REFLECTOR: Corrosion

[AnnSam]

Flying 11 years, hangered 100yards from salt water, so far no problems found
at annual inspections.

  I haven't seen any discussion on corrosion prevention tips for the
Velocity, so to open it up, here's a few ideas that I've done that might be
helpful:



  1)       Nickel-plated all steel parts. (concentric t.tube, bell cranks,
door HW, etc.)

  2)       Used LPS-Hardcoat for the inside of aileron & elevator torque
tubes. Will use in other areas as I go.

  3)       Using Teflon lubricant/protectant on moving parts (elevator &
aileron hinges, etc.).

  4)       Switch to stainless steel HW wherever possible. The cadmium
plating on screw heads gets scratched off after several assembly/disassembly
cycles. Nothing pretty about rusting screw heads!

  5)       Standard zinc chromate & paint for other aluminum surfaces.



  For those already flying, have you noticed any particular "weak" points
when it comes to corrosion?



  Probably overkill, but I want to fly this one for a long, long time!

  1996 SEFG.
