I have an Avistar with a Skysport 4 in it. Last week it had some radio problems while flying. When We inspected it on the ground, (it landed ok, not crashed) we noticed that the fuel tank was leaking. It seemed to saturate the receiver. I took the cover off of the receiver and sprayed circuit board cleaner on it thoroughly two sepaerate times. The servos still chatter when I turn the Tx And Rx on on the bench, right next to each other. Is there anything I can do to better clean the Rx out? Should I send it in for repair to the Futaba guys, or is it a lost cause and needs replaced? Thanks for any help, Tracy.

Tracy,

A fuel-soaked receiver can be permanently-damaged. Even if PC board cleaner is used to degrease it, the other components of the fuel, as well as the oil that's soaked into some of the receiver's components can render the receiver useless.

We'd suggest that the receiver should be replaced.

what happens if you seperate the reciever and transmitter by 10 feet?do they quiet down or still chatter?is the reciver antennae straight and away from any electrical wires including servo wires?

Don't chance it, send it in!

Thanks everyone that responded. I'm making arrangements ot send it in. THanks again, Tracy in Omaha.

Why send it in when the response was to replace it??. I assume Bax wouldn't want to return it "repaired".

The assumption here is that a qualified service rep can determine if it is permanently damaged or not. If this is not the case then I do stand corrected!

Thats a good point 4*. I suppose from what Bax said it would be better to replace it. Thanks for pointing that out. Tracy in Omaha.
