<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> </DIV>
<DIV>Earl could you do any 3D type maneuvers and measurements with
the Yak?</DIV>
<DIV> </DIV>
<DIV>Very informative discussion BTW, and may result in improved more
efficient building technique, read-- lightest for the desired
strength.</DIV>
<DIV> </DIV>
<DIV>thanks</DIV>

<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>
