Dan,

        Thanks for your input.  I found that both sequence valves in the
main gear wells were plumbed backwards.  The manual states that the inlet
port is connected to the high pressure side and the outlet port goes to the
inboard gear cylinder.  The inboard gear doors  operate properly now.

        I did have some difficulty getting the gear to free fall as well.
They would stick in the gear wells.  A slight push brings them down. This
resistance to fall was also the result of the incorrect plumbing of the
sequence valves.  Now the gear comes rocketing out of the gear wells when I
hit the dump valve.

        I have noticed that the nose gear bangs on the nose gear door and
leaves a mark ( yes, I did plumb the nose gear door sequence valve properly
:-) ) when the nose gear is coming down.  Anyone else have this problem?
