After updating to the firmware .500 RTH works strangely.
When I press or when it comes back to disconnect ... travel oblique..not traveling straight but slightly across.

DJ Spark broken? To calibrate Compass and IMU? Flash the firmware again?

Helpme tnks guys.

How is your spark flying apart from RTH is it flying straight, is it hovering horizontal, if it is then it's not IMU, was it windy?

Flies straight but as if going in oblique in rth. But dronie example works well (example of automatic command)

If it's flying straight, would wind have caused it, or what height were you RTH at?

It's hard to know maybe give it another try see if there is any change. Upload your log and see if there is anything unusual.

Ok so it auto landed I thought it flew RTH so it looked a bit off when it was descending. It could be Imu , best way to check is start up and raise about 1.5 metre just let it hover and check its holding it horizontal level, keep at this height fly back forward left right just a couple of feet, and see how it is. Do this in windless condition.

However, aircraft is horizontal with the ground ... (today I also saw landing from the palm)
But if it wakes wind, is not it written in the app?

I'll wait for a windy day
but it's hard

just make sure everything ok after update the new firmware, are the RTH still have a bug ? *scared to fly right now
