Loaded the new MP and .50 and tried useing my JR 12X and R1221 receiver. The R1221 (12channel) wasn't recognized by the ACM. Wouldnt go through the servo setup. The receiver was bound and working well with a servo, but not with the ACM. I tried an older AR9000 Spektrum Rx and it worked fine.
Could there be somthing I need to do diferently?
