The 14 is in a completely different league than the 4000. Off hand several
features, sythesized, shift selectable. memory card, computer upgradeable,
channel expanders, etc.... Sailplane capability are probably similar except the
14 is 2048 capable and will soon have the 2.4 module and receivers out.
The biggest difference is the ease of programming. I had a 4000 and finally
gave up. Plus I didn't like the tray deal. You can pretty much program a
competition sailplane without the manual. There are only a couple of small
items that fall into the "head scratching" category and they aren't bad.
For those that finally make the step into the 12 or 14 and realize the power
and ease of this system there is no looking back.
Hell, even Bubba got one a dem.

The Profi 4000 has all of the 14MZ functions that count (sorry- no audio)
"plus' several more that most sailplane guys will never use but are there for
the really technical applications.
Not very popular because of the style but it is fantastic if you use a tray
or strap. Programming is really logical and quite easy once you understand it
and is is a lot less expensive than the 14.
Too bad Hitec will not support them much longer but we all hope they will
come out with a radio as complete to replace it someday.
My two have been bullet proof for about six years.

True enough. Unfortunately not enough of the 14MZ radios are being used
in soaring (big in aerobatics and helis) to realize what an incredible
radio it is for soaring. Assign any function to any stick, switch,
slider, etc. Including mixes, trims, whatever. Whatever you can think of
you can do. Same holds true for the less expensive 12Z and 12FG.
Up to 9 flight conditions per model. Each condition allows you to change
EVERYTHING except where the functions are assigned and the channel.
Anything else can be changed. Throws, mixes, etc.
The Futaba 12 to 14 series radios are truly powerful and flexible
radios. Honestly I cannot imagine having to mess with anything less now.
Kind of like once I got a microwave I could not imagine how I got along
without one.!!

True for airplanes. Futaba has been in the car/boat world for sometime
and has pretty god market penetration there.

In a sense I agree. It can become a very academic argument. Personally,
I like the continuous hopping scheme over the other types of implementation.

SS I agree. But radios in general not so much. At many large contest
Airtronics still rules the roost with Futaba and JR splitting the
remainder. Plus it can be very regional as well.

In SS this is true. However, given how tiny these things are I can't see
that as an issue. At least for me. Even the 14 channel RX is smaller
than most 4 channel 72 RXs!!
