After a few more flights testing heat ,i nmade a heat shield for the nose gear bungee

here is the picjust a simple piece of .016 sheet flanged on the ends and bolted on the the gear channel

 

I also made a simple 2 " lower lip on the cowling

That one I made out of .025

 

i flew it to see the results

now the ambient was lower that the last test but I had much lower OIL and CHTs

but most important was the bungee never go high then ten degrees above ambient !!

now Im going to move the temp probe around a bite and see the temps but after the flight I touched the bungee and just felt around for temp , the bungee was not hot anyhwere and the heat shield was . It clearly was doing the job

 

Now I know the lower lip and the hose helped but even if you do not put a hose on to the bungee at least the heat shield helps

How are you going to inspect the bungee cord with the heat shield in place?
