Hi Majik, I recalibrated the Mag and added foam to the baro and all is good when flying in level (angle) mode (no wobble or undulation) I have no idea how to calibrate the compass... it appears to be correct from power up, I am using MWC 2.2 and can switch between level (angle) and horizon modes, The GPS Home is perfect too. All is good and the only problem is with the headfree. Once I have the headfree sorted I have a fully operational copter, I assumed when I switch to headfree it would hold height and position until I switch it off or move the sticks, any help would be much appreciated :-) Cheers Ray

Hi Again :-) As suggested I removed the power distribution board and fitted a harness and it made no difference whatsoever :-( To recap... all works well in level mode but once I select headfree the copter wants to flip if I throttle up from level ground and if I select headfree when hovering it immediately wants to drop the R/H side, The only other problem is from time to time when I'm in level mode and the copter will undulate from left and right but I assume that's the mag and baro sensors that need calibrating, its about 0 C (32F) and a 25 mph wind so its not the ideal conditions for a test flight, can anyone think of a reason why the headfree doesn't work? Cheers Ray

Your copter still have issues related to the compass - symptom is headfree does not work (which is why that is a suggested test.) Low temps will adversely affect the sensors specially the baro and gryo (thermal drift) I've been flying helicopters (gyro for tail servo) tail too long to know that. Last time there was a "Level" mode was in MWC 2.1 - what are you using to stabilize the model? Can't tell you what other things are going on - you can try leaving you copter in the cold for twenty minutes so the whole FC is temperature is the same as ambient - but again that's no guarantee the gyro / baro will not have issues. How does it fly in a large indoors location where the temps are at least above 60 F ? Mave a vid if you can ... I expect to see a very unstable copter in the cold ... but want to confirm that.

I forgot to ask ... how do you calibrate your compass?

So are suggesting that I use the multiwii 2.2 instead of 2.3?
 majik01 7053 points
If you have never used Multwii, go with MWC 2.2 for now. It is not as complex as MWC 2.3 ... just getting to the config.h of MWC 2.3 can be a challenge ... let alone the configuration. There are also the MWC 2.3 Nav beta versions ... do not touch those yet. You will find the MWC 2.2 multiwii configurator along with the zipped download package for MWC 2.2.

Thanks for the reply and advice, I'll probably just stick with 2.3 only because it seems like more sketches and discussions are in line with that. I've done some exploring in the config h and with me using a MAC and OSX, 2.3 is more Compatible.

Go several posts below to Andrew's experience ... just saying ... up to you.

Another quick question, is there a GUI of OSX? Using wine to run the windows GUI on my Mac doesn't work due to the fact it looks for those other window sub type programs like NET and C
 majik01 7053 points
If you install MWC 2.2, there is a Mac version of the GUI included in the download. If you want to go deeper into the hobby might want to get a MS machine as MWC 2.3 Nav will only support windows for now.

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
