| So I am finishing up my MK Hexa XL build using AVROTO motors and Maytech esc's. I am new to the WKM FC and have read the latest WKM manual V2.1. Couple of questions. First in regards to where to mount my GPS and what size poll to use. In the picture I have attached I have the GPS placed on the rigger M4, is this a good place for the GPS to be? Also which length poll should I use, the WKM comes with 3, short, medium, and long. Secondly, I have mounted the IMU directly in the center, my question is in the WKM assistant software in the "Mounting" menu where it asks for X,Y,Z position of the unit do I just leave them at 0 because I have it mounted in the center? I have already updated to the latest FW, and also calibrated my Hitec Aurora 9 transmitter, plugged everything in, and made sure the motors were spinning in the right direction which they are.. As you can see be my photos this is kinda of a custom build with the MK, I used 3 center plates for the build. My Maytech esc's are all on one level, then on top if the WKM stuff... Any other advice....? Oh year I forgot on this build what props would be recommended right now I have APC 11X4.7 would these work? Or do I need to go bigger? -Steve |

Hi Steve, I see you're on same par as me on "custom" build, very neat.
The GPS I have mounted the same on M4 which I am told thats ok, and I've used the medium stick, and the IMU settings i have left at zero as it is bang on centre.
As goes for the prop size that depends on how many cells you are going to be running on. Also what is the size between motor to motor?
Cheers

Rob, I forget to mention I am using a 6200 mah 4s battery https://quadrocopter.3dcartstores.com/QuadroPower-6200-Lipo-Flat_p_368.html
How did you physically attach the GPS antenna to M4? Did you drill holes into the rigger, or just use the included 3m tape from WKM?
Would love to see a picture of your build also

Yes I have used 3M pad and a couple os cable ties. And the motors are those the Avroto 2814 Short Shaft?

Well almost there, Just to verify:
Next thing is doing the setup for the XYZ coordinates for both the IMU and GPS. I have the IMU right in the center so I assume I leave the IMU placement at all zeros ? Then for my GPS I measure from the center of the craft to the GPS for the X coordinate which in this case is 12cm so I punched in -12 because its behind the IMU on the M4 rigger. and I punched in for the Z coordinate 5cm because it's on the poll.
I hope thats correct.
Lastly I tried to do a compass calibration, I flipped the control switch from pos 1 to pos 3 quickly 6-10 times (yes I have my 3 way switching working correctly It goes from GPS to ATTI to fail safe) as it says in the manual,
I then get a flashing blue light, is this correct or should it be a steady blue light?? Then it says to rotate the copter CW till green light is constant, again when they say constant is that mean green light flashing or steady green light?
Oh yeah. I just attaches the landing gear, seems very flimsy, any other options, and I have yet to mount my camera mount... Want to make sure it's flying ok.

nice build Kuau
i agree about the landing gear if you got a couple of pieces of tube you and a few cable ties you could make a couple of skids braced with cable ties as a temp measure
other wise looking nice

looks ok if you mean the first inch from the motors
ive looked at lots of other peoples builds and must admit looks nice and clean running wires inside booms etc
i just keep thinking about the entry point is so vunerable in case of a crash unless you can fit a cap or wire guard of some sort
but it seems thats how its done
have not built one yet so not realy the one to ask but looks good and clean
i used to hate trying to get realy good clean wire set up on me helis as there never seemed to be room to get it all perfect
as long as you are happy does it realy matter what others think
somones probably got ideas as far as protection to wires etc

Build done...
Here is my completed build with averticalview camera gimbal.
Test flown a few times now, Still have some wobble though.
I have some new Graupner E-Prop 11x5 on the way to replace my 11x4.7 APC SF, base on RTryder (Ken) advice.
I have my gains turned up a lot 300%
