Yesterday I took one of 2 Flysky sets from the back shed and after after charging 12 nimh batteries I bound my first rx and plugged 2 servos in  and powered up to a pair of chattering servos so I searched the web for this model apparently this model Rx sometimes comes dud from factory so I tried the 7 other Rx's all 8 had the same chattering and 20 only shook no other movement so I dragged out the 3ch that uses the same Rx's all had same fault.
Then I pulled the Tx & Rx from a model to test the servos they chattered as well the brain kicks in and I start checking batteries.
One cell in the Rx pack completely dead & the charger was not showing a problem when I took them off charge yesterday.

Two days wasted chasing the problem hopefully I'll remember if it happens again. Embarassed  Embarassed  Embarassed  Twisted Evil  Twisted Evil  Twisted Evil  Twisted Evil

Sorry to hear of your problem.  I assume you have separate 1.2 volt batteries ?

You might like to go them individually with a meter and check their volts.  You might be able save some of them.  You do have a meter, don't you ?

When analyzing electrical faults you have to trace it analytically.  That is to say,  if you change a suspect part with another and the fault persists, then it's likely not that part. The fault must be somewhere else.

Hope this helps

It's getting closer Barrie, I still have to make travel boxes for both models  yet although I have measured them both and sketched what I need
