I uploaded version 2.5.5 in Mission Planner (I erased eeprom before upload), then went to set up for radio. Before even turning on my Tx for calibration, the bar for the Yaw showed a midpoint of about 1650. Then I turned on my TX (all trims are centered on radio and endpoints are set at -100 +100) and pushed the yaw stick all the way left and right. The low came out to be 1257 and the high 1865. With these numbers, I won't be able to arm my motors. Is this a problem with the new 2.5.5 version? How do I get the yaw setting to be 1500 in the middle with the low to be 1100 and the high to be 1900. Please advise.
