Different courses, different students, no confusion. 160 was used for Army grading and MELIN as I recall, 260 for RAF/NAVY EFT. 260 has a throttle on the left as well so both pilots can have right hand on stick, left on throttle, also should be flown from RHS solo so instrutors are used to flying from either seat.
More confusing was the fact that after 5 minutes in a 160 you were at 3000 feet not 6000
