70Amps 3 axis Alex Mos controller and DSLR gimbal

Hey All,

Quick specs: 70Amps continuous for all 3 axis, burst 280A, 3s-6s lipo (crazy?)

Wind Ranger gimbal: uses high performance Permanent magnet synchronous motor (2 motor for Pitch) can run anything from 3s to 6s lipo)

We are talking pre-order for both gimbal and controller.

I have had the boards and gimbal for the last week and so far I love the board and motors, the board RUN cold, motor run super smooth, you couldn't even tell if the motor was running by touching it. I am not much of a filming guy or editing, so here's a short video, don't laugh. Took me forever to do picture in picture and it's still not right, moving around, not sure why.

Left: GoPro3 1080 60P Right: Sony Nex5 (18-55mm) 1080 60P

Very interesting. 70amps seems like overkill though? I mean, most of us aren't even close to drawing that on a per motor basis on our multirotor!

Will you be selling those motors separately for those of us experimenting with our own designs?

I said the same thing, but you know what they say, you can never have too much. So considering the size of the board is still pretty small... 23A each motor is great.

As for motor, yes, once they finish the 80mm motor they will put all motor on market. ETA about 1 month.

Cheers.

Nice improvement over the standart Alexmos board.

Did you have chance to check this new board with iFlight 8017 motors? Does the torque increase if you apply 6S power?

Thanks.

Does this controller have options to run two motors on one axis? The gimbal you are advertising has two motors on tilt. I am assuming that you are using one controller only?

Curious to see your Epic gimbal

The way how they have the two tilt motor hook to the board right now go right into the same PORT, meaning just parallels. Yes, they have confirmed with me that you can use two BDLC gimbal motor on same axis. But there's a trick to this... :)

PS: They said this is the reason why you want 23amps per port... then you can even use 4 motor per one axis giving the axis ultra smooth operation.

:D

As for the Red Epic gimbal... I am not much of a designer or a CAD person, so keep it simple, strong, functional and reasonable price.

I think you should test it with a real dslr if thats how it's being marketed. Also, dont use OIS as it is an assist that doesnt allow us to see the real stabilization capabilities of the gimbal. You can actually see the gopro has much more movement and is way less smooth than the nex5n's kit lens with OIS, albeit a much wider angle FOV.

Well, the issue is I am not a photography or a film maker, I don't have expensive DSLR camera laying around. The last time we did the Nex5, I have to went and buy the Nex5 and test it... then just sitting there doing nothing. As for the Gopro, I only have these two camera, gopro3 and nex5. The GoPro was fixed on top of the gimbal. As for FOV and all that crap, I don't know those thing. I would thought that the FOV would make it look more stable due to wider field of view? but what do I know?

All I see if it work good, I was running, zigzagging a few time in the video and it work great.

I am not trying to prove it's the best stuff out there, I am just here to showing everyone that's the result I got and new stuff we are getting.

Like the RED Epic gimbal... I am not going to be able to buy a RED and test it... I am just going to put a ROCK with the same weight and put a GoPro in the front of the Rock. haha.

I actually thought the same, wider FOV makes for more stable video-which it does. but in comparison to a better lens with OIS it is no comparison. No worries, not trying to pick on you. I just think if something is being marketed as a dslr or EPC gimbal, that the manufacturer should show footage with a comparable weight camera on it.

So What is it like when used on small gopro size motors?

I am not sure what you mean, using the 6s board for the gopro or these type of motor for the gopro? I can say that these motor have a lot less noise and vibration, run very quite. But I don't think you will gain anything running the 6s board for a GoPro size camera.

I know.... I am trying to find someone that will actually loan me a real camera... easy said then done. Few scratch on it then I have to buy it.. haha.

OK, some quick update on the 6s board... WARNING "For those do no not like high voltage, high amps stuff and think you're good with the 2.5amps board.. good for you, no need to read this).

For those that think, "hey look, mine is bigger and more power full than yours"

- Tested with 8017, it work from 3s to 6s. I have deal with brushless gimbal since the start and I like to set the power on the gimbal and try to BULLY it out of position. Well, let me start by saying, I tried. :) I set the power on 120pts with a 6s and I could not bully it out of position with a 5lbs weight on the axis. I could not set the power any higher because motor would vibrate crazy... probably need more weight to tame the power.... I am not saying to prove anything, just what I did to it.

So confirm, 8017 will not smoke with 6s, but only run warm (100F or so)

uh, yea. you might want to start with a rental. There not bad price wise, but if your gonna fly it get some uav insurance first. Of course were always for hire and come with all that

That's cool. This means this board will handle even bigger and more powerful motors easily.

I wish you had this boards earlier in your stock. Do you have a spare one to sell? :)

Unfortunately I have only have 2 controller, 1 on the Wind Ranger gimbal and one for testing.

Hi All,


I would like to announce behalf of Elite Power about the connecting sequence that they have discovery wrongly (could, possibly) cause issue to the software/hardware.


The correct sequence to connect it to your computer to tune the board is.


Power the board using your 3-6s battery first, then connector the USB to the board then to your computer. If you need to connect the board to PC for a quick change of setting, you may do so. The important part is DO NOT POWER the board with your battery AFTER the USB already connect. For instance, if it's your first time to set up your board, it's best if you ONLY connect the USB to make the initial set up, accelerometer calibrate and ect, then disconnect USB, connect power, then reconnect USB.



However, we are not 100% sure if this could/might cause any issue yet. But just as a precaution, please follow the correct sequence.


Any questions or concerns, please let me know. Also, they will soon release a instruction on how to connect two motor on the same Axis, please wait for further instruction.
