[NSRCA-discussion] Fwd: Futaba 9z with Spektrum SPMMSFUT7

[AtwoodDon at aol.com]

The Futaba module system has a small button on the back of the TX module  you 
depress while you are doing the range check.  It lowers the output  signal so 
you can test the range easily.  I think other 2.4G systems use  similar 
techniques.

I can't post to the list from work because I just access my personal  Email 
through the remote access server. You can forward my message if you  like.

Hey, how do you range check a 2.4GHz system since you can't put the  antenna 
down? Do they have a low power mode or something like that?

The  Futaba 9Z transmitter antenna is actually pretty easy to remove.   
However, unless you know what you are doing (think Tony Stillman  here), it can be 
a $%#@! problem getting it back in.  


Re the 2.4 GHz crash:  Some people are capable of breaking  an anvil.

Hey, good point. As you know, removing the antenna from a  9z is anything but 
fun. I've been waiting for the TM-14 module  for my 12Z. The antenna unscrews 
and stores right in the  case.
 
I think it's funny that someone would go to these lengths  (cobbed up install 
of a Spektrum moduel in a 9Z) to try and improve  "reliability" . Is that 
what is really going to happen? All  that cobbery has got to outweigh any 
"advantage" of using 2.4GHz. As  a matter of fact I saw a plane with 2.4GHz stuff 
(Spektrum) crash a  few weeks ago due to - you guessed it - radio problems. I'm 
not sure  of the exact cause but since I know the owner my guess would be  
either an improperly installed antenna or weak Rx batteries.  The plane went in at 
full throttle because he didn't set the fail  safe up correctly either. Some 
people just don't get it...

I  assume that you must remove the 72 MHz antenna from the  transmitter 
in order to have the Futaba TM-7 module function  at its best. True?

Where are the TM-7 module and R607FS  receiver available? Tower still 
says availability in "early  September".
