I just saw that for Mavic.
Any plans for Spark? It may improve stability and flight time.

DJI?

if the improve flight time, i'd buy them for sure.

Or even lower the noise levels a bit

All of the above would be fine!

of course it would have better flight time.

If not DJI i have hope there will be aftermarket, maybe also for phantoms.

just a mavic thing for now, would be dumb for dji to not provide extra efficiency to other drones..

We don't receive any news about this. Thanks for your attention to our new release. Hope we will also optimize all series if possible.
