I believe the twitchyness of the ME-109 is mainly due to the wheels being so close to the center line. My first tail-dragger was a Midwest fun scale ME-109. Boy, that thing was a beast to take off! As you advanced the throttle, it would suddenly LEAP to the left! I eventually learned to give it a hard bump of right rudder just at the correct moment. Since then I have flown lots of warbirds, but none are as bad as that Messerschmidt!
