I bought one of ebay. 148 dollars shipped. Will post pictures and build. If I ever get it....I plan on using a APM 2.0 on it.


Has anyone ever thought to use a three axis gimbal like the use on professional steady cams. High end steady cams have build in weight shifting mechanism to control pan and tilt. The spring system seems, i don't know, error prone. Also, it seems the two axis system on this and the Ecilop are unnecessarily complex.

The kind of systems will work much better with heaver cameras than the light 300-400 gram setups currently being used. I bet a DSLR will really shine on them.

Anyway, great group.


To be honest I bought this more for research than use.

Doesn't like like junk to me. Parts look to be nicely cut. Everything is on ball races. Some of the hardware looks strangely familiar. Similar to a couple of small folding quads I bought from a chinese seller some time ago.
Please keep us updated SunnyHK ....

Hey your the first guy I've heard mention anything about a APM2 since a friend of mine bought one and never did fart around with it enough to see if it flies well. Have you got yours working well? I'm curious to hear more about this fc.

And the next day I shot some aerials for a wakeboard video: https://vimeo.com/42613396

All videos have ZERO post production stabilization. I think that with the correct setup this hexacopter could have similar performance. Although at this stage I would buy the Ecilop first as its a proven product before thinking about the chinese hexa version.

That said I will be first in line for one of these bad boys when they become available.
I'm so jealous of the videos coming out of Aus and NZ! Here in the US you'd need an FAA physical, proof of $100,000 insurance and a signed letter from the chairman of the Dept. of Agriculture to even connect batteries to a flying unmanned object over people's heads. Such a litigious place.

Fianlly , i got the assembly manual pdf from the guy (MR) but that is not the eng manual. i will try to assemble first and share with you guys. also ask him prepare the english manual as well. stay tunned !

Your drone has a separate third axis for camera tilting:



This is a good idea, but when the camera tilts, the counterweight will become unbalanced and will cause rocking. If you want to rotate the camera on a separate axis, the center of mass of the part being rotated must lie exactly on the rotation axis. Here is an example:

I have noticed that the prototype has an electronic stabilization block installed on the stabilized part of the platform. This is fine as long as the block remains horizontally-oriented. On Ecilop Easy, the balance beam can be tilted, so it uses two separate gyroscopes instead of a single block for two axes (more details here).

Another option that helps preserve accuracy is to tilt the electronic stabilization block itself. An example of such a solution used in Ecilop-2:

Ecilop-2 did not have a balance beam and inertial stabilization was possible thanks to the large mass of the part being stabilized.

A steadicam option with a controlled center of mass is an interesting solution that is worth trying.

It's in the works...allowing the boom to rotate in the center gimal will also allow for very smooth xyz space transition. Camera yaw will become interesting, but I think a simple brake on the central boom might work.

By the way Z. I really admire your work. I would have bought one of yours, but I can't justify 700 bucks for a "research project". You really cracked something open here.

My plan for the weight shifting is to have 2 small moveable weights on the counter weight (called the sled in steady cam lingo), one for each axis. I'm not sure gyros are necessary if done right... I have friend that has access to a high end steady cam that I'm going to inspect, and see what i can learn. He tells me the percise blance is key. I think your spring idea might help to damped the effects of a slightly inblanced boom. Also, I think an unequle boom is probably the way to go. The counter weight has less distance to move. Has anyone thought of spinning the counter weight?

Long term I would like to build a steady cam mount that can be affixed to any m. Rotor or copter.

No video

I ordered a frame but I have bad feelings 'cause I haven't seen any video yet. Anybody has something to show?

I'd love to see some footage of one of these birds in flight and more importantly, some onboard footage.

I really find it bizzare that this got to production without an assembly manual.

Nonetheless parts looks good. HK looking forward to your build pics.

I really hope you did not waste your money as im also interested to buy it.

By the way i noticed it has 8 booms do you think it can also be an octo out of the box?

Finally i got some time to build the the frame. i will try my best to upload more update pics for you guys to get more understanding of the frame.
Well, Overall. the frame seems work well to stable the camera , but some of the parts are weak and easy to break. so i just make some replacement by myself anyway. i will show some pics and explain later and will upload some testing video as well. (also , i just notice that MR has show some testing video today, it is uploading on youtube right, From the video,it really looks good to handle the angle.)
Here you go.

wow, this is great! You rock really hard the craft and the picture is almost still. This looks really promising, I saw so good stabilization only using really expensive gimbals.

Please, give us some closer images, some more onboard footage and some details how you connected all things together. Do you use extra stabilization board for cam stab? Or can I use Naza cam stab outputs to servos?

Thanks!
