REFLECTOR:Pitch Trim Spring

[Joe]

Jack,
You may want to consider adding a Dynamic Brake Circuit to the pitch trim.
This should reduce the servo overrun.  A simple DB circuit diagram for the
Velocity's pitch trim can be found in Velocity Views Vol. 6, page 14.  I
have not gotten far enough in the building process to test if this circuit
works, but I am planning on a DB when I get there.
