<DIV><FONT face=Arial size=2>The forces causing a non-axial roll occur only
during the acceleration phases of the roll ( starting and stopping ).
Undesireable forces are generated because masses at different distances from the
roll axis experience different rates of acceleration. In practice I don't think
we have a problem with the side-mounted engine. Would someone tell me where to
find the Mars pictures.

<DIV><FONT face=Arial size=2>Though on a pattern plane, side mounted is
just point of view. In knife edge an inverted engine is now side mounted.
We're all going to have to go to twins to solve this issue!</FONT></DIV>

<DIV><FONT face=Arial size=2>Looking at the undesirable forces
that would be generated by the assymetric distribution of weight to
achieve lateral balance - hard yaw or tight corners would produce no
effect because all components would be subject to the same acceleration.
There would be an effect during roll, however, because the masses are
subjected to different rates of acceleration (polar ) . Our planes damp
and reach steady state roll rapidly . These unwanted roll forces would
cause a change in pitch ( same as when one aileron has more throw )
during their short life . The magnitude of the pitch change would be
hard to quantify ( by me )
