ORIGINAL: Go-n-up
1. ''I bought a trainer cord'' trust this is a genuine Hitec One Way Trainer cord
2. Both transmitters must have own battery pack. Even though the Laser looks like an older model, it is computerised internally
Alan, the trainer cord is Hitec One-Way (master-slave).
Also, one of the links you provided states that a Laser works as slave with the battery removed.
Years ago, I had a trainer cord and two Laser 4 transmitters. Everything worked great with the master powered up and the slave switched off.
Now, I have one Flash 5, one Laser 4 and a recently purchased Hitec trainer cord. I
thought (assumed, again) that the Flash 5 computer radio would have to be the master and the Laser 4 as slave.
It didn't work with the Laser 4 powered off or with it powered on with crystal removed.
Both ways, there is some kind of interaction between the radios that screws up the Flash 5's signal.
Nothing on the model will respond, either to the slave, or to the master until I unplug the trainer cord.
That's why I questioned if there is something wrong with this particular trainer cord's wiring
(or, maybe the wiring to the jack on one of the radios?), or if there is some incompatibility between a Flash 5 and Laser 4.
Have Flash 5SX but missing a Laser 4/6 from my present collection to recheck now, but from my earlier tests:
.
Hitec Buddy - Trainer Box Compatibility & Battery requirements.
extract:
"Flash 4 or 5 to Flash will not buddy without battery in slave and in some combinations, the slave TX must also be turned on
- always remove xtal from slave in these instances."
Have just revamped my earlier schematics for both the new three part trainer cable pack #58320 and the One Way Cable #58310, as attached.
These will enable you to use a multi meter to verify your cable is correct.
If problems stil exist, suggest remove rear case of each transmitter then check the wiring at rear of sockets has not been crimped/broken when
case closed or any individual socket is not loose and pushing back when plug is inserted leading to a poor if any connection. Refer additional .jpg
showing libe pin voltages - always remove battery and cycle switch, to kill any power retained in caps, before opening Tx.
