I have attached a screenshot of BetaFlight, how can I even out my sticks? Is this done in BetaFlight or within the transmitter? I tried resetting the accelerometer via BetaFlight and with the controller. It worked a little bit when I did the calibration with the controller but when I put in another battery, it was drifting again. The drone drifts to the right and yaws a tad to the left. 

I’m using Jumper T lite and Flywoo Cinerace20.

Thanks in advance.

You wont have this problem if you fly acro mode.

You can calibrate the accelerometer in flight using Betaflight stick commands.

Watch this video:



Just not everytime you even change lipo position a bit the calibration will change a ting bit.

I just get this in the ball park range and call it a day.

I’m new and I’m still flying in angle mode. I’ve already tried this calibration from Oscar’s page. It’s not just drifting a little. It’s really noticeable plus my yaw is a little off. How can I set the sticks up evenly? I see in my transmitter the numbers are like what I see in BetaFlight, the problem is I don’t know how to correct it.
I read about the cilli dump but I’m unsure if this is the route I should go, I’m a little timid about changing things without understanding what I am doing.
Thanks for your suggestion though.

If you ran the stick calibration via OpenTX but still see weird ranges in Betaflight then you will need to adjust endpoints in Betaflight using the rxrange commands via the CLI: https://oscarliang.com/adjust-tx-channel-mid-end-point/

Thanks, I’ll try that, I just tried calibrating endpoints with BetaFlight and the transmitter, got everything to read 1500 but it still drifts. I will try the stick calibration via OpenTX again, if that doesn’t work then I’ll dump CLI tomorrow.

Quick question, if I just use acro, the drifts will go away? I never flown acro before.

Thanks for your assistance.

If you fly acro the accelerometer isn't used and you will never be hovering in a single spot, so in acro mode "drifting" doesn't exist. You will always be flying forwards...fast

Hello SnowLeopardFPV,
did you solve the drift problem of your drone ?
I am very interested in this issue because my drone is drifting as well
Thank you

It's wasn't actually me that had an issue with drifting. It was the OP (danny).

Are you flying in ANGLE mode? If you are, these quads don't have position or altitude hold like DJI Camera drones do, so even with the roll / pitch stick left centred the quad is still going to drift due to things like propwash and air movement around the quad in general. Even when flying ANGLE mode, if you want to try and hover in roughly one spot you still need to be giving some constant roll / pitch inputs on the sticks to try and manually keep the quad in position.

Even if you achieve perfect stick calibration on the transmitter AND perfect accelerometer calibration with BF, you will still get some drift in Angle mode. Drift is caused by even tiny wind movements. These little drones do not have GPS (unless you installed one), so they don't have a reference to a spot to hold. They will drift.

Camera drones, such as DJI, have GPS to hold a spot on hover. You don't even have to watch the drone to hover in one spot. A wind gust will come along and the drone will correct its position using its GPS.

So, don't be concerned about drift. These little drones are not for hovering. Never were. You will, as mentioned above, always be flying forward with your cockpit view in your goggles. Enjoy.

Hello everyone,
my drone behaves very curiously when taking off.
In fact, when taking off it quickly tips to one side: it never takes off correctly.
Please watch my short video by clicking on this link:
https://mega.nz/file/KUJUDBjL#SzkNNW5gdy...UgF8gOo-6I

To locate the origin of this fault I removed the propellers and reproduced the takeoff sequence.
I accelerated the throttle as if for a takeoff then I grabbed the drone by tilting it on one side as it does when it is equipped with propellers: the motors correct the tilt of the drone that I cause manually.
This implies that the flight controller functions correctly and corrects the position of the drone in accordance with the orders given by the transmitter.
Question is: why does the correction made without the propellers not occur when the drone is equipped with its propellers at the time of takeoff?
The flight controller is a MATEK F405 V3 card (SpeedyBee F405 V3 Flight Controller)
The motors are A2212/13T 1000KV
The propellers are 1045
The transmitter/receiver assembly is a RadioLink T8FB (8-Channel Remote Controller)
The skeleton of the drone is "X" shaped, made of carbon fiber with a distance of 400mm between each motor
The drone is an X-Quad
All parts are new and have been purchased from quality suppliers.
The programming of the flight controller was carried out by BetaFlight "betaflight-configurator_10.9.0_win64".
The behavior of the drone when taking off is incomprehensible.
I have changed the PID coefficients several times but this has no effect on the behavior of the drone when taking off.
Any help is greatly requested

Double check that your motors are all running in the correct direction. Flipping over on takeoff is frequently because one or more motors are moving in the wrong direction.

Hello FPVme,
of course the first thing I did is to check in depth the 4 motors.
As I wrote in my previous message, I have checked the behavior of the 4 motors after pulling apart their propellers...
I copy below my previous query for you to know exactly what I wrote.
I think that the culprit of such a behavior is lurking somewhere that I didn't identify so far.

Thank you for your help

First thing to do is calibrate the accelerometer in BetaFlight. That will set the level position for Angle mode.

It's a Speedybee V3, which has been the root of much evil and bad characteristics. Some people seem to have luck with them and others can't make things work or fly.

If you have a different FC available (non Speedybee), i'd try swapping it out and see if you have the same issues.

If I was making such a massive and probably expensive quad, I probably wouldn't have skimped on the FC, considering that is the thing that makes it able to fly and I really don't want issues with that part. But the accelerometer is likely the issue. If it is the BMI270 gyro, there are some recommendations for filtering that should be applied, off the top of my head (and no i couldn't find the article on Oscar's site). I have a couple of FC with BMI270 and have just left everything default without issue.

I get drifting on ICM based gyros. Adding caps can clean it up a bit, but not 100%. For 100% stability MPU6000 is where it's at and it seems that's what most people think. Unfortunately the number of available FC with MPU6000 is very small and dwindling.

So based on size, you presumably built this for filming and cine related activities or hauling things. Why are you using Betaflight? iNav has more features that would be useful in something this size. Position hold being a key one.
