Hello, all -

I've had my 6A for a while, but have not been successful determining what the aircraft can safely do - or not do, aerobatically. Without a 'chute, I don't want to be up there, experimenting.

Can anyone with experience advise:

1. Am I correct in assuming snaps are ok, as to airframe stress? What might be the best entry speed? I'm guessing around 90 to 110 mph.

2. I gather Vans has suggested rather firmly that we not engage in recreational spins. Why not? Do some of you spin, anyway? What is the risk factor? Aren't just two or three turns ok?

3. What about hammerheads? If the a/c allows them, safely, what are the control movements? With my previous military trainer, it was full pwr, straight up to just below stall, then full right rudder and simultaneous full left aileron, followed by immediate full-forward stick, maintaining the left bias. The trainer would then slowly pitch over, do a gentle half-roll, and proceed straight down. I'm kind of missing that!

4. Is a tailslide (as in "a failed hammerhead") dangerous for the 6A - - over-stressing?

    I'm getting a tad bored with rolls and loops. Any sage advice would be appreciated.

            thanks - Mark

Without a chute, you shouldn't be doing any munuvers with a bank angle greater than 60 degrees
by faa regs.

But dosen't she do a great roll.

Well, that's constructive!

"Munuvers?" How about maneuvers??

Back to your cave, laddie!

Mark,

Lots of stuff about that in the archives. Don't listen to me, check there

I have done snap rolls but they are a little a little sketchy because the entry speed window is rather narrow, closer to 75-80 kts as I recall. Work it out by doing accelerated stalls. Make sure your entry speed is less than the speed for a 4G accelerated stall, preferably even slower. It is a supper fun maneuver, but I snapped a rudder chain and also tweaked my rudder doing them, so I have not done any in a while.

I also do multi turn spins (even 10 or more turns). I loose oil pressure at around 8 turns (because the lateral forces build up and empty the oil sump). Also supper fun and relatively benign, at least in my plane. I think Vans recommends avioiding them because you never know if one aircraft will behave differently than the next. Also, it is only a matter of time until someone makes an error and burns in.

I don't do hammer heads because I never got training in them and it just seems to me that a backslide would be very hard on the rudder.

JMHO,
