Good if you want to teach kids or those who are shorter in stature, but although your legs reach, aft cyclic gets buried in your tum...
?????
Maybe my tum isn't as big as yours.
Never had that problem.
I've tried a kid's booster seat. It's OK for short flights, not for long ones, and definitely not for instructors flying all day. It's far too solid, and will give you backache. It's also the wrong shape, and slips.
OK, so I'm a sensitive little soul who wants to be comfortable and doesn't mind paying for it. Tease me all you like. It cost me about....20 minutes in an R22, 10 minutes in an R44, a couple of minutes in anything else. Get it in perspective, guys and gals.
