I use the Multiplex, and would strongly recommend jetpilots to take this brand a closer look, if you are looking for a new radio.

The 4000 version has 12 channels, and anything is possible whith anything, in a easily understood meny.
I know Multiplex is not of the biggest brands in the US, but they are coming faster than some other brands would like..

I use the older version 3030, but this is still moore than enough for moore than most advanced jets today.
Multiplex was the first to launch the digital servo, wich seems to be a must today on vital parts to control your jet.
It also was the first to launch a free programmable transmitter, wich is the basic choice for a jet jockey nowadays.

But many pilots purchase the JR, without first scanned the options of the rest.
I have never had a glitch on my radio in flight, and it has a tremendous range.
300 feet with the antenna short, is no problem (35 Mhz)
I almost lost my big F-15 because of flying to far away, but the radio, was still online. One option on the 4000, is a channel scanner, wich will not allow you to transmit, if your channel is taken.
Of course a free choice, but most of all, the advantage is the menu....
As they say, just my opinion..

Regards.
