<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>
<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>
