Drone in Vicinity of Airport: We were at 400 feet AGL off of Runway 26 in HVR and began reducing the power for normal climb and began our turn toward the southeast. Upon entering the turn; I spotted what was clearly a personal drone (DJI Phantom) off our left wing at 150 feet away and 50 feet lower than our altitude. I alerted the captain about the drone; he made the same assessment about the drone sighting upon seeing it. We then got on the CTAF to let other potential traffic in the area about the drone approximately 1 mile west of the field. HVR UNICOM asked for more details; we gave them the above statement. Upon reaching a higher altitude; we checked in with Salt Lake Center; asked for VFR flight following and gave them the report of the drone sighting.
Pilot reported airborne conflict with a drone approximately 400 feet AGL after takeoff from Havre City-County Airport; Montana.
