Tahoe Ed..... I bought the WKM from UAV then purchased the GCS from National Hobbies while on vacation in Mesa Arizona....... So....... WHich of the two dealers provides me with the new serial number so that I can get GCS to commincate with my WKM....... Or is that still required for the new...

Thanks for that feedback......I gleaned a few items from it. But I was under the impression that the new offering which includes one free waypoint was all inclusive for the $520 hardware/software package and that a change to the serial number would no longer be required....... If it was changed...

I am very eager to get the DJI Ground Control Station software up and running with my new WKM. I bought the LK900 Mhz (DL900) version. And for a price of $520 for the package my expectations are high in view of the price and excellent quality of the other DJI products which I own and fly as...

Thanks Ed.... Obviously it is possible as per the photos..... will put on my thinking cap and do up a diagram then connect accordingly. I assume you are using 900Mhz datalink for Dji GCS.

Keep in mind that any charger that claims to be able to charge two batteries at one time but with only one charging port, will have to do the two batteries in series. Regardless whether it has two balance ports or not, that type of charger can only push a common current through both batteries...

Turnigy Nanotech IMHO...... There has been a lot of talk in the Carbon Fiber, Nanotech, Graphene world that nanotechnology will revolutionize battery designs. Turnigy claims to use a LiCo nano-technology substrate complex and if so we can all reap the benefits of that. Also the newer LiPoly...

If you must use 8 awg, which I consider excessively larger for anything smaller than a Nuclear Power facility ;-)....... I would avoid using the Deans plug. The airgap between terminals is too small and there is not spearating insulation except for your heat shrink which is not intended to...

You can easily relocate your GPS puck and mast to the opposite side of the center plate. Then make the appropriate position adjustments to the controller config using WKM assistant software. Every centimeter counts.

Maybe the issue is inside your PC. Have you activated MS device manager to look for problem driver installs?

SRBell, Interesting.... as we are both into High Power Rocketry as well. I have plans to turn one of my Multirotors into an aerial remote control launch pad but for a small b or c motor. Currently flying a carbon fiber Mongoose 98 knock off and hoping to achieve L4 certification with at this...

By far the best decision one can make for a reliable long range data link is to locate the GCS baseas high as possible and the antenna as high as possible above that! The MR antenna location is far less critical. Good to here there are others into GCS as well on this side of the border as tech...

Key benefit of pointing the LK900 Mhz antenna down versus up are: 1) No signal path attenuation from MR airframe metal and CF components. 2) Less chance of the antenna repositioning in flight to get clipped by on of the MR props (assuming prop diameters could be that large relative to antenna...

Since you are both installing the 900 Mhz datalink, where did you find the spare canbus port? Seems I have to install the iOSD to get the spare port since the WKM doesn't have enough by itself to support LK900. According the the HAM radio course, your best range is achieved with the antenna...

That works 100%...... Now I am still missing a Canbus port as required by LK900 cable sets. Seems that the iOSD that I ordered with it will be the only way to increase the number of ports to complete the job!!! Or am I missing something here? The WKM controller provides an s.bus port but will...

Thanks again.... your guidance helped greatly..... in the meantime I am getting a statement when I select "connect" from GCS stating "permission denied"!

Chris.... your help is greatly appreciated..... But how do I edit "hosts" and save it without any extension and save it to the same location? Windows OS has restricted me from saving files to this subdirectory even though I am the administrator!!!

The following message appears when I first tried to install DJI Ground Control Station using my new LK900 radio system and the provided CD software for my new WKM. Message from webpage: Error! There are 2 possibilities... 1) network is not good, try offline mode... 2) google earth plugin...

Some progress now that I am past the defective cable including com link thru to MR transceiver (I think).....but seems I have to notify someone of my existing WKM serial number so as to get Ground station to work for single waypoint. Also the Google Earth plug-in seems to not be working...

The problem was traced using my multimeter to a faulty USB cable as supplied from the manufacturer...... USB cable was probably an untested 3rd party product!

after the initial panic and about 15 minutes waiting time, I decided to remove the Notebook battery and try again to reboot from the 120VAC powerpack only and it booted up this time. Might be a thermal reset fuse/breaker in my ASUS K61IC Notebook PC ..... Will now do a continuity check on the...
