Disarm not working and too much lift

TheExplorex

I've calibrated my drone, however I'm facing two problems.

Firstly the drone arms itself when the left stick is lowered to bottom right, however as per the manual it doesnt disarm itself when the stick is lowered to bottom right, so there is no way to turn the drone off unless disconnecting battery or waiting for it to completely drain. Is there some setting or code I must edit?

Secondly when the throttle is completely lowered the drone has too much lift and takes off, do I need to edit a setting in QGroundControl to ensure the armed speed is lower than what it is so it doesnt take off when it is first armed?

Thanks for any help.

Are you using a new firmware you just compiled locally?

Suggestions:
1) Please check the airframe type you selected. Different frames have different settings on PWM outputs to motors. Select 'NanoMind' from QGC. the default setting for NanoMind airframe is tuned to make the drone stay on ground unless you punch thrust.
2) That may require you to re-calibrate after selecting a new airframe.

rolandash the settings were right. I recalibrated the remote and that seemed to fix both problems. Disarm now works, except when the drone flashes magenta, it seems to not be able to disarm and I have to let the battery drain.

Good to know it works.

LED flashes magenta usually means remote control lost connection (or too much vibration under some circumstances). Try to avoid antenna been shielded by battery, etc, (or avoid brutal touch down as possible)

rolandash I've realised the when I flip the drone (just learning and trying to calibrate) it freaks out and turns from blue the state where I can disarm to magenta.

I cant disarm in this state. I'm able to adjust the pitch, yaw, roll and throttle so I know its recieving commands however I cant disarm, any workaround?

I am not sure i understand your problem. Is nanomind connected to QGC through a USB cable when you flip the drone? (as you mentioned you are trying to calibrate)

But in that status you should not be able to ARM the drone, as it is in pre-flight stage.

rolandash sorry, I meant calibrate as in the variable dials on the controller. It is not connected to QGC. When it flips with nothing connected it turns magenta and unless I disconnect the battery there is no way to turn off the drone.

Oh OK.

By default NanoMind is in Stabilized mode, means there is an estimator inside flight controller is helping to control drone's attitude and maintain stable. When its flipped it is obviously going beyond the controllable range of the estimator so that's why the drone lost control.

Currently it seems a limit that pilot can disarm the drone at this status. There are probably some settings in QGC that can set a cutting angle - motors will be cut if angle exceeds some value - or will be implemented later soon.

But things are different in Acro mode (purely manual control). You can switch to that mode(using switches on remote controller) and have a try.
