[NSRCA-discussion] 14MZ springs

[verne at twmi.rr.com]

I've been using the Radio South springs in my 14mz for the last 4 years. My original encoders were replaced by Futaba as a routine factory upgrade when the radio was one-season old but weren't actually causing me any problems. I had sent the radio in to have a defective trim switch replaced and Futaba just routinely upgraded the encoders. The RS springs have worked fine for me.
