DJI's iOSD provides a lot of raw data but makes no attempt to explain it...... The lime green trace represents the rpm of the port or starboard motor and the forest green trace represents the rpm of the starboard motor during a hover in GPS mode with a breeze coming in from the port side. Note...

Welcome Mike..... I'm from Calgary Alberta. sent from my Etch-A-Sketch using both knobs!!!!

You will find that the Hero GoPro3 Black will record videos in HD resolutions well beyond what most computers can handle. That means you will need at least two computers.... 1) a high performance desktop for video editing and 2) a lower video resolution Notebook PC to take with you to the...

My electric RC delta wing remained stored in my garage for many years because of the difficulty of finding appropriate flying sites within our city.... so I eventually sold it and gave up RC flying until recently. Then I bought what I believe is a much more practical machine that can be more...

These ones work well..... the first requires a HAM radio license but they also sell fhss units for those without. http://www.bigredbee.com/BeeLineGPS.htm

The 4S is a 4 cell battery which ofcourse provides a wider voltage control range for controlling motor speeds. Battery current provides the torque needed to maintain the desired motor speed. The depth and quality of the motor copper winding insulation is a function of the motor design voltage...

It seems to happen more often then not for both my F550 c/w Graupner props and now even more on my WooKong on a 800mm Hex airframe. If I recall correctly I was able to adjust the vertical gain on the F550 which seemed to help but that does not help with the WKM on the 800mm airframe. So I...

Here is a cost effective strategy for modifying your F550 to handle more AUW, i.e., heavier cameras. http://www.rctimer.com/product_809.html It enables you to move beyond the limited prop diameters of the standard F550 airframe so that your motor/prop combos remain in the sweet spot for...

It is my experience that one will see a bit of battery voltage recovery about 30 minutes after landing the MR...... due to some electrochemical phenomena...... which is of no use but can confuse some people who were expecting the landing voltage to remain constant. Also a good LiPo battery...

I have heard many good things about these products. Check/serach MRF forum for other comments. The hobby version, i.e., YS X4 controller seems to be about the same size as the Naza which is slightly smaller than the WooKong controller. However, if you watch the videos closely, the YS X6-P is...

(responding with alias account). More practice with a straight and flat railroad line is beginning to make a lot of sense! But in the meantime to get past this first job for my video producer...... I am thinking to properly video a 500 yard straight line fairway safely , I might want to try...

Agreed.... a free waypoint offering should be made available without the need to receive the hardware and the follow-up with sending the hardware and serial number back thru your Hobby Shop, their supplier all the way back to DJI so that they can confirm a valid hw number, update their database...

I have been flying for some time now with WooKong M-GPS on FW 5.20 but just now received the following item: http://www.dji.com/wkm-firmware-and-led-bluetooth-indicator/ 1) Can I safely assume this is the only hardware change to move up to FW 5.22 and beyond or do I need to upgrade any other...

Keep in mind that MR airframe can accomodate props up to 15" x 5p. This means that you can also consider the Turnigy Multistar 4830 420KV motors. http://www.hobbyking.com/hobbyking/store/__26962__Turnigy_Multistar_4830_420Kv_22Pole_Multi_Rotor_Outrunner.html these can be more efficient to give...

I am going to assume that you are using the WooKong M-GPS system..... IMHO I would do intial test flights without the payload... so adjust your CofG accordingly. If you think the MR will be overpowered w/o the intended payload just place a dead weight in the camera gimbal equiv to the weight of...

Thanks for the info on the U8 32 pole Tiger motor. With 8 one should be able to lift a Smart Car!!!!! Re: Torque.... yes additional radius is necessary for all the additional poles and yes swept-ploe magnet area is a major factor but also..... http://www.comfsm.fm/~dleeling/physics/torque.html...

You are asking for a lot with respect to the Phantom..... If you had larger quad or Hex c/w WooKong + GPS receiver you would have the option to use the DJI LK900 Mhz datalink Ground Control Station which will send down real time GPS positions and give you a flight range of 10 km or further if...

I am using the DJI 5.8Ghz FPV transmitter along with a dual diversity FPV TFT display as well as Fatshark cloverleaf, one on the Tx and one on the FPV receiver (left-hand side) the other is the standard omni. I get good reception for about 500 feet and beyond with occassional breakups on the...

IMHO - the Tarots look like excellent products. I would personally opt for the 960 MR airframe which is the 810 but with longer motor arms. Those longer motor arms give you more latitude for future, larger prop diameters beyond the basic 15 inch diameter props that you may decide to start out...
