Excellent lgmac. I what I do with all my receivers these days is to purchase some Velcro. I buy it in industrial strength bulk but any kind of velcro will work. Cut a strip of the Hooks that will cover most of the back side of the Rx on this strip carefully spead a thin layer of medium Ca. next cut a strip of the Loops that will at least be the size of the rx or even bigger which gives some room to position the Rx later. This strip you carefully sprad a thin layer of medium Ca also and thin place this in the airplane where you want the RX.

The velcro will provide all the vibration isolation needed in addition this method will provide for cooling of the rx. Formally standard advice said to wrap the rx in foam and tuck it in somewhere. With the new 2.4 systems heat seems to be more of a problem and many manufacturer are recommeding to avoid the wrapping we used to do and acted as insulation.

For batterys I do exactly the same and all my batterys have the Hooks portion of Velcro and the airplanes all have the Loops glued inside.
