[NSRCA-discussion] Plettenberg 30-10 evo and Jeti ESC

Robert,

The only way I can think of that this is a receiver problem is that motor or ESC 
noise is being picked up on the ESC lines (any or all) and the 8 channel Rx is 
somehow more tolerant of the noise or better able to filter it than the other 
Rx.  I would be uncomfortable at leaving this at - I have to use my old 
receiver.   


Ed

Wait a minute. "The problem was with the receiver." doesn't quite cut it.  What 
was the problem?  

I'm glad you got the problem "solved", but you can't trust that receiver until 
you identify the problem.  BTW, "I don't know" is a perfectly valid answer, but 
you could save somebody else a lot of grief if you know what was wrong with the 
receiver.
