Stu:
The ICOM has a 9 frequency memory with optional remote switches for both
channel select and flip-flop functions ... essentially the same remote
features as used on the King KY 97A/197A and optionally implemented on
Robbie cyclics. Let me know if you want the manuals and I'll try to dig out
the links.

The one quirk of the XCOM unit in the install manual that I read was that
in order to use the remote channel select / flip-flop features, you lose the
co-pilot PTT button. Not normally a big deal, but could be troublesome if
you're in new airspace with a passenger who is familiar with the area and
willing to do the radio work for you. Also not very convenient for training
purposes.

Can you toggle thru more than just one frequency in the ICOM? I'm flying
a
Baby Belle and don't take my hand off the cyclic unless it is on the
ground
and the blade speed is down. I find that flying around a restricted area
I
can use about 5 frequencies. My Microair is capable of up to 25
frequencies
toggled from the cyclic joystick, but I've had a lot of reliability issues
and may have to change.
