Troubleshooting:
zTFRSP's LED does not light up at all
Power is missing.
provide external power from a battery or bec
trainer port and thus power to TFRSP is not activated, see the radio's manual on how to activate it
zChannels are mixed up
It is not a mistake of your TFRSP, but may happen if the student’s and teacher’s radios do have a
different channel allocation scheme.
In case of a JR/Graupner radio (channel scheme 1 Thr, 2 Ail, 3 Ele…) as the teacher’s radio and a
Hitec Optic radio (channel scheme 1 Ail, 2 Thr, 3 Ele…) as the student’s radio, at least throttle and
aileron have to be exchanged. This can be achieved by 2 mixers active only when the teacher is
controlling the model plus 2 mixers active only when the student is controlling the model. Throttle
and Aileron channels should be reachable through mixers only. The example below shows the set
up on a Graupner/JR mx-22, assuming the switch used to pass control to the student is switch 7
In case of a Futaba FX30 and compatible radios (channel scheme 1 Ele, 2 Ail, 3 Thr …) as the
student’s radio, channels 1 and 3 need to be exchanged on the Graupner/JR transmitter as shown
above.
