Three of us in our club bought RDS 8000 transmitters when 2.4 radios first came out. All three have experienced the same wire failure though only one failure resulted in the loss of an airplane. I repaired these three transmitters using more flexible wires in a different configuration and I doubt these will fail again. There was quite adequate strain relief in the original configuration so that wasn't a problem with our transmitters.

For the record, the original problem was the result of using wiring that had limited flexibility configured with too short of a loop / cable to allow for the required flexibility.

Most stick assemblies regardless of mfgr. use a similar wiring configuration to what Airtronics uses. Airtronics just had poor implementation of the wiring in this case combined with a poor selection of the wire they used for the application. With a proper repair, there is no reason to fear the problem repeating.
