Others may have a difference opinion however, from what I see in the second picture, your copter is going to YAW around the greatest mass which is the battery. you were right. i made a lighter bat-holder construction, and put the lipo closer to COG. now it flies perfect, far better than many quads ...

nice program, worked some minutes until crashed.

after installing this, my phone showed "java" errors when starting my other multiwii android apps.

deinstalled it, and all other mw-apps work fine again.

i use allinone-board + drotek gps.

works fine outofthebox on GUI.

before testing outside, i need some info..

do i have to activate baro for position-hold too, or is all done by gps only?
or is it a drawback to activate baro+gps at the same time?

Hello EOSBandi, The Crius does not have GPS integrated. And their price is the price in chinese market without any tax. RCtimer and Goodluckbuy are 2 web stores in Shenzhen China who sell cheap products to US and Europe. You have to know that the TVA/VAT in France and Germany is around 19%. Their f...

the all-in-one pro with 6050 + ms5611 + 5883 is imho the best buy for the buck atm.

thx, you might be right, i didnt thmk about that until now.. copter weight is 650g, battery 3s about 200g? the battery was put there to get COG exactly to FC.... but i ll test tomorrow with battery on top of FC, and with a second battery too. flight time with 2200 3s is about 15 minutes now.

hmm, dont have video, but a bad photo maybe i could make a bad video (cellphone....) tomorrow http://img5.fotos-hochladen.net/uploads/p1010023ypd2n0ocv8.jpg the back motors could be mounted nearer to each other. atm its possible to use 10" props rear too, but thats not needed. then theres too m...

hi, my Y4 Vtail flies nice so far. i dont use Vtail mixing, motors have same spinning direction as QUAD there is only one small issue. when given YAW only while hovering, the cotper flies a circle instead of turning around at one point. its a very small circle (about 40cm diameter). is there very li...

dodecopter

its almost perfect , thank you just tested with my vtail. as i hadnt time to change motor spindirection, i used Y4 define. seems Y4 is very good matching my setup (4 x 1000kv motor, front 10x4, back 8x4 props) used stock settings. 2.1 is sooo nice - first flight i forgot to test autolevel. no need f...

moin, i just tested my new quad with all PIDs stock setting, using 1.9, trusted accZ. flies awesome stable , and even altitude hold works almost fine. i covered the bmp085 breakout with 5mm foam, and put it into a shrink tube..seems to keep the wind away from baro quite good. altitude hold works bet...

the asymmetric attitude is strange on one of my quads i have exactly the same problem. forward pitch is much less than backward. it occured when i switched from a turnigy 9x (which worked as it should...) to a cheap HK 4 channel Tx/Rx mode1. after changed it to mode2 that behavior occured. in my ca...

hello,

would it be very difficult to move that pins, i think it wont be just replacing every PIN5/PIN6 in (HEXA) code with A0/A1 ?
because then Rx input is still missing?

hi, if frame is some distortet, not all motors+props might have the same , exact vertical direction. had a yaw problem with one of my quads with DIY alloy tube frame too - a little skewing one whole arm to the other direction than yaw drift solved that problem. be careful and skew only very little, ...

hi, thank you so much i step forward to get a simple copter into the air for less than 100,- euro. included TX/Rx !! the hobbyking T4A V2 4-channel 2,4ghz frequency-hopping is available in euro-warehouse (important for european - it has CE + FCC ...no extra taxes, and cheap and fast 3 day shipping )...

hi, for my 3rd copter i would like to use a very cheap 4 channel Tx. problem is : in GUI i do not reach the YAW 1100/1900 to arm/disarm motors, the yaw-servo-throw is too little, and not adjustable in Tx. . is ist possible to change the code in order to arm motors at 1200 and disarm at 1800? and if ...

is there any possibility to make a copter rain resistant?

i use this bmp085 breakout with 5V from D12 http://www.lipoly.de/index.php?main_pag ... _id=161167

I am experiencing the same. Without NK attached and 100khz the values are looking good (3000 cycletime). I ordered already a BMA020 in order to replace the NK. Will this problem be solved with the BMA? hi, i am using mp+ itg3205 and bma020, both running on 5V , software 1.6 , there are no problems....

My computer is 2 years old, but I have a dedicated GeForce, it might help I didn't test the GUI on another computer. Maybe I should add a "3D" checkbox to disable the 3D in the gui. [/quote] that would be nice. a older notebook is easily to take with, and its cheap. but often has weak gra...

hi,

just installed 1pre7, tested it holding in hand until now only - everything seems to work fine. (nano clone, wm+ clone, bma020)

but the GUI is very laggy now. looks like video at 1fps

hi, connecting arduino nano to computer, it says : "unknown hardware" but after calibrating the sensors, the arduino gets installed as usual so you always need your Tx (for calibrating) if u want to connect the multiwii to pc. i didnt notice this behavior in prior revision, is it a new &qu...

hi, i was just thinking about using a multiwii-brain as addon to Tx. just throttle and might be yaw would need stick input, roll+nick would be done as with original wii the copter would "copy" the alignment from the alignment of Tx multiwii brain had to do the input for roll+ nick to the T...

what about quads wiht 8 motors , - with y-wires rx to esc`s it should work wih one arduino ?

hi,

is it that wm+ clone with one "missing"chip and itg3205 ?

that seems to work here (1.6pre), tested on gui only until now....

if it does on a wii, it should do on arduino too....

Hi Alex, I have to admit it, I totally lost track in the RC groups thread. It's too difficult to find the "jewels" between the "I received my motors but waiting for my ESC's" posts. So I really hope this forum will provide a better platform for beginners, experienced or "ju...
