<DIV>Actually, I said something a bit incorrect about the blender, as it
eventually does become an autorotation, so it is in a stalled state
eventually. Anyway, if you haven't lost one yet you must be doing
something right! For the most part, if you are
flying 3D, you will bend or break airplanes more frequently
than otherwise.</DIV>

<DIV>Thank you Ed,</DIV>
<DIV>I stand corrected on the blender, now that you describe the entry,
I remember it, can't do it right, but I remember it. I guess when
I'm just out there, slammin' around the sky, I don't realize the real
stress on the airframe. I must be pretty lucky I haven't lost one
to breakage yet, at least in the air.</DIV>

[SPAM] Re: [SPAM] Re: Snao G's</DIV>
<DIV><BR></DIV>
<DIV>Ken:</DIV>
<DIV>Depends on the pilot. Some do Walls at a fairly high
airspeed. I never did them at anything much more then around 40
mph est, but that's a bunch of force right there. It stops in a
big hurry. I can only guess at the G's, but if you watch from
the right angle, you can see the wings bend a fair bit on a 40% model
doing this. Ditto with a Parachute - it just depends on what the pilot
is willing to attempt. Blenders aren't a stalled maneuver, they
develop from a rolling vertical downline, then at 3D rates you
typically slam in full down, full aileron one way, full rudder the
other, then you typically take out some aileron to flatten it
out. I have seen airplanes come completely apart, sometimes just
crack the wing sheeting (sounds like a rifle shot) or crack the
fuselage doing a blender. I never let mine develop for more than
a couple of rolls at a low power setting coming down. Too
risky. </DIV>
<DIV> </DIV>
<DIV>Usually Waterfals are started from a vertical hover and are
really tame. A really wild variation is a Waterfall started from
full power level, with a very rapid pitch-up to about 45 degrees as
you yank the power, then hit full down (3D rates ocourse) and knock
some throttle back in to get enough propwash over the tail to force it
around as it starts to go backwards (same direction really, but the
tail & nose positions are getting swapped). Timed right, it
virtually stops in place as it pivots around the pitch axis.
It's dramatic and you can immediately go into anything else like a 3D
roller, whatever, where a second ago you were clipping along at 90
mph. That's a wing tube bender if you overdo it. There's more
tricks and variations than this, but there is alot of really
stressful stuff in the so-called 3D maneuvers. I like EFD
(Extended Flight Envelope, better, but whatever.</DIV>

<DIV>Walls I can see the stress, however I understand that the
correct way to enter a wall is at 1/4 throttle or less. I'm
not one of those big ego guys, so correct me if I'm wrong.</DIV>
<DIV>Parachutes are more of a controlled fall, from a partial wall
up high, and Blenders begin from a stalled state. Of course
when you slam the throttle to push the plane through the Blender,
that could hurt a bunch.</DIV>

<DIV>Yep, but the transition into it can be stressful. Stuff
like Walls, Parachutes, Blenders, certain brands of Waterfalls put
mucho strain in the airframe. </DIV>

<DIV>Matt,</DIV>
<DIV>I could be wrong, but isn't 3D, by definition, done in a
constant state of stall? Wouldn't that eliminate a lot of
the high G's in the maneuvers? I wouldn't think the
airframe would be in as stressed state, when the flying surface
is depending on prop wash, not air speed, to do it's
thing.</DIV>

<DIV>If this accelerometer is finding 13 G loads
generated by a Pattern model snap, a relatively low
amount really, I imagine that a 3D model set up for a full
array of stunts has to be experiencing double that at
least.</DIV>

<DIV>Earl could you do any 3D type maneuvers and

<DIV>Good point. Once in the stall, the model should not
see the same continued G load. Should drop
dramatically. If the plane doesn't stall to begin
with, different story.</DIV>
