Rocketman has tried to compare the Multiplex 4000 with
the JR 10 and Futaba 9, but I think the Multiplex is in
a different class. It is far too different to a standard radio.
I have and used one for flying the Rig and can say, it is totally unlike any radio out there...

What basically make it different is the fact you can assign
any stick to any channel to any function. This also has
its drawbacks.

The Profi 4000 is the most difficult to learn but also
the most capable

The question remains, is all this power and capabilities
required to fly a turbine plane. I think the answer is no.
I flew the DC-10 on a Futaba 8 channel and its up to the
user to get what he/she wants and decide how to use the
channels.
