flaw?

May I have a question for the manufactures? – Seeing some of the videos using the AlexMoss controller I noticed not leveled horizon when the copter is in forward flight- turning.
Is it because the controller cannot cope properly with the G-force in the turn?
If I am wrong can you post a video proving properly leveled horizon in a turn?
My original picture that should dokument it did not have the system on board. This new picture has it.

The picture you posted is from the video that is not using the alexmos gimbal. You can see it in the comments on youtube:

It's completely RAW.
50$ gimbal and cheap analog servos that is.

Sorry for linking to a different shop.

edit: the sensor was included..
Pleeeze, folks!
There's nothing wrong with linking to other shops but this will add up to a massive confusion!

1. Make sure to read the first posts in this thread again frequently. It says 99€ or less for the complete controller, available in 2-3 weeks.

2. Ask CSG_EU to open up his own thread to answer your question there:

The upcoming SBGC controller from ViaCopter/Flyduino will have a separate IMU and the USB will be onboard. So you'll be able to distinguish both sorts of boards: the original design from Alexmos (using an FTDI/USB connector) and the design by Felix aka ronco.

It would be mad to hang all the weight of roll + tilt mechanics + camera on small brushless motor alone. There are two routes to take:
1) Use bigger motor with better bearings and thicker shaft
2) Use separate bearings for support and the motor only for movement

I'm planning to go with option 2 although option 1 comes also to play in form of a bigger motor needed for heavier payloads. I'm still holding back since there's no controller for bigger motors & heavier loads. ~2A of AlexMos controller is not enough for motors able to move DSLR class cameras (I think).

As a side note, is there any specs for maximum amount of poles the controllers can handle? Some DualSky motors have 28 poles and I'm planning to use those for smooth operation. IF the controllers can handle that high a pole count, that is.

You mean the sexy aluminium gimbal from E-Copter?
Fabien maintains a list of interested ppl on his site. His price tag is at ~500 Euros (maybe less)

The original Viacopter/Flyduino gimbal like shown in Jussi's videos will hopefully be available around mid February incl. fully intergrated all-in-one controller, rewound motors and the GoPro gimbal mechanix for 300 Euro (maybe less). The controller itself will come at around 99 Euros (maybe less).

Fingers crossed!

We are probably gonna be closer to 350 with VAT for the complete gimbal, but if it turns out to be cheaper to produce than estimated, we will translate that into lower retail price.

Controllers should be ready inside the next 2 weeks - but its not a promise

We´ll also show samples of motors soon...first samples are already enroute from a well-known top brand.

Agreed, but I can't find any right angled mini HDMI male to HDMI femail connectors anywhere. Do you have a source? Would appreciate anyone who knows where these can be found sharing a link.

I hate to correct you, but:

The IMU will be included, but its a seperate unit, since it has to mount on the cam...the board is similar to Alex´s original design, but uses better Motor drivers and we took the option to add a CP2102 USB-serial converter to the board. Serial lines are still available for wireless tuning via BT or other Wireless serial link.

Pls let me and Sebastian take care of the tech questions...I know you mean well, but the facts has to be correct, or it will just add confusion...

I am pretty sure that the 2.2A /7.1A burst rating should be sufficient to swing a DSLR with a short lens, but I wont know for sure until we have had the chance to test bigger motors and rigs. We are focusing on smaller, commonly used cams to begin with.

In any case, there will be a solution for higher currents and third axis soon - but I am not gonna give it away now... stay tuned!

28 or 32 poles should not be a problem, in fact it would be an advantage in terms of smoothness and cogging tendencies. The SunnySky/DualSky motors would be my preferred choice right now for a bigger load.

I too have seen at least one other video showing the same poor roll performance. I am sure the team are aware of this and will have this worked out before release (I hope)
