googled, and anyone else, plugging hole at the rear of the rx with hot glue will do a lot to keep water out. Also, if you swam the plane out of the pool with the motors the extra drag could mess them up. I woould put the plane somewhere warm and dry and let it sit for a couple of days. I had one that went into the fountain(24" dia.) twice, through the slip and slide jets a couple of times, and finally flew/slid into the pool at the end of the slip and slide. It was bitter for a while, but after a couple of days it came back. That canned air might help clean it out. If you have a compressor I recommend NOT using it. Compressors make wet air.

Neurotex I am building a 2 battery/4 motor mono. I will be interested in whether the rx can support it. Here are pics. It was done I thought when I took these. I was wrong. The motor wires fell off. Now I don't know if I ruined the card trying to solder the leads back on.
