The RT-21 preset potentiometer only has 360 degrees of rotation. Perhaps it
is possible to over-rotate in manual mode if you adjust the soft limits but
I am not sure if the controller will accept this. I recall not being able to
get just a little more than 360 with my TIC's when trying to recalibrate but
I did not spend much time figuring this out.

I have the RT-21 with a Spid RAK and looking through the manual, I am 
almost certain that your G-1000 will be able to do 90 degrees of OT or a 
total of 450 degrees with the GH controller. A quick email or call to GH 
will get you a quick "for sure" answer. Great people to work with and 
fast to respond.
