| Subject: | 3 bladed conversion |
--> Commander-List message posted by: "Jim Addington" <jtaddington@charter.net>
In the class I took years ago on props the instructor said a one blade prop
was the most efficient with two next, three next etc. For you young guys
there was a one blade prop on an early cub.

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.

Who knows or has the Easy Taxi STC on their Commander? Understand it uses a
hydraulic priority value to control fluid to the brakes. STC is for Skydrol
system. Anyone know of a 5606 fluid system.
Thanks and a Good 2005 to everyone!

Ken,
This STC is available for 5606 Hydraulic Commanders. 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.

Ken,
I presume this is to eliminate the "Commander Dance"??. When you don't fly
that often, "smooth" taxing is "challenging". If there is one for a piston
Commander I would certainly like to know.
Years back, here, new pilots got to taxi all around the the field with the
rudder locked by the (external) gust lock in place, I never liked the idea
much, but it didn't seem to do any obvious harm.
Cheers,
Bill Hamilton.

As a new Shrike owner (6 mo.) recently I mistakenly taxi'd with the
rudder lock in place and didn't do the "Commander dance". 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.

Personal opinion only, but one of the things that I have noticed sets us
Commander pilots apart from the rest is the mastery of the steering valve.
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.
