My Posts This: Topic Forum | I wont go into how to set it up because the instructions are available online. To me it seems like a lot of instructions to follow at first, it was like I was learning to set up a helicopter for the first time. The instructions were obviously translated from a german language because a lot of it was hard to follow, so there is a lot of thinking outside the box in order to get it done.
I hate reading threads were people get to far along in talking about the product before the talk about flight performance so I am going to jump right in. this will be in comparison to the stock Predator Gasser and not another Flybarless system. It was a noticeable difference during the initial hover. The instructions tell you not to pre-compensate during lift off and to quickly go to a 3 foot high hover. totally not a normal practice for an experienced pilot. now after you get past that the heli flies like it is not totally your control. it is very locked on per-say. let me explain. it stays were it is programed to stay verses were you put it.In the instructions it also says that you should not trim it if you are using Beginner mode, and I planed to do so but during the initial set up you must fly it in standard mode first.I had to make a few adjustment to the I and P on the rudder but left Aerilon and Elevator settings the same. I did how ever change the ATV on the radio to make it much more responsive than it was . it was very docile/ very beginner style flying.
One thing I need to point out before I describe how I felt the Gyrobot 900 flies. If you have it in beginner mode you just hold the sticks slightly in the direction opposite of the drift to trim it out release when the heli is staying in that spot. ( Just like a heading hold gyro but a lot slower to react to the hold position. now back to standard flight performance
It flies like this. It is defiantly not on its own when your sticks are neutral (hands off) it is really stable not much of a difference in standard and beginner mode here, But the difference than a flybar heli is this flybar helis will tip once balance is lost and you can move the sticks ever so slightly to correct or it will crash. with the gyrobot it is not that responsive in the middle until the Gyrobot realizes that you really mean that you want to move the heli. this is good if you fly behind the response of the heli but if you are like me were I have a GOOD habit of flying ahead of the heli ( not waiting for the heli to move before I react)then you will be chasing your own movements, correcting for your own mistakes. after several flights I have gotten used to it, and I had to really bump up the ATV.
I do see a slight increase in performance due to the less rotating mass, and I had to alter my throttle due to how much faster it spools up increasing my head speed to much during certain pitch transitions. now if you are going to use it for AP then it does Drift in beginner mode, much more drift than I think it should. it will be difficult to get a shot off in the spot you want if you rely on the Gyrobot. Now don't get me wrong it does keep the helicopter very stable (horizontal) but if you fly long enough you know horizontal flight does not mean it wont drift. there is always a slight angle of attack for a heli to remain in one spot. I am still working on trying to get this problem worked out since this is what I bought it for and I feel that if this thing cost this much it should do it.
I have not tested beginner actro And I don't really wish to since I bought it for AP and I have three other helis that I use for 3D flight and I really don't think it teaches inverted flight well and Someone should not depend on it as a recovery do to the fact that at a 90 degree angle there should be a lot of corrections you should do before you get in to inverted flight that need to be learned. If you want to learn that get a SIM its cheaper to
This is what I think Let me know your questions I will try to address them according to my research of the Gyrobot 900
Soon As I can find a good person to hold the camera I will post a video.
