[NSRCA-discussion] Need header for OS 140

[Dave Michael]

Does anyone have a header for an OS 140 that they want to sell?  Mine broke this weekend and I am just getting going on a new to me pattern plane to fly in a contest later this month (it was a used flexible type).

Pipe is an Aeroslave-  20mm inlet, I believe.  Not sure of the drop- quite frankly I'm not sure how it is measured-  I assume it's the drop measured from center of exhaust to center of pipe.  Any directions/assistance would be appreciated.

Thanks,

Dave
