Thanks
He almost never left the ground.
I will remove the cage to protect it and I will redo the accelerometer calibration. I will post a screenshot of apm planner too.
I have redone an accelerometer calibration
it moves on the sides so I can’t make it take off too much …

That’s looking much better. Pitch is near zero and the motor outputs are reasonable. They won’t be equal if one has a different kV than the other 3. You should replace the other 3 but I suppose I would take it outside and hover in Stabilize then try AltHold. Do you have GPS? I can’t tell, that logging option is not enabled.
I don’t have GPS.
Would it be really better with all the same motors ?
Yes, I think it would. I see now you have disabled all arming checks I suppose because of no GPS. You would be better off just disabling the GPS lock check and keeping the others on.
Sir I think it’s not really appreciate because my last experiment is doing and I’m successful on my experiment.
There is 2 green motor is 2300kv and 2 red motor is 2550kv also different props (high pitch also low pitch 【new , old】)
-
1st experiment is stable the quad. With different kv motor (props are same on all motors)
-
2nd experiment is change props and try it and 2nd time succes. (Differents props on all motors)
Happy flying 
I have seen little evidence of good flight characteristics from any craft you have posted about and I would not suggest such a configuration.
Firstly I’m Scarry about 2 is high kv and 2 is low motor and rpm and etc etc … But when I arm my copter then all scarry is outdated and try to stable my copter.
Stablize mode :- Once I rise a throttle then 1 side down my quad (no any tune) but when I’m quickly rise up throttle to 50up percentage its flying no drifting (little bit nearly 20 to 30cm)
althold mode :- work completely but more area to recover stable position (drifting like a 2 meters to recover stable position)
Happy flying 
Will do 
I will try to have the same motors.
Many thanks for your support !
I am amazed that you can keep it in the air with having a different motor on one leg could you not locate another motor that’s the same spec.
How much does the frame weigh compared to the model I bet it cuts down on your flight time.
Good luck finding a motor that’s the same as the one that died and getting it to fly correctly.

Hi
I have just replaced the motor to have all the same.
Have to test outside at the end of the afternoon …
Hope I won’t break anything
Cheers

Breaking things is expected in this hobby.
You are right
I have tried outside but it goes ahead and it lost a propeller just after take off.
