<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>
