Bobby,

 

So the only one flying a 13B is = Bill Shertz??

 

The rest of us are flying 26Bs or = 39Bs??

You can roughly calculate the VE of an engine if hp is known = with:

VE =3D 5600 X HP divided by (RPM X Displacement in cubic = inches)

This would indicate that the = rotary, with a VE of 1 would require  a displacement of 160 cu in to get a HP of = 180 at 6300 rpm or 200 at 7000 rpm.

 

So what is the deal on the 1300 = cc?  that is about 80 cu in.  about half what would be required to = produce the HP we hope to get.
