Indeed, looks like the A3 Super II that you have has no pots. I've been using the Hobby Eagle A3 Gyro / Stability System in some of my smaller planes... it does have a master pot, in addition to how you program the unit electronically through your transmitter, the pot is like a physical "master" gain. The A3 Super II, the one you are using, looks nice and as you say it has no pots. A pretty good deal and looks like a nice unit for under $50!

As far as the A3 Eagle Gyro goes, I did fly one plane with both a iGyro 3e and then the A3 Eagle Gyro- it was an FMS 57" P-51. I felt the iGyro 3e was much smoother in feel. This is not to say I did not like the A3. And a lot of this may in fact be due to the fact I was able to fine tune my iGyro in ways I could not on the A3. Perhaps the A3 Super II could meet the feel I had attained with the iGyro 3e, flying the FMS 57" P-51. The options and control available on the Super II looks really interesting.

I've got a Cortex in a turbine, three iGyro 3e's in giant scale prop planes and a high power composite EDF, and a couple Hobby Eagle A3's in smaller planes. Every one of these units does what I expect them to do and I do not feel the desire to take any out! I've even got a Flex Innovations/Potenza Aura 8 gyro in another 3d plane. I like that one as well but it operates slightly differently than the other ones as far a setup goes. Very powerful computer interface, if not a little complicated. Very good performance and feel though.
