Observations... I notice you have not inclined the motor to change the thrust angle. My build of the "Smash Drone", a similar foam board pusher design by Cstence, flew MUCH better after I changed the thrust angle. Before the change - when I applied throttle the plane went 'dead' and was reluctant to climb. After the change - the plane was much more responsive and flew very freely. I'm sure the flight times were better as well.
See my logic in these articles;

(At the end you will see the Smash Drone and how I decided on a new thrust angle.)

(Explanation of changes , plus before and after video showing modifications to design and performance improvements.)
On your plane I would find the TRUE CG and then direct the motor thrust through a point a little above it (1-1.5cm?) - to allow some of the thrust to counter the additional drag force that comes from the wing when the throttle is increased. I think you can change the thrust angle easily with a few washers under the bottom two mounting arms on the motor. JUST a suggestion though :)
Can I ask what your AUW is with the 1300mah & 2600 (2x1300?)mah battery?
Cheers, alibopo.

I know for the thrust angle it's not good...
Thanks for the advice !
But i don't understand : What is the ''AUW'' I don't know this word in english xD ?!

The - AUW - stands for "All Up Weight". What does the plane weigh (grammes) when it is ready for flight with a full payload of batteries, camera and FPV gear?
It would help me compare it to my Smash Drone - 950 gm (with 2000mah LiPo)
Thanks, good flying :)

What place in France is that? I visited France some years ago, but just Paris and Loire (Amboise).....

I'm happy to join your community. This is a great plane so I am wondering if any pdf plans are available.
Sorry if I missed out links that might have been posted in that regard :)
Cheers !
