I finnaly got my build to the point that I can test fly it.
Well I tried, in stabilize mode. I was hoping I will be able to hover just above the ground in my room lol.
It’s bigger quad copter 2000g with 600kv motors and 10" props.
It actuslly looks alright and definitely wants to fly.
Now I know from my experience with helis, its difficult to hold position just above the ground, but is there any mode that will help with that?
I did fly like 1M off the ground, but panicked because it was drifting towards the wall, and trun the throttle all the way down and smashed landing gear (that’s on me)
But I also noticed altidue wasn’t consistent, I was trying slowly lift it up, but it was not going up or trying to go all the way up, almost like i had no control on throttle.
What exactly stabilize mode is trying to do?
Is there any mode to do some kind of tests like this?
Stabilized mode will only level the drone. It won’t stop it from drifting, and it’s still on you to manage the throttle for altitude.
Stabilized is the best mode for the initial flight because it depends on the least number of sensors and systems. Once you know that works you can start using Alt-Hold, Loiter or Pos-hold. And follow the tuning instructions.
Thank you for hints, I will just go outdoors first
Only one more question, is there a way to prevent immidiet throttle cut, while in the air?
I have this stupid habit after micro helis, when something goes wrong I just cut the throttle.
But for this quad it will cut it off and it slams on the ground, when it could just gently land.
Yes practice is the best solution but I am trying to minimize the damage while I am getting there.
Another thing is I can see Copter has so many cool features and options and safety features It’s easy to miss something important.
I am back to 3D printing broken parts and trying again
PS:
I actually can’t find anything, or I am looking it up wrong, but is there any safety switch option, like HOLD in helis, which basically shuts the motors off ?
But in this case is there any way to set it up, so when I turn on switch, it lands immediately (but gracefully) ?
I can see it’s in flight modes, but to flight modes I can only assign 1 channel from what I can see, so the best I can do is 3 flight modes (unless I will do some magic with mixer on my transmitter). Maybe there is easy way to set it up ?
You can setup a switch option to Motor Emergency Stop. RCx_OPTIONS = 31. x for what ever RC channel you want to use. When that channel goes high the motors will stop no mater what’s going on.
I also use arming/disarming on a switch so that will also stop motors in a hurry compared to stick arming.
Thanks for that, I will definitely use it. However I was asking for something like immediate safe landing switch, but looks like it’s only possible via flight modes.
Not as you have described it. There is Land Mode but this works from the AltHold controller and GPS if available. It will not help you flying in your house.
Nice one, I think that’s the one I am looking for. I will definitely go outside, but that will be handy to have that safe land when I “panic”, rather then just cut off motors and smash to the ground
Keep the kill switch or mode switch handy. If you’re just starting your tuning and you have got things set up right there’s always the chance this could go for a moon shot. If that happens go back to stabilized and land it yourself.
There is also a mode called Return To Launch (RTL) that can be assigned to a switch.
When the FC goes into RTL mode the copter will climb to 15 meters and then head towards the place where the motors were armed. The aircraft will hover over the launch point and then land.
For testing purposes I change the value of RTL_ALT from 1500 (1500cm or 15m) to 305cm or about 10 feet.
Well, I went outside, tried stabilize mode, and alt hold
Didn’t go well At this point I am not sure if it’s something wrong with my setup, or still it’s just me.
Basically when I am trying to gently and slowly lift off the ground, it drifts and I can’t really control it well.
I have a feeling that something is not right. I did make sure that motors assignment is A B C D order as it should.
It’s also pretty balanced.
Is it even possible to lift off gently with heavier quad 1500g ? I mean it has to be, otherwise I wouldn’t be able to land safely.
4S Lipo 70C.
I also made sure my flight controller is nicely isolated from vibrations etc, everything seems fine on this side.
Trying to find the correct logs, but I can’t see telemetry logs from my actual flight, only when it was on my desk.
i’ve managed to hover for couple of seconds, 1,5 meter above the ground, but eventually it always starts to drift a lot and I can’t correct ( like it doesn’t listen to radio for a moment ), and I smashes on the fance again
I mean I am not the best pilot, but also not super beginner, I was hoping to at least be able to confidently hover.
