My dad blagged a twin stick 104 ride while he was on a Sqn exchange. The GAF pilot gave him control at the start of the take off roll. Dad rotated when told and they bored upwards at an impressive rate and told him to level off at a certain altitude. Dad missed that level by an considerable margin and the Luftwaffe ace took over with a comment to the effect the 104 must be a lot more sensitive to handle than the Buccaneer.
"I wouldn't know" dad replied. "I'm a navigator!"
