Mornin' everybody,
I'm contemplating building a fast (Faster??) RV7 and hope for a 215 MPH cruise at 75% using a 180 HP engine. Where would you guys ,George, start with a clean sheet? My thoughts are:
1. James type cowl and plenum.
2. Rounded lower exit ramp.
3. Gap seals on tail feathers and ailerons (why not?)
4. Fair fuel drains, aileron hinges, etc.
5 Keep weight below 1100 lbs.
6. Has to be side-by-side.....wifey says.
If Dave Anders can get 265 MPH out of an RV4, is 215-220 not reasonable with a 180? What else could improve the cruise speeds?![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
