[NSRCA-discussion] 14MZ springs

[John Pavlick]

Me too. I have them on my 9Z, 12Z, 12Fg and I had them on my 9C. I sold the 9C and it's still working fine. Futaba does have "heavy duty" springs for the 12Z and 14Mz but they're different than the ones that go in a 9C. Maybe that's what someone was trying to say about using heavy duty springs in a 14Mz. DON'T use the "regular" heavy duty Futaba springs, you have to order the ones specifically made for the 14Mz and 12Z. I think they just want you to use the correct heavy duty springs. Like I said, the Radio South springs seem to work fine and when I had my 12Z in for service a few weeks ago, they replaced the original encoders (my Tx had the original blue encoders) and left the Radio South springs in (they knew they were R.S. springs because I told them so on my work request). They said nothing about the springs causing a problem with the sticks or encoders.

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.
