Flight Stabilization System integrates the three-axis gyroscope, three-axis acceleration ,which make up a basic platform inertial navigation system. It can calculate the attitude of the model plane by a special algorithm. Once the Flight Stabilization System detected there is change between the model plane’s present attitude and the horizontal attitude, it will give a controlling signal to keep the model plane in a state of equilibrium. The Flight Stabilization System can be used very easily. The manipulator just need to place the control stick in the middle of the remote controller, then the model plane could revert to the state of equilibrium. The Flight Stabilization System can be used in any environment, such as indoors or any weather conditions. It dose not need any other initialization. Just switch on the power then the model plane can fly to the sky stably. There are three control knobs for controlling elevator, aileron and directional channel.

oooh but does it fly? well good question... I was finally able to test it today. I have had it installed the day I received it but unfortunately the only version shipping right now is PAL and I needed NTSC.. so I had to order a PAL camera and of course I don't have a PAL compliant camcorder... so no inflight video but here are my impressions.
First few flights I would go into stabilization mode and belive it or not the thing would flip itself upside down and fly!!! I was impressed... but not that impressed hahah... I had the throw going the wrong direction... oops...
After reversing the aileron throws (just the turn of a screwdriver) I launched again.... this time no flipping... actually... it's steady as a ROCK.... I then banked... it leveled out.. perfectly... actually it leveled as fast as my stick went back to centre.... then just stayed there.. no rocking.... nothing.. so I pull up... it goes straight back to level when I let go....
ok sounds good now how about elevation hold.... I switch to stabilition with elevation hold... perfect....
on to autopilot... switch to RTL and she comes right back home. It holds a nice tight circle of 120m around me... I send it back out... hit position hold... it circles around the point where I hit it... I am impressed....
Watching the video while in Autopilot the plane does rock back and forth a bit.... I have no rudder so it does have to bank for it's turns. I did not have a chance to dial the gain down much. I did one flight with slightly reduced gains and it did reduce the rocking in autopilot mode. No it does not rock in stabilzation mode. It's not as smooth as my atto but I have not spent any time dialing it in yet.
If I cant reduce or remove the rocking... do I care? no. will it come home? yes and that's all I need for this one.
ok so I did this a few times and then started to watch the video... here is where things fell apart a bit..... with throttle on the screen goes very fuzzy, more so than usual when powering off one battery. I would say this osd is very susseptable to noise.. more than any other I have owned. I throttle up and the video goes bad and the osd text slides down so you can't read the bottom lines....
Ok fine so I have some video issues. powering off a separate battery may fix this or I can put an anyvolt micro in (that usually solves some lines but this may be too much)
It could be a pal issue but I am not sure.. my screen that i fly by can read pal and ntsc so I am sure it's a power thing. This osd needs clean power.
So all in all I give this osd (SO FAR) a 8 out of 10... if it came in NTSC I would give it a 9 and if the video was not so prone to noise I would give it a 10...
Any questions feel free to ask. Oh and BTW so far I would say the stabilzation alone kicks FMA's butt.... I have installed FMA's into many airplanes.... and ripped them all out... they are paper weights.
