Friends and others,

LOL!  Others???  :-)

Attached are some pics of the model and the new exhaust. The “NewExhaust2” picture also shows the new intake in the upper right corner.



Performance Re-cap:

                        Static RPM     Flying RPM      Max Speed

Original               4100                 5150(max)       157kts TAS

New Intake          4250                 5400               162kts TAS

New Exhaust       4500                 5950               179kts TAS


The new exhaust looks fantastic, and obviously works well too.  This is really the way these projects progress.  Stage one is just to get it flying, which is tough enough.  Next, you find that you have lots of improvement available in power, and reliability.  You're doing very well Joe, though your last message about my RV-8 engine didn't make sense.  Have you been huffing the epoxy fumes again :-)


Cheers,

Rusty (Giving Tracy no chance of flying before me)
