[NSRCA-discussion] Arming Plug/Receptacle Problem

[Ron Van Putte]

I did have enough altitude to try a low throttle motor reset to no  
avail.  I couldn't even get it to come up after the airplane was on  
the ground; that arming plug/receptacle is really buggered up  
(technical term I can explain if necessary).
