[NSRCA-discussion] Futaba 9z with Spektrum SPMMSFUT7

Fri Sep 7 12:22:12 AKDT 2007

I agree that a lot of R/Cers should not consider opening the back of  
a transmitter to do an installation like this, even though most could  
probably do the job if they thoroughly researched what had to be done  
before starting the job.  Sadly, many are unwilling to read  
instructions before jumping into a job.  These people should never  
open the back of a transmitter.

I remember when the first dual rate switches were used on  
transmitters.  Transmitters did not come with them installed.  A  
young guy named Jim Oddino (remember him?) published a how-to-install  
dual rate switches article in his R/C Modeler magazine column back in  
the 1970s.  I read the article thoroughly, bought the parts and  
installed dual rate elevator and aileron switches in my Kraft KP-7Z  
transmitter.  They worked perfectly!  Club members looked at my  
transmitter and I could see the thought going through their heads,  
"If Van Putte can do this, so can I!"  Pretty soon, transmitters all  
around my club were sporting dual rate switches.
