Yuneec H520 slow airspeed

[Gert De Wachter]

Hi,
my H 520 no longer reaches its maximum speed.
I can't go faster than 4 m / s.
I have already done a complete reset of the software on my St16. I have performed the calibration of the compass and the accelerometer several times. I have performed the calibration of the RC buttons and a reset of the E90 camera.
Nothing helps.
Can someone help me?

oh my god you are right how stupid.
I've never noticed this before.
Is this a recent change or has it always been that way?

Thank you terrence davidson
