REFLECTOR: Fw: Fw: AeroTec Nose gear door retract cylinder

[johnward]

Scott,
    Additional information regarding your msg. of 12/09/04 about nose gear
cylinder leak.  Also check pg. 5, Builder Hints & Information, Velocity
Views#39.  Information about not allowing the slide guides to control the
piston movement and the possible requirement of using a limiting bushing
similar to what is used on the nose and main gear retract cylinders.
