[NSRCA-discussion] Futaba 9z with Spektrum SPMMSFUT7

Fri Sep 7 07:27:16 AKDT 2007

I have been using the SPEKTRUM modules in my 2 JR 10x's for several 
months now.  While the installation with the cable coming out the back 
of the module looked kludgy to me at first, in practice, it has been 
very reliable.  With the 10x, you take the transmitter antenna off 
everytime you put it in the case anyway, so the only additional step is 
the connector on the back of the module.  The only issue I had was the 
outer nut that holds the connector in place on the module coming loose. 
  A drop of CA to keep it from loosening fixed that with no further 
problems.

You will note that none of the add on modules use the existing 
transmission path that go the the orignal antenna. The original path 
would be very lossy to the 2.4GHz band.  The shielded cable that 
Spektrum uses, and the built in antenna on the Futaba modules takes 
care of this.

Several people have tried my 10x with the SPEKTRUM module in their 
trays, and none have been an issue so far.  The transmitter handle is 
already in the area anyway, and the trays allow for clearance for that 
anyway.

Ron, I stand corrected (by my elder) :) .
But that means I then have little respect for the Spectrum 
engineers-because
that is what they have created.
Has changed my mind on getting something they create!!--Too bad I was 
going
to order one from you.
