Jack,

Here is an article written George Moffat:

The HP-14 answer to your question is found in the third from last paragraph.

Paul Bikle's T-6 version the HP-14 limited flap deflection to 68 degrees.
In the following article he states that 68 degrees provides a glide ration
of 6 to 1.

This was more like parachuting than flying. Nothing but dirt out the
front of the canopy.

Anyone know what the actual L/D value is with 90 degrees of flaps ??
