Bobby,
So the only one flying a 13B is Bill
Shertz??
The rest of us are flying 26Bs or 39Bs??

Elsewhere on this same site he
claims”
You can
roughly calculate the VE of an engine if hp is known with:
VE = 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.

I would highly recommend that any of you
running an IVO in-flight adjustable prop to take a few minutes of your
time and read Ross's write up on his SDS site...some great information found
at:
One thing I found interesting for
instance was his use of a dedicated AMP meter on his IVO circuit
which then allows him to set his pitch based on the amount of amps he
is pulling...
