Unless you're planning to eat the thing, keep the rice away from it. Rice can not get into places where the water can and already has gotten to, and you're likely to end up with it stuck in places you don't want it.
That thing should have been torn down completely and everything rinsed thoroughly with deionized water and then 100% alcohol. Alcohol absorbs water, as well as those both get into every place that the initial water did as they are also liquids and not something that's best served with some meat an veggies.
You could have a fragged ESC from the crash or from it being in the water, as anything that impairs the prop from spinning properly puts more load on the ESC and can fry them.
If the battery wasn't punctured then it could still be alright, though it needs the same treatment as the rest of the thing and the contacts in the connector should be cleaned. Even then that pack should be watched closely for any future corrosion at the connector as it could corrode at the crimp joints inside the connector where it can't be seen, and a very close watch kept on how it charges/discharges.
I totally disagree. Plus, I said it should be taken apart. Alcohol doesn't dissolve water, it has a high rate of evaporation.
The whole point WAS for rice to get where the water was. Rice absorbs water. It is the standard method of removing water in electrical devices.
I do happen to have a degree in Electronic Engineering. Plus, the rice is removed after it does its job. I didn't say that, but I thought it would be obvious. Every single drenched electronic device on the job and off the job, I have completely recovered it with this method. Decassient powder is better, but most don't have it available.
