Crashed Drone, Water Damage

Evening,

Earlier on today I crashed my Karma into a tree which resulted in the props breaking and the drone falling into a stream. The drone was submerged in around 2ft of water for around 15 seconds before I retrieved it. I have removed all broken propellers, GoPro Camera seems okay.

ive removed the battery and tried to dry everything off as best as I can by using cloth and a hair dryer.

im assuming there will be some unseeable water damage, although I am going to give it a few days before I try to turn the drone back on, I was hoping you could give me some insight into what I could do or how much it’d cost me for you guys to look at it and repair and damages?

kins Regards.

Ash
