REFLECTOR: Nose Gear Damper System

As always C-clamp is extra :-)

We debated making the system one style for FG or RG however due to you
wanting the damper inside of the wheel pant on a FG we needed to use
different brackets.  I will try to get photos of the FG setup also.  

I did fly the aircraft and taxi the RG version today.  No issues so the
system is ready to go.  Let me know if you have any questions.

Dumb question.  Why is the system any different for FG vs RG?
