Could it be a "UR" mode problem similar to "HRS" mode on futaba? Is there a setting for the response time in the KO? I have been considering a KO radio but would like to know if it will give problems like this.
@fastbaja5b; how do you like the KO compaired to the Spektrum?
I just spent a bunch of time trying to calibrate my new MMM to a Ko Propo EX-5 UR, with a KR-407S receiver. My MMM was on firmware V1.22. I flashed it back to V1.21 and I was able to calibrate it. However, it calibrates fine with my Airtronics radio, regardless of the firmware version. It's definitely something that the MMM does not like about the Ko Propo radio.
