FIXED!!!! (I never use smileys, but here it is appropriate!) Both John C and Tabb sent me the info I needed to fix it. I had been using the beta tester modules with the beta firmware. For that setup, I had the module mounted underneath the roll axis bar, and that worked great. But the mounting of the modules changed for the firmware in the units available for sale. So when I updated to the new firmware, I should've moved the mounting position to that which is shown in the manual. Per their advice, I moved the module to the roll axis wheel and that did the trick with this new firmware that requires different mounting from the original beta tester firmware. Despite this snag, which probably would've been averted had I studied the new manual a bit closer, I'm a strong believer in the Radian system. It just works. The software is easy to use. And the system is reliable, which is very critical when you're standing there with a client over your shoulder. It has allowed us to pull off moves like you see in our recent test flight below.
