1-CFG-ERR -Re-calibrate your transmitter,and power cycle your controller and check all of the parametersConfiguration error, this may cause by firmware upgrade from old version.or abnormal Tx calibration

2.Connect the X1/X2/X3 channel;
3.Disable all knob tuning.You’ve chose parameters tuning by X1/X2/X3 channel with Tx Knob, but no signal detected on X1/X2/X3 input channel,or Tx didn’t powered on.

I connected it to my pc and opened the software after upgrading the firmware then closing the software and reopening it again while it is connected to my hexcopter it give me those errores

ya but that is too expansive 700- 1000 for just a frame . Has anyone used the xaircraft hexacopter frame ? what kind of motor and ESC can be used with that in order to left 3 - 4 kg any idea ?

I'm using the Xaircraft DIY Hexa frame with Avroto 2814/11s motors and DJI 30 amp esc (plug and play). I fly with one 3s 6000 mah battery and get a solid 5.5 minutes flight before the yellow warning light activates. Right now I'm using a Gopro camera with 2axis mount. My camera mount supports a Sony Nex5n which I have (16mm lens for flight). Everything combined I'm able to squeeze an addition pound for a short flight. My motors and esc are luke warm (I don't want to push the craft...). Almost forgot... I have the 10x4.7 inch APC props (the max for the craft). You'll have to balance strong motors, higher amp esc (40amp) and flight time with your battery. I can get an 11.5 minute flight by running two 6000 mah batteries in parallel, but the motor and esc are luke warm after flying. Each battery weighs a pound.

Hi, P

Is there any reason IMU mounted off centre ? Personally i prefer dead centre….also the GPS it would be nice rear of the IMU bit further ( sit on the boom ) just a thought ! just in case it may interfere with the other Electronics, i will explain in the Video why i prefer have it on the Centre ( IMU) i hoping to wrap up late tomorrow for ya..! Hang in there
Here something to look at it. since we both have the same Bird

I think there would be too much flex on an Xaircraft hexa for an SLR. Small cameras (like Sony Nex 5n w/16mm lens) would work. You'll just need to make sure your motors and esc can handle the weight. I like the look of Xaircraft frames.

I hope you enjoyed the trip if you are back
any how I did
fix some issues I also had a picture and you can see where I installed the GPS and I tell u my setting and if any thing looks wrong to u plz let me know
In software mounting I got this for GPS X10cm Y 0cm Z-17
secon problem is I could not start the motor and also in the software TX monitor at U the courser does not stop on GPS or M it only stop on A when I use 3 way switch the led light keep flashing blue blue by the way in software TX monitor I left the T-R-E-A to Normal but in my Futaba 10 Ch everything is in default except in reverse I changed the THRO to Rev and in Software Gimbal I changed the gain F2 and F1 to 60

it appears you have not done travel check for your flight mode switch.

of 3 futaba transmitter I have setup DJI WKM on, your switch channel should have a travel of 80% and 80%

Yours brings you to fail-safe (blue light flash) because it exceeds the correct travel range of either modes.

Hi
Holiday was a Ok….! i was sick first few days ( Kids had a great time)

Also i like to see both Batteries move closer to the centre plate, you will have a better balance towards the Frame .
Since you having a wiring issues , Please must be follow Dji's manual very important T,R, E, A and U keep all five channels
together which means to your RX 1 to 5 rest of them Gain adjustment , Gimbal roll and pitch, disconnect from the MC for now ( no servo wires connected to the MC X2 X3 F1 F2 ) lets get the Bird off the Ground …!

TX calibration screen blue slider to activate select your three way switch go into TX manual look for End points drop down to 80% -first Manual , second ATT , third GPS

Hi
I did adjust fix that GPS -A And M in TX monitor so now the courser does move to those and get blue but i got problem with fail safe and also when I am on GPS mode it keep blinking green and when it is A it blinking blue but when it is in M no light should not the light be steady not blinking? regarding the throttle when it comes to 10 instead of it goes to autopilot and land the motor stops so if “accidently it comes to that point then the motors gonna shut off and it fall down like a hunted duck
