It is a good idea to send in the receiver. That is depending on what the receiver is worth. The last two in sent in after a swim cost me around $40. It's good piece of mind. Have them put a new antenna on while you are at it and if it is dragging on the runway and catching in the wheel, you would be well served by re-routing it.

Check the plane out carefully. I put my Ruperts in the pond a couple weeks back. It glided in nice and slow and was setting just in the water with the wings clear. I pulled it out by the tail and it weighted a ton. It leaked water out of the wing all the way to the pits. There was one small tear in the covering. I've been toying with the idea of recovering it for awhle and now the need was there. when I tore off the covering, the LE sheeting had been pushed in and broken between ever rib on th left side. Then I noticed a strange tear on the top side and when I pulled the covering off, the leading edge and lower spar were both broken. It's repairable, but it quickly went from a dry out to a major rebuild. I glad I pulled the covering, It was good for one half a loop and in it would have gone. Check things closly after the water landing. THere can be a lot of hidden damage.

you shoudl make sure your servos are OK also. They don't like water any better than the receiver. The power switch might stand replacing also if it was wet. The last thing you want is a intermintent switch. I think that may be what put me into the drink to begin with.
