On February 20th, I received my brand new P4P. Did 2 test flights to discover the quad and compare to my previous P4 and everything seemed to be working fine.
Then I updated to the last firmware and the nightmare began. After 10 other test flights, I discovered the problem was the VPS detecting ground even when the drone was 50m high.
Leading to RTH problems (quad stopping on its way home and climbing way above RTH height), and unresponsive stick inputs (the quad beeing fooled by the VPS).
Disabling the VPS was a solution but no more precision landing, security, ...
So, mid March I sent it back to the supplier (StudioSport in France) where it stays in its box during almost 3 weeks.
They finally send me a new one which I received this morning.
First thing : unconsistent firmware (for the battery I presume) ! Seriously ? On a brand new quad ?
Then, the quad was on a table and the IMU values were changing from green to yellow then to "moving" !
And finally the gimbal which emits a very special sound and moves almost constantly !
I updated everything and made all the calibrations : IMU, compass (which was in yellow condition), gimbal and RC sticks.
IMU and compass values seem to be fixed, all green (will make a test flight after 6pm due to military airspace active now from SFC to 250ft)
But the gimbal is still making the strange noise and moves.
And the battery has already been charged 6 times (the P4P box seal was not in place) : this probably explains the inconsistent firmware message, the original battery has probably been given to someone else.
Have to say I'm desperate
