[NSRCA-discussion] Pipe Length

[Dave Smith]

Thanks Mike.  I ran this prop for a few flights on the same pipe setting as I used for a 16x12.5 wide APC,and 15% Cool Power. It would turn about 7400,but I backed off the needle so that it barely touched 7200.  It pulled a 10.75 lb.
Brio surprisingly well but certainly not well enough on verticals.
My mistake in misnaming the fuel I intend to use.

Thanks again          

Dave

  One more thing, the Cool Power is 20% Problend.

    What would be a good starting point to set an ES tuned pipe,Model 2C 140MU on an OS 140 RX,(w/extra head shim and OS "F" plug),running on Cool Power 20/20?

    Prop is APC 18.1x10.1W.

    Thans,Dave  NSRCA  #943
