Narrative:

Acting as repairman (a&P); tasked to move aircraft from hangar to shop by taxiing. Unfamiliar with the pitts S-2B; surveyed the controls for location and operation. Proceeded to start aircraft; mixture rich; throttle full; fuel pump on check for fuel flow. Mistake starting with throttle still full forward; aircraft started full power. Admittedly I knew I had a problem; couldn't quite get my hand on the throttle and the aircraft was moving toward the hangar. I stopped fumbling for throttle and went for what I could control; flight controls; stick and rudder. Within seconds went from a&P to pilot; the aircraft was airborne. The only problem I had no experience in flying high performance aerobatic aircraft. Took a few moments to become accustomed to the control inputs of this aircraft. I landed the aircraft on the second attempt; the first was a mess. Lesson learned stop being relaxed; and [be] more careful; and use that checklist even for taxiing.
