Hi, so when I flew my super cub today, i accidentally went nose down on the lake. It was windy too so maybe that's why but anyways i dont know if my esc is broken or not. Both the servos work but i dont get response from throttle. Im guesssing it got kind of wet but I pulled it as fast I can when it landed and it was floating in the water, so it got damaged. My question is can I still fix this? just the throttle is not working but everything else is good

DO NOT put power into it until the ESC+RX has sat in a warm place (computer top, modem top, etc) for a couple of days, preferably with some air circulation.
Then try it again. If it doesn't work > new one or complete power revamp.
You may have shorted out the throttle side. The servo side is entirely different (BEC=battery eliminator circuit)
Also, blow out the motor and oil the bearings.
If it was salt water...you are screwed.
Look up Corrosion-X if you insist on flying floats.

Wow, and it was only a week old  . Now I have to buy a new esc. You think i can call the company and theyll replace it if i pay like extra because i really dont want to buy a whole new one for 50 bucks. And if someone wants to sell their esc for cheap please let me know |

Flying is not a forgiving sport. You crash, you generally pay.
You can try what you want with Horizon. People have found them pretty accommodating in the past. But....you did break it by yourself. Not Horizon's fault.
I didn't say you HAD to buy one...yet. You do need to dry the other one out thoroughly before trying it again. Depending on how well wrapped it is that can take a few hours to days.
Water shorts out the electrics. You need to turn the throttle off immediately, get the battery out ASAP, and dry things out. Then hope.....
[Seems people never think of this until after they dunk it good]
Note-Water is very dense compared to air. If the prop is in the water and under power it will have huge difficulty turning. In effect it is stalled. This does burn up the ESC (throttle) also, even if the water doesn't short it out. It creates a dead short in the motor. Many people learn that on land with a nose in or crash and not turning the throttle off. Does the same thing. Lesson learned the hard way.
