I would also like to see a setup with military grade components, but I don't think someone is going to invest that much
At the moment it seems that we are unable to get Zenmus-like output from it (some shots are not far from it, but longer sequences are quite difficult to do). If that is what you are looking for, then you must search elsewhere.
I think Ecilop is a great piece of hardware and you won't regret if you buy it.

Stanleyy..I am also looking to get as much information as I can before getting a new frame. From what I've seen Nyc's hoverly combination looks very close to zenmuse if its not post stabilized. I think there is potential in this sort of stabilization but unfortunately its not completely tuned in by Alexey. I'm waiting to see more of the chinese clone and than decide what to do. I certainly wont spend zenmuse money even if I had it.

Just saying, I think it's better to support the original than clones. That better supports further innovation. But there is definitely a lot of config involved so I get that.

Yes, the extra weight seems to help a little but i would rather strap on a larger battery than stacks of glass. An 18mm prime would be perfect for my needs.
Have you tried the 19mm Sigma? I haven´t put to the ecilop so far, but IMO it gives a lot better results in stills and movies than the stock 16mm.

gonna put some more expo on the rudder to make it smoother, but i was just flying around to see what the footage would come out like. just converted from 1080 50p to 720 25p.

AliB,
that is looking awesome! :-) Great job setting up your gimbal! That is what I actually wanted to see. Thanks!

looks like your gyro+servo combo is working fine there is some offset caused by FC loop, but that is not so important.. looks good to me.
what about fast descend, how does it behave?

I didn't mean fall from the sky, just a normal usable descend.. My Naza is very stubborn and doesn't want to go down so easily.. And in most cases it wobbles when it is descending...

You should also try to install custom firmware into GY520, there you can adjust really everything...
Naza DOES have really "bad" PWM for servos. Known issue about which DJI does not give a crap. I was told "Naza does not like some servos", what a joke!

Another known issue is descent wobble. You can't fix it. You can make it better or worse by settings, heavier copters wobble less but they do no matter what your settings are.

Check this out and turn your volume up to hear that crap. First part servo connected to MultiWii at 300 Hz, second part I reconnect roll servo to Naza at 400 Hz (refresh rate actually does not matter, Naza sucks at any freq). MKS servos a kind of work better with Naza.

hm, I increased pitch/roll gains and the descend wobble improoved a lot.. but I agree, it is not what I expected from a device that costs 500 Euro with GPS.
What controller are you using instead of Naza?

not had any real wobbling while normal decending. could be due to using 11" prop instead of 12. higher prop loading.
i got my gains around 140 and attitude at 80ish

what does yaw gain change? not really played with that at all. just left it at 100

I am still using Naza. Except those two things is't a great controller otherwise (I had KK, MWCs and FreeFlight). Exceptional alt and pos hold, auto level, much better than MultiWii. I am lurking in Autoquad thread, that FC looks promising, but initial calibration sounds like a bit of headache. Pricing about same as Naza + GPS and a lot more features.

You'd need to redesign the landing gear for X8.
Hello Redsky

Can you please comment a bit more on your experience with a 910g payload ?
I also need a better lens (and camera) so I will be looking at similar payloads (even maybe 1.1kg ...)

I will probably wait for the octo, but I am afraid it will be a non-foldable monster to transport (no car in tokyo ...) ... so if I can make it with the quad ...

If you mod the arms to be a 8 (not x8) you don't have to redesign the landing gear.
I have an idea, but not enough motors, time to build it. Easy build by the way, using the same style as ecilop frame. :-). So it won't look ugly.
