Has anyone out there tried the DJI E300 Tuned Propulsion system? The ads for it make it sound wonderful with a 20% increase in greater efficiencies. That should translate to longer flight times if it's to be believed. Apparently the kit provides improved motors, props and ESCs. If anyone has looked into it could you please share your findings. I am thinking of purchasing but am a bit worried that the ads are over emphasizing the improvements.
