Nice triafgg.  Just got home, printing the fake cam and motors now.  But they printed fine Steve.

Hi guys, great progress in one day. Gimbal looks nice. I can only say that there will be problems with the inclination when we fly sideways. Turn should be more than 45-60 degrees, you need to take the camera forward in the nose of the mavik or lower one support. I already faced this on another Gimbal, if the camera touches the case, there will be paralysis in flight.

Great prints them triafgg.. Hoochster, your pictures are gone again?

So as Yura has pointed out we need to confirm the following now. 

1. How much movement does the gimbal have. It will need I think about 40-45 degrees of freedom left and right, this is when the camera pointing down at 45 degrees. Does it catch on the top and back at all?  You should be able to put software limits in it to stop it banging after this point and prevent it going silly in flight.

2. We need to make sure the camera + side motor is in perfect balance for the rear motor to move. It may need moving left or right on the back arm to find this.. The weight of the camera is 66g, motor is 20g.

3. Are the two screws the best solution to hold the camera in place? Would you all prefer a quick release way instead? 

Please if you see something you could do better then tell me.. In the end it will only make a better gimbal :-)

The 4th thing is I need a new printer.. lol I've had a nightmare lately with it!!   I think I'm going to have to buy a new extruder and design a new housing up for it!  Not sure if the ramps will do self leveling but if it does I'll add this too.. If this gimbal works then great .. ;-) My printer downtime wont effect the project!

Any other suggestions regarding the gimbal / design?

Other than you can't plug the dam usb cable in mind.. opps

So Hoochster, 

What do you think ?

Oh, and thanks to you all for printing these out and letting me know. Gives you an idea of size, fitting etc..

It's nice, the cover won't fit anymore, the dome that is haha.  But I assume you realize that lol.  But that isn't necessary.  Just takes away from the original Mavic look.  But I am ok with that.  I printed it pretty lightweight so hard to say without having motors and the camera on hand, let alone I have never had a gimbal before.  But it seems to fit the bill.  If this is the one we think we will go with, I will get the motors and cam on order just to get more of an ideal weight of the thing.

Hi Hooch, not sure if it's the one or not to be honest. lol I think we will use the motors without a doubt as nothing else smaller is available and yes, you loose the mavic look but I don't think we have a choice.  Still I don't think it looks bad and gives us 1080p recording which is great. To be honest although my real mavic does 4k I don't have a 4k TV or monitors to support that res!

Right, work time.. hopefully wont be late today!!

Steve, unfortunately your stl files do not open for me ... That's what I meant at the expense of slopes. It turns out quite a huge design, taking into account the size of the engines ... From the top there are suggestions to make a site for Rubber dampers, if do not use the 3rd axis. At the weekend I'll think about it, good luck and good mood

Hi Steve

Have you looked at the Mobius2, same spec as the runcam, 1080P/60fps. It is more expensive though.

It is slimmer vertically so might fit better than the cube. I found that the gimbal mount with the cube nearly touches the ground and might need to use the leg extenders if it hits the ground during initialisation.

I was thinking a mobius mini would be a good contender for this; it weighs about 30g and has a much smaller form factor than the original mobius aswell as most other cameras. Not only that it shoots in 1080p at 60fps.
Just a thought.

Yes I think the mini would be good. The thinner height would give it better ground clearance, although it would stick out more at the front.

Also it's cheaper than the Runcam.

It can be set to start recording on power up as well when powered by the USB port but I would imagine the Runcam has that option as well.

With the extra ground clearance, some rubber vibration dampeners could also be intergrated into the design.

I think the problem with the Mobius is the length.. because its so long it need to hang out.. and further down if you want the camera to tilt at the floor. Although the runcam is higher, it actually needs less room to tilt to the floor, if you know what I mean.

Sadly my printer is on it's last legs so until I get it sorted I can't really do much more. I've been trying all day, spent stripping it down and trying to get something to work out of the parts I have.. It keeps failing at the moment through prints, the filament just stops. Motors aren't warm as its not missing steps. Not sure if its the filament... keep swapping stuff out and trying again. Although I have been on amazon looking at new printers.. lol but Mr Bank says no.. and more importantly, so does my wife.. lol

Back up to full speed soon I hope.  New x carriage design..
