We didn't look at the instructions and therefore assigned throttle cut to the flight mode switch which caused a confliction, I checked the instructions and changed the throttle cut switch from H to A and all was good. the only thing about the assembly I thought was awkward was securing the wing and the velcro supplied to install the batteries, after replacing the velcro to something more appropriate no problems. We will do a maiden flight at the next weekend where there's minimal wind. Overall Caleb enjoyed the experience.
