Very happy with the structural integrity of the gimbal, apparently if all goes well the controller should be with me mid next week if all goes to plan, then the fun begins getting it tuned in and sweet :)

Result!!, no controller required!!  :laugh:

Jim.

[Coyote]

Lol Jim, the other good part of teh test is if the GoPro had no vibrations showing, the chances are very high the IMU mounted underneath it will have no problems either which I didnt really realize

[Coyote]

I guess I should update this thread :)

A lot has and is going to change with the Tarot. After a few months of ownership now I really like it, last week though, as I thought the landing gear thin carbon brace gave in and snapped. I have put a thicker piece of carbon on but yet to shape it.

Gimbl wise I have been testing one of Marcin`s prototypes for him :





Its fantastic, took me a while to get my head around the PID tuning of the brushless gimbal board but got there eventually :

So I`m pretty happy with that :)

But I`m not happy with the GoPro footage, the one is old now and so much has moved on since the GoPro 1 was released, so I looked at a better alternative to use.

I decided the Nex 5N was going to be my weapon of choice so got one for a good price second hand off ebay



Of course this is going to need a much bigger gimbal so I went for the Goodluckbuy version :



So that`s the camera and gimbal sorted, the camera arrived, very impressed with it and the footage just taken today indoors, it blows the GoPro away.

I will need to preview the shots to frame them, but the Nex 5N only outputs HDMI so I bought a converter too :

Then ordered a super thin HDMI cable to go from the camera to the converter.

Updates to follow :)

This is turning into a 2 man operation - one the fly the Tarot and the other to operate the camera. LoL

[Coyote]

No00000 :) Its going to be no different to how it is now, just bigger camera that`s all. It`s 2 Axis gimbal not 3, only when I want 3 axis I`ll need two people, but that won`t be on this frame, something bigger if anything

[Coyote]

OK so the kit turned up :)

The HDMI converter is nice, lovely image, so I pulled it part :) Stripped the box off, then the RCA sockets as I didn't really need them so I just had the board left.

The Goodluckbuy gimbal turned up as well, looked lovely, total pile of pooh though lol It wouldn't balance, the dampers were too soft and the whole thing wobbled like crazy the whole time. I tried a few different ways to get reasonable results but for £140 its rubbish and I would not recommend it at all.

The motors supplied are equally as rubbish, no torque at all and certainly not enough for a Nex camera. I took them off and rewound them myself to higher specs, but still they just can not deliver the power needed even with a perfectly balanced camera, they would move the gimbal as it should in static tests, but as soon as it was in the air the roll motor just couldn't hold on and it failed every single time.

With the Nex on the Hex the camera sits very very low, too low really, so I wanted to extend the legs, I ordered 12mm carbon arms for the Tarot which double up as extended legs being so much longer. I also ordered replacement landing gear to get rid of the naff and weak Tarot stock aluminum offering.

So first the landing gear : http://www.oomodel.com/tarot-folding-tripod-tblock-dia16-tarot-tl68b16-p-65059.html

$3.59 and great, easy to fit, original landing skids slide an lock straight in, much much stronger :)



The long legs were then fitted and I cut 2" off the length because they were a wee bit too long really :



The gimbal + modifications to get it to actually balance, the gimbal though is coming off as soon as I find a decent replacement available



You can also see the stripped down HDMI converter ( for now ) piggybacked on the gimbal controller board as well

[Coyote]

Goodluckbuy gimbal was an epic fail, its really not much cop, so into my pockets I venture again :)

This time I have gone for the much more expensive but proven Kamkop aluminum NEU BL gimbal. Weighing in at 234g its not too heavy, very well built and can take a Gopro or a Nex camera by only adjusting the camera base.



 

Coming in at £200 + for just the gimbal ( no motors / controller ) its far from cheap, I have bought it in anodized black.

I have also bought the new RCTimer 5010 purpose made brushless gimbal motors this gimbal was designed for, the motors have been met with great reviews so it would be rude not to try them out :)

I have also ordered 10mm carbon tubes to enable my skids to be longer to compensate for the extra height of the Trot now its on stilts as well

Which RCTimer gimbal Coyote?

I was gonna get this one:

[Coyote]

Sorry, done it again ( its not the first time either ) The rubbish gimbal was not from RCTimer it was from goodluckbuy, got RCTimer stuck in my head :)

Not that one, that looks the same as Simon from Desire has, it looks ok

The terrible Nex 5 one I have that`s useless is  : Rubbish Nex 5 gimbal - Goodluckbuy

[keukpa]

Ah, fair play!

Thanks,

Keukpa

[Coyote]

Oh look ! They are multiplying :)



Tarot Quad now added to my fleet, much lighter, I am going to use it for Marcin`s lighter Gopro camera gimbal and keep the Nex 5 on the Hex

[hase2]

nice surprise this one is :)

[dogzilla]

How do you like these frames? Certainly look nice with all the carbon fiber.
