Sanwa Super Exzes Throttle Problem

[JCJC]

With Spektrum 2.4 module, was working fine, switched off and 10 minutes later switched on, now no throttle at all, steering still OK. Same problem on three cars.

Have re-bonded but make no difference. Able to bond to a wheel set and all works – so it’s the Exzes or the 2.4 module, my feeling is the handset, have looked for disconnected cables, will try reversing the channels but anybody any experience of testing the throttle pot or anything.

Like the transmitter (oldie but goodie) but feel a replacement coming on.
