Jim Addington N444BD -----Original Message----- From: owner-commander-list-server@matronics.com [mailto:owner-commander-list-server@matronics.com]On Behalf Of W J R HAMILTON Subject: Re: Commander-List: 3 bladed conversion --> Commander-List message posted by: W J R HAMILTON Folks, I note the comment about cruise speeds 2 v. 3 blades. Several friend recently upgraded their C-310A. Manufacturers STC etc. The outcome was a disaster, turned out no testing on this model had been done, the vibration on takeoff was frightening. After much investigation, balancing etc., nothing changed. All of a sudden, the manufacturer decided a full refund would be a real good idea, it was an inherent couple that was causing the highly dangerous situation. Also, with a later model C-310, the only discernable performance change was a loss of about 4kt IAS in cruise, which worked out at about AU$7500 per knot, ripper deal. Cheers, Bill Hamilton.

It is pretty much a re-orifice for the brakes, making them less sensitive if we're talking about the same gizmo. I've flown an AC-685 and a few Turbo Commanders with them. It's an Aero Air (Hillsboro, Oregon) STC. Also available for 680-F series piston models. Wing Commander Gordon Life is not simple anywhere. Probably less so elsewhere. ________________________________ Message 5 _____________________________________ Time: 05:04:37 PM PST US From: YOURTCFG@aol.com Subject: Re: Commander-List: Ft.

No harm was done but it trained me to keep the rudder pedals neutral. It's not a bad idea for training eliminating the habit of using rudder input to taxi. -----Original Message----- From: owner-commander-list-server@matronics.com [mailto:owner-commander-list-server@matronics.com] On Behalf Of W J R HAMILTON Subject: Re: Commander-List: Easy Taxi STC --> Commander-List message posted by: W J R HAMILTON Ken, I presume this is to eliminate the "Commander Dance"??.

Why not just spend the required 10-12 hours learning to taxi the airplane well? It's not difficult, just a short but steep learning curve. The Easy Taxi STC seems like a good solution for a nonexistent problem. Again, just my humble opinion. /J ----- Original Message ----- From: "W J R HAMILTON" Subject: Re: Commander-List: Easy Taxi STC > --> Commander-List message posted by: W J R HAMILTON > > Ken, > I presume this is to eliminate the "Commander Dance"??.
