[NSRCA-discussion] RX choices

[Park, Ihncheol]

My only reason not using the PCM is the lock (failsafe).  
Sometimes it gets uglier than FM which goes crazy for a while.  

Very good flying experience when hit while using FM RX.  

Fail Safe is not something that recovers the plane to level, upright.   
I wonder if we can add some kind of device similar to Pilot Assist to make
the plane to roll or pitch itself when the TX signal is lost or RX losses
signal.

If noise is issue, it is good to go with PCM.  (lots of heli guys are using
PCM because of mechanical/electrical noise.

I have a question guys.

I see in lots of posts guys using FM (PPM) RX's.  Why is this?

In today's market there are so many choices of good PCM RX's I can't
understand why someone would actually choose to run FM. Back in the days
when I started RC there was no PCM and we had the choice of AM or FM. I was
taught that my model was too important to me not to run the best link
possible, at the time FM was it.

When PCM came in the price was much higher and I can see a reason to not use
it. Today however both Futaba and JR have PCM RX's that are good for under
$99, JR now even has one that PLL Synth. So why use FM?

It is my understanding with today's PCM that noise rejection is so much
better with PCM that it seems along with its F/S properties both model and
people are better protected. I can see the reasoning among average modeler
its price why else do MPI, FMA and so on make such a profit on off brand
leads and servos that are in my opinion very sub par. I felt that in the
pattern community with available models shrinking, and the cost of models
hitting larger prices that guys would trust their baby to better equipment. 
I mean a basic pattern model that is on the cheap is going to be $1000 to
$1500 all up. The difference in a 127 Futaba RX and say a Futaba 138DP PCM
or JR 790 PCM version is about $40

What am I missing?
