Here is a small video of the real first flight without problem.

https://m.youtube.com/watch?v=AV0K7whEyVQ

 I tried the GPS mode that works rather well and back in atti as I get closer to the drone.

noted that there was still some wind (10 knots) at the time of the flight.

we also see the foot of of the front arms that vibrate a lot, it's probably due to the printed propellers.

on the other hand I am very disappointed with the autonomy. I have a battery 3s of 2200 mah 45c and I can fly 5min max. the drone weighs 830gr all inclusive.

the battery may have been damaged due to the construction phases due to recharging / discharging ...

I load it with a skyrc e4 so balanced.

Thank you mkc2 for the links!

I will order the slowfy turnigy.

good ... I was able to fly the drone and it flies really well! very stable I am super happy!

I took a risk by printing propellers.

I found these propellers:

 at first I thought I was going to print them just to try to fix the oscillation problem by keeping the drone a little to prevent it from breaking.

finally the drone looked super stable and I took the descision to fly it with the propellers printed. To my surprise it worked!

I would not fly more with these props even if it works well but because I do not think it's very safe but I was surprised at the result.

I would try to put you a video of the real first flight soon.

thank you for your advice, I will continue to tweak the settings

They look ok, if you use those adaptor washers just make sure to clean the little plastic tab off.
What size shaft do you have on your motors.

thanks for the reply mkc2 !

The propellers are 8045 emax nylon bought on ebay, they are fixed (see photo).
On the first flight I had set the gain high enough and by lowering it seemed better. but it still vibrated a lot ... maybe it's my propellers that are not adapted.

otherwise I replaced the broken leg and redo all the welds and everything looks good.
now waiting for new props , and and your advice on the props
