problems with 2 x 2.4g sets

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.             

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

Yes Ken I have several multimeters and it was one separate some are getting a bit old I charged about 50 cells 5 wouldn't accept a charge that's why I was surprised when this one died

Hi Damien - sorry to hear about the problems, but I hope this means that two paddle boats will soon be getting the bottoms wet

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
