Hey Gor ... did you get a sudden "interesting' feeling in your gut after you read this question ??? Mr Tech ... how did you set up your Aux switches and what MWC version did you upload? Horizon is flight mode that you enable in the GUI ...
well I finally got mine set up and functioning. Everything is working except that the quad wont take off. It is wanting to pitch forward as if the front motors arent throttling up at the same speed.
I have done everything I know to do(which obviously isnt everything)
I have calibrated the ESC's...but i did it the old way...connecting the esc to the receiver.
Do I have to calibrate through the MWP?
should I clear the eeprom and load another sketch?
No-worries Todd,,,alot of people go threw this at first. By all means clear eprom FIRST! Then check a couple of stupid things like your craft actual balance (often overlooked) then,,given you have done all that YOU want to do with the sketch. I would sugjest if you have compleated the individual proceedure of calibrating each ESC with the receiver method (Mooch: has a great video on YT) on how to calibrate your ESC's no matter how many,,,,,then go threw the "Cant fly" method of calibrating all your esc's threw the board. This actually works quite well,,and Mooch and Majik both have how to's on this subject on YT, and I beleive there is a file on "cannot fly calibration of ESC''s",, in the files section. After this clear eprom again and reload entire sketch. Level the table, then sit quad, hex, octo, on table that you already have run a four foot level on. If using the MTK GPS unit,,,"you have to be outside"!!! I dont care who you talk to it just does not cold start or even fire well indoors. Power up the board and hopefully you have a laptop at the table or pad using adroid "EZGUI" and do your ACC and MAG calibrations in an area hopefully devoid of large metalic objects. Once all this is done and you see the little LEDS to the right bottom to board showinig sat data packets coming in,,you should be ready to strap down craft to table,,( I like material covered bungy cords),,,,cuase they allow allot of movement but wont let copter fly away. Now your ready to test each function and see if your pitch, roll, and yaw are right. After that,,,toss some salt over your shoulder and taker her up. Unless something is really wrong,,,you should be air borne. It helps when you have a problem to give a break down of what you built and with what components. But there is alot of help here. Keep after it and come back and ask again. Hope this helps. :-)
Mooch that is so awsum,,,just like a little fighter plane vantage point. Personally I dig how you get the props in veiw with video, I think it is important so you can see performance and potential problems. If that is winter buddy,,,,I want to move. Is summer just awful hot Mooch? I mean if winter is that balmy is summer a pain? Anyway just thought you might want to know your jelly is done. and I still havent got an email Tony to send it to. That makes it difficult, expecially when the wifey says to me: "you better tell your buddy in OZ to get off his butt and get me a destination or your son will steal it". She looked serious,,,,lol Huckleberrys are coveted here in the Northwest US. See it pays to be a tutor and buddy here on HK. I'm probably have to get Gordo some too. I looked into getting to Holland and Britain, but Britain may be an issue because of the seeds?,,,,WTH is up with that?
I cannot confirm the fact but here is what I heard today.......... our company has just started to engage a company to fly a hexa and a quad to do inspections around our site and I just happened to wander across to chat to them.... anywho they have just won a contract to put together a training package for (get this) our high school kids as an elective subject which will be available next year...... also the training package will be open for people like us to gain certification...... thats all I know at this point.... I have some great footage of them flying their $20k hexa ....... they are just investing in a new machine which will have infra red sensors for close proximity flying..... Some how I feel this is going to be an ever opening field of business opportunities....... Imagine doing this for a job??.... and how much work do they have on??????? the 2 guys I spoke to cant keep up with it all..... one flies while the other operates the gimbal and takes the shot..... now thats what I call money for nothing.....
Me too, me too ... except I want to include remote sensing of the crop condition with IR so farmers can determine the "health" of their crops ... I've got the birds but I'm still waiting on my sibling to share the process and technology for remote sensing ... he has a PhD is Geology and specialized in satellite imagery ...
How about Arduino robots? The Arduino controllers and robots parts can be purchased here at HK ... the program is open source. Our machines do not just fly, they can move on land and water ... how about a FPV fish hunter? Or underwater video rig with BL gimbals enclosed in upside down fish bowls ??
Well, we got to do the test flights inside the nightclub, It came out really well and we are already OKed for the next test with all the lights, smoke, lasers, etc. going while we film. If I can find a small gimbal for the Mobius, we might get a paying gig out of this. Indoors. No FAA. Unfortunately, I have been asked not to post film before the video company does, so I have to wait. All that flying I have done around the yard in close quarters around obstacles really paid off in the club. Newey, I wish you were here - you could make money doing indoor gigs in this town.
Gordo I would love to, and I too have allot of inside experiance. I held in my hand the best black version of GoPro3 and the Sony 700 series and have a new best freind in the camera department. The four lens options are a big selling point. I dont have one but my partner in the mad sience department does and the video is outstanding filming a pool party at his house. I would definatley have to move to a different state though,,,lol :-)
We are a patient bunch ... we can wait ... your twenty seconds are up ... where are the vids !!! Hey Newey ... the GoPro 3? That's awesome ... takes some killer vids that one does ... you too need to post Newey vids
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
