the Hal works the same way. does the co pilot make you keep the stick over?
butttttttttttttttttt
a instructor can flick his switch when he knows the learner cant save it, the learner is more likely to flick his switch much earlier ( or forget it all together ) also the Co pilot cant throttle up and save a stall.
if the learner is flicking his switch all the time he isnt learning not to get in trouble, and not how to get out of it, most instructors will wait for a while before taking it back.
i fully agree with not leaving a trail of planes ( $$$ ) in your wake as you move up through the stages. IF you prove good enough.

i still dont agree that hi-boy trainer lands easier than the fun-fly, yes it sat there nice and steady, but on landing the wind kept lifting the wing and the slow responce and throws made it very hard to track back on course, i came in with a lot of rudder to help, and i know how to use it, learners dont
most trainers also have a wing loading way too low, making them unstable in wind, and sail past you on landing despite the lowest of idles
