Narrative:

First officer was the flying pilot. After rotation first officer felt the elevator was heavy and oversensitive. After we cleaned up the aircraft and ran the checklist I confirmed that there was a 5 second delay between elevator command and elevator reaction. [I was] asked to return to the airport and notified flight attendant; operations; and passengers that we were returning to land. I did not declare an emergency; approach was normal until flare; then the pitch became over sensitive; notified dispatch and maintenance.

Title: DHC100 flight crew detects strange elevator response during takeoff and initial climb. The crew elects to return to the departure airport where maintenance discovers the autopilot elevator servo is partially jammed. Tail winds during the elevator check prior to takeoff apparently masked the condition.
