Having recently flown a C152 and having trained almost exclusively in the Tommie i have the opposite opinion of the trim? I found the trim to be in effective on the 152 needing large amounts of movement to effect any change. where as the tommie can be 'flown' with the trim tab. accidently wind on a bit more pitch than is usual on take off and watch that nose come up real fast, ask me how i know!
