Narrative:

Initial climbout; given instruction left turn northeast. Pilot flying (sic) observed difficulty in roll and pitch axis. Pilot monitoring (PIC) made positive control exchange and verified the aircraft; hand-flown felt very heavy in the roll control and decided to return to airport of origin. At this point ATC noticed the deviation and queried the crew. PIC decided to [advise ATC of the issue] due to difficulty in maintaining aircraft control and wanted freedom to deviate as necessary to mitigate the situation. Aircraft landed no flap without incident.
