<DIV><FONT face=Arial size=2>Bill,</FONT></DIV>
<DIV><FONT face=Arial size=2> There is
enough "give" in the assembly to allow you to take a 1/16" off the rear
face or the right-hand side to get a bit more side thrust.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The down thrust is controlled by raising the rear
of the structure with a shim where it notches into the former on the u/c support
plates. I have done four of these this way. (The only one that failed was the
one that hit a tree after the battery terminal came away from the
cell!.)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The "box" does not shift position. It is still an
"open box" and the sides are stiff enough to stay pointed forwards.
Capping the top and bottom locks it in place.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Lining up the engine is a bunch of fun. The cowl of
the FOCUS-2 is repositioned so you have to line up the mount and engine in one
go. I'll send you a picture of a tool that I made to do this if it is not
already out in MA.</FONT></DIV>
<DIV> </DIV>
