<DIV><FONT face=Arial size=2>I'm confused too. I know, I know I shouldn't argue
with someone like chip but I believe the main reason we're putting right thrust
is an asymmetric vertical fin. On most conventional airplanes the area above
thrust line is much greater then area below. So, the spiraling slip stream
will hit the top portion of the vertical fin from the left pushing tail to the
right thus right thrust. When inverted, the spiraling slip stream will hit
vertical fin from the right because fin is now on the opposite side
and pushes tail to the left. To straighten the flight path, we need now
the left thrust which is already there. During inverted push ups, why do we need
to use left rudder? The spiraling slip stream misses completely vertical fin and
the right (left when inverted) thrust is causing airplane to yaw left. If you
have a big gasser, turn on smoke, do inverted push up and watch where the smoke
goes. However, Chip's approach of fixing the inverted push ups problem is
quite interesting and I'll try it on my new bird I'm working on right
now.</FONT></DIV>

<DIV><FONT face=Arial size=2>Cameron Smith relayed comments from Chip ( from
RCU ) relating to how he uses a mix to eliminate the need for right thrust. I
know Chip knows but he left me confused. Could someone clarify what he
said?</FONT></DIV>
