Volador VX3.5 Build flight test w/1404 Motors,Caddx Walnut

Test flight beginning:
6:20 Analog sub250g flight with no action camera
11:45 Test flight with Caddx Walnut

Update: I found the culprit for the spinning anomalies: when i was first setting up the flight controller,5.5% minimum throttle seemed to spin the props really agressively compared to my old build so i set it to 3%. this caused the propellers to stall on zero throttle in counterwind and air mode tried to correct this but didn't have enough time to spin up the propellers,but still sent the signal resulting in the rest of the props spinning up and spinning the whole drone into crash. i set it back to 6 percent minimum throttle and tried to cause the same incident on porpuse but couldn't even push the drone out of stability. Now it flies like a dream.

Testing my new build,still have some problems where i suddenly start spinning sometimes when i go upside down,but i'm confident it's just a gyro/accelerometer problem and i can sort it out in betaflight.Other than the problems that are irrelevant to the build,it flies amazing.
