teflon tubing - what type to use?

[jim ivey]

The tubing does take a set.You have to make it conform to the pipe-header 
with heat. I did it in an emergency at the Pensacola contest last year using 
the exhaust from my buddys diesel truck.The teflon came off the ES pipe I 
was using on my 140L.With the ES pipe the tubing has to be enlarged 
slightly. I made a tapered form out of a broom stick for this. Any source of 
heat will work. Use a torch or monocote heat gun and be very careful how 
tight you snug the hose clamp or you will collapse the thin wall tubing of 
the pipe. On the 2 strokes you can use tie wraps to form the tubing with 
heat applied.Then use the ties to secure it to fly. The temp on the 2 
strokes won't melt the ties.However I did slightly collapse the wall on my 
Greves pipe with plastic ties.Be careful.I have reused the teflon.When it is 
cold it will slip off and back on fairly easy.
Now you know all my secrets.
