<BLOCKQUOTE class=cite cite="" type="cite">For many years, the common
explanation for right thrust was torque, and many people still believe that.
This is a case of misdiagnosis. If it is properly diagnosed, a real fix is
much more likely to happen, but doing so with variable thrust is not, IMHO,
the best way to fix it. It can be fixed aerodynamically, but then you run
into the "but it doesn't look cool" syndrome.</FONT></BLOCKQUOTE><X-SIGSEP>
