Took the P4 out for a quick test flight today, super quick to set up and get going - in the air in a few minutes tops. The case made it nice and light and easy to just take out for a quick run.
Nice and stable, very responsive according to healthydrones and my observations.
Also gave it a spin in sport mode, very fast indeed and a lot of fun very impressed with that!
More to come when I test the other features, just gotta wait for the assistant software.

Very Happy though!

Check the firmware, download the firmware in the app, connect the USB cable and OTG to the aircraft and start the update. Keep the remote controller powering on during this process.  After aircraft update, restart the aircraft, connect the app to the remote controller using USB cable and download the latest remote firmware and upgrade the remote.
