fuel soaked rx and servos
 
Gidday, i've done something silly and never checked my fuel lines after a hard landing. My next flight lasted only a minute or two then the engine cut out ( no fuel ). After taking off the wing I see inside the fuse and my lost fuel. My rx and servos were soaked. Will they be damaged ? What am i to do ? The fuel and engine bays are fuel proofed but not the rest. What will happen to the fuse now.? My rx is a JR R700 and the servos are 537s. Any help will be appreciated. John. :(

Had the same situation in my extra with a gasser on it. I took the radio RX and 1 servo apart and sprayed liberally with an electronics cleaner, (blue shower- tuner cleaner or similar)
spray liberally and let dry then put them back together. be mindful of static charges before you handle the RX innards, ground yourself first. If you can find K2R spot remover you can spray that on the soaked wood and let it dry and brush-vaccum it off when dry. Do a search on fuel soak or similar, lot's has been written on it although the tight area's in the back of the fuse may require cutting the bottom open a bit for access

Chances are good that no fuel got into the servos. If it did follow the same practice that I am recommending for your receiver.
Buy a quart of denatured alchohol (not rubbing achohol as that has lots of water in it). fill a small container with the alchohol and then take the case off your receiver. Swish the bare receiver through the alchohol until all the oil is washed off. You may have to refresh the container of alchohol with new a time or two. Now air dry (a hair dryer works well here but you can use your heat gun if you don't let things get to hot). Remember, alcohol is flameable to use due caution. In any event, check the connectors often afterwards as, if you have any moisture on them, they can corrode and cause problems. As an aside, I always drill a 1/4 inch hole in the bottom of the fuselage under the tank to alert me to any fuel leak problems. If it happens, it at least doesn't form a pool inside.
