In-Reply-To: Mime-version: 1.0 Content-type: text/plain; charset="US-ASCII" Content-transfer-encoding: 7bit Wow Jeff, you did a full stop, quiet the engine, feathered the prop and let it glide.....well I admire your guts. But the glide ratio you showing is really awesome, this is much better than even the Evolution has. And this with a piston? So I assume you have a final speed of 120kts? Or do I see this wrong? (because I was also told that if you go to slow the descent rate of the IV-p increases dramatically !
