded into the wing to keep the boom in place. Wing attached via rubber bands to the fuse (for those RTE's..) will keep this thing together longer by providing a flexible break point. Getting there one wire at a time.
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
