yep actually all screws in the whole brand new P4 A+ where loose and i had to tighten them all. but i still get alot vibrations. i fly drones for more than 10 years and know you have to balance props out even DJIs.
the stock props are not well balanced from factory. i also tested all other in box propellers and result is same.
i noticed one motor on the left arm is little loose and the plastic frame is squeaking when i move the motor a bit. other arms are better but not perfect so i thought that might be just bad quality.
"yep actually all screws in the whole brand new P4 A+ where loose and i had to tighten them all."
Hope you tightened them to the correct torque, otherwise that may be the problem!
"i noticed one motor on the left arm is little loose and the plastic frame is squeaking when i move the motor a bit. other arms are better but not perfect so i thought that might be just bad quality. "
That's not right, mine are all solid, given a reasonable amount of force.
"now i see these new quick release things and i am not happy about them. i can move all propellers up and down some millimeters. looks normal because the P4 in DJI store is same even i think there should be a better solution. "
They are supposed to move up and down on the springs so that they are quick to release, once in the air they will be held in the up position by the lift which should lock them firmly in place. If they move up and down without pushing on the springs then that is a problem. You do have springs on the prop mounts?
"i am thinking about to get rid of those quick release system and use the other carbon props from my P3 with same propeller adapters as P3 have."
The quick release system has proved itself to be far more reliable than the P3 "self tightening" screw system, almost zero propellers flying off in flight. Also very few people complaining of vibration.
"so thanks for your answer so far. when you think its not normal i want follow your advice and not fly but instead keep an eye on this problem first. i will do a short video soon and post that here so we can all figure out whats the cause and how to prevent it in future. ill keep you updated."
Maybe it is a question of standards, of course the standard props are not perfectly balanced, but however well you get them balanced it is always possible for someone else to be dissatisfied and be able to do better! I guess a video would help to understand what we are talking about...
