REFLECTOR: Stick Force

[Joe Ewen]

Hi Ken,
Any info on the new pitch trim design would be greatly appreciated.

Also, at one point in time there was discussion about problems with some of 
the nose gear tubes.  Is there any documentation that I can use to determine 
if the nose gear I have is affected.  My kit is DMO 333, circa 1995.
Thanks,
Joe
