Hey,

I recently crashed my I1 V2.0 to freshwater.
Crashed into water - reviving the craft - need HELP

I was able to disassemble the craft, and retrieve the servo. It was a *****. I managed to destroy 3 out of 4 screws.
Where can I find them?

Arms can be moved by the small flat head screw on the bottom of the craft, so mechanically its ok.

PCB does not come out easily. It has been soldered 3 times to the motor, DO NOT try to pry it out..

While the craft turns on, nothing happens with the servo when i toggle the switch or send the command from the app. I guess the stepper motor driver fried.

I am intended to fix it. And I need your help. Yes I saw used complete worm drives for 250 usd, but rather go with the electrical repair.

Where would you start?
