REFLECTOR: Main Gear Brake Heat Sheild

[Scott Derrick]

I did the same thing to create a brake tube conduit in the leg, cut 3
inch pieces of plastic straw with a little slit on one end so it would
fit into the next piece. glued them in place, then glassed over them.
Looks good.  I wish I had used straws a bit larger as its a real chore
getting the nylo-flow through the leg conduit.  Takes lots of lubricate
a cussing.

Where the nylo-flow  leaves the conduit there is 4 inches of bare
tubing  to cross to the  brake caliper.  I split some fuel line and
wrapped it around the nylo-flow for rock and heat protection.

I glued a small piece of heat reflector onto the gear leg  opposite 
the  brake disk.  Its  a sandwich of self stick adhesive, fiberfrax or
some high heat fabric,  aluminum foil.  I've never had any problems
before with 450 hours of flying but what the heck.
