I would like to know if anyone here has recommendations for the best way to do this. Is it OK to plug the battery in while moving and thus have the WKM initialize while being tossed around? Or is it safest to at least be on shore for startup so initialization is on stable ground and then carry...

There are lots of writeups about this. And if you are super vigilant you can extend the life of your lipos. But lets be practical. What I do is keep batteries between 40-75% after flying, if lipos have more or less charge after the days flying I run them through my chargers store/balance mode...

When you added the gimbal, you added a lot of weight. This will cut the flight time down a lot. I only get about 6 minutes time on my F550 with gimbal and cam weighing 2.7KG, with 6400 3S lipo and Graupner 10" E-props. W/O gimbal I get 12-14 minutes.

W/O GPS you only have Atti and Manual, F/S will just land the MR where it is if you set it up that way (I believe I only have MRs with GPS). GPS and Manual are very different modes as I outlined above. There are some great videos demonstrating this...

There are basically 3 modes: Atti (that is what you must be in now w/o GPS) it is stabilized and returns to level when you let go of sticks and if throttle is at 50% it will more or less keep altitude but drift with the wind and your momentum. GPS is like Atti but also will hold it position...

I have flown dozens of flights with the GoPro Hero2 and WiFi back with no problems whatsoever. This is on my F450 and F550 with Naza and Futaba 8FG Super TX/RX. I have not tried it with my S800 and WKM yet. No need with the downlink and iOSD for the Zen. I am not recommending this, I am just...

That is a great idea, I am sending an email to AerialMediaPros right now to pre order one.

I sent them a link to this video shot with the F550, Naza and a NEX5n: I think it takes a while for them to put up the links. Also I think DJI will put a bunch of them up once the new smaller Zen comes out, I know I am planning on putting it on my F550. I also have the S800 with Zen, but the...

Like I said earlier I can easily make parts for myself, but if you try to make a living at producing parts and selling them, that is another whole ballgame. I don't know any machine shop with lower than $125.00 p/h most are a lot more especially for 4 and 5 axis machines. And the sad fact is...

You do this in the assistant sw using your end point settings in your TX. There are good instruction videos online and it is in the manual. It will be different depending on your TX. Here is one for Futaba 8FG TX. http://www.youtube.com/watch?v=SmDehc5PEUQ&feature=endscreen

The cost of producing any part. To make a prototype of an arm, would probably take 40 hrs, and the cost of materials would be a couple hundred. My shop rate is about $125/hr. Set up to run a small beta testing batch, 25 units. 25hrs. Put it all together and ship to to testers. Get feedback...

I make camera parts and much simpler parts than those arms sell for about $100.00, now we only make batches of 100 or so, these are pretty specialized. I personally don't think aluminum is a good way to go. It bends very easily, even the 7000 series (harder than the standard 6061 T6 I use most...

Any decent with a MR will be unstable because you are flying through "dirty" air, turbulence from the props, arms and the main board. These things are not aero dynamic. And just flying through prop wash even in an airplane (with wings) will cause a lot of instability, rotor craft are much more...

I have flown 3 times now with 5.20, no problems whatever. I never had problems with 5.16 or 5.18 either. 5.18 seemed a little smoother on takeoff than 5.16 and 5.20 seems as smooth as 5.18. I have about 50 flights on the S800, most of them on 5.16. The only problem I have ever had has been my...

Without getting too technical about "title safe" and "action safe" areas on any TV, let me just say that DJI made a mistake by assuming that everyone has a evaluation monitor, probably what they use in the lab, I use those to edit video and they have title and action safe markers that can be...

My 6400 are ONYX 25c 71WH LiPo Duratrax. Gimbal is a MKTR Pro, it is OK but not great. (I also have a S800 with Zenmuse and it spoils you). I plan on replacing this Gimbal with the new Zenmuse for GoPro as this is my secondary Video rig, or maybe one of the new brushless motor gimbals that are...

I use Futaba TX/RC so I don't know your specifics. But on the Futabas it is pretty easy to reverse a switch, just a couple clicks. A few times I have inadvertently changed trim on the sticks as well. I am just saying...

I run a 6400 3S on my 550 with gimbal NEX5n and FPV cam, 10" Gaupner E-props it is pretty heavy pretty much at the max limit. I get about 6 minutes with 20% left on Lipo. If you fly out of spec you are experimenting. As batteries get used and possible abused the capacity goes down. Now if...

About 6 weeks ago I had an unexplained gimbal issue and stability problem with my NAZA that I wrote about here. I sent the NAZA unit back to my dealer and he sent it back to DJI (Empire I believe). I was i a rush to get flying again, so I bought a new NAZA and it works perfectly with the gimbal...

The end points on your TX is what defines the highlighted function of the switches. Make sure you set the TX so that you are in the middle of each option, not right on the edge with your end points. Also test all combinations together with your TX to make sure settings stay solid. I am just...
