Servo Tester & Planet T5 Failsafe

Post by Chris Cairns » Mon Apr 27, 2020 10:43 pm

Was having problems with the reverser servo on my Roundhouse Atlantic, so bought one of those cheap servo testers for diagnosis.

The potentiometer on the output shaft is faulty, so fitted a replacement servo.

The Planet T5 radio control system is still very popular in the UK Garden Railway community, but having heard of loco's running away using the Planet T5 system, I was curious to find out how their failsafe system worked. The result is rather interesting.
