That is why I'm using 700fw on both googles and mavic. The latest one that can be used without phone.

Someone sells my design: Lens holders for DJI Googles by obelix662000

700-700-700. Mavic-rc-goggles. Last fw when no phone needed to fly with goggles.

Imagine you move some heavy brick with hummer impacts and compare it with gentle push with hand. In other words, less acceleration with each current pulse produces less noise, because energy of sharp acceleration is partly goes to sound, not to the rotor movement. From spectral point of view...

You are wrong in both cases. 1. Human ear is logarithmic, 60% reduction means almost nothing on log scale. Read here, there is a test you can check yourself 2. Sine-wave ESCs are switch-on/switch-off. Sine wave is emulated with Pulse Width Modulation. Otherwise power dissipation on the...

Nope, I'm correct For sound level 6dB for double, 4dB for 1.6 times. See e.g. here: Sound level distance damping decibel dB damping calculation calculator change distance versus sound level apps reduction drop dissipation SPL sound transmission loss free field loss sound and distance -...

Unfortunately not. Human ear is logarithmic. To have feeling of 2 times noise reduction the number should be 20dB, not 4. 4dB reduction corresponds to 1.6 times increase of distance from the noise source.

Disagree, sine-wave controllers are still PWM, so no hardware change required. 4dB noise improvement is not actually much. It corresponds to noise reduction with 1.6 times range increase. Will you feel the difference if you stay away 10 m (y) compared to 16 meters (yards)? On the other hand new...

Sorry, my mistake. It works! Many thanks.

thanks, but not working for me.

I can easily enter both HT modes, but how can I exit them? "Reset motion control" does not help, head movements still control the gimbal. HT modes make landing difficult, currently I'm switching my goggles off before landing.

Here is how to estimate time of flight for any type of copter. The Great Copter’s Theorem usage examples
