Carapau, That is fine if doing consistent flying but sitting in a hover in light or no wind the draw is far less than flying flat out or in heavy wind. However, as a safe mark I would advise everyone to invest in a Lipo alarm. This can be set to whatever voltage per cell you want the alarm to...

I run all my lipos down to 3.4v per cell to kick the DJI WKM first stage starts to warn me by entering return home. I also have a Lipo Alarm set to 3.3v per cell. My machine draws about 0.5v per cell under load so when the DJI setting starts the RTH I have 3.9v left - well within safe limits...

Come to think of it has anyone ever found retracts suitable for the X650 Pro?

Like Electro 2 I have been using double sided servo tape since 1986 on IC helis, Electric 12th and 10th scale cars, and more recently on Electric Helis and Multi rotors all without incident except I would never use it on servos for pitch, cyclic or tail on a heli because any movement can be...

Yes but unless you have retracts a 3 axis gimbal is a bit like putting a spoiler on your mini bus.....:highly_amused:

The gimbal I have used and found to work excellently is the AeroXcraft Brushless GoPro gimbal (http://www.aeroxcraft.com/index.php?main_page=product_info&cPath=4_25&products_id=41). I have the Phantom version too. They use the Martinez board and performs very well. This video is a little old...

I am interested in this as I too have an NEX7 but brushless gimbals preclude the use of in-flight zoom. Servo gimbals tend to have a far better ability to handle imbalance. However, most are made for the slightly smaller NEX5 so can not get access to the HDMI out for AV downlink. I am looking...

This is the only alternative if I can not get a gimbal capable of behaving as I want. However, it will also make the job of getting what a client wants more difficult, even impossible. Which is exactly why I ask in the forum to see if anyone has achieved this or not. Mixing GoPro and NEX in...

Almost all the gimbals are only for the NEX-5R. This means a SEL-16 f2.8 wide angle lens. Note this has no zoom and is favoured by gimbal manufacturers because there is no zoom meaning to altering of the COG. Fine for panoramic views but useless for close ups unless you move the camera close...

Bearing in mind the cost of a NEX7 I think a rigid cage is essential. Lenses are easily replaced the camera chassis is very expensive.

SleepyC Thanks for that. I hadn't seen that only had an idea for a self build solution on similar lines but this one solves the problem of mounting it on the gimbal. And I do have an SEL-1855, SEL-50210 and a SELP-1650 and it would work on all lenses. Just need to identify a suitable gimbal...

I have a Sony NEX-7 and am looking for suggestions of what gimbals people may have used successfully. However, it is more complex than that: 1. I also have a GoPro Hero 3 Black with a 60 degree lens for Video and stills and still want to have the choice of using it in the same gimbal. 2. I want...

Cable Tie method:=

On my x650 I use Xaircraft motors which are manufactured by T-Motor and have never had to balance them. Even my props only reqired a minimum balancing... Maybe I have been lucky. Although my Phantom did need one motor balancing I did it with strips of electrical tape. My F550 needed no...

You like my signature, I see. Yes years of crashing makes me no better a pilot but more philosophical when it does happen. My 22 year old son has a saying which is so appropriate when disaster strikes - "S**t Happens". It also helps to have the occasional indecent - your spares box grows so...

If you have a UBEC with an output of 7.4v, 11.1v or 14.8v then you are fine. If you don't but have a small 3s (11.1v) then go for it. Mine has two UBECs:- 1. 5v for the GoPro 2. 7.4v for my AeroXcraft Gopro gimbal. I have no noticeable shortening in flight time and still get 17-19 mins flight...

Don't listen to everything on YouTube! If you are using a Tarot and the power input recommended as: Operating supply: DC 7.4V~14.8V (Li-Po 3S is recommended) then any voltage in the range from 2 to 4 cell Lipos is good. Their own documentation recommends 3s cell, which is 11.1v so if you have...

I can see the Phantom V2 Vision being used commercially. It has a reasonable resolution camera for stills and a video usable for most, HD standard. Also the cost would mean someone being able to buy the stock machine and take off at less than a quarter of the cost of more substantial machines...

The first tank I drove was a 1974 Volvo 240 (Wiki). If you looked very closely you could see the welds on the roof where they had removed the turret.....:nevreness:

You will be able to fly from a moving object the compass variations are tiny from magnetic north to true north. When you move East or West of the calibration point by an appreciable distance you need to re-calibrate. The lipos have not got enough power to travel far enough to worry about...
