It's an eye opener. www.baileycar.com/oil_overview_html.htm Enjoy, if you have the time.

ANSWER Yes indeed there is! Don't ever use automotive oil in your aircraft engine. These oils are now blended for use with unleaded fuels, and the additives in auto oil cause problems in an aircraft engine that operates at much higher temperatures than the automobile engine. We have encountered engines with holes burned in pistons due to the use of automotive oils that have an ash deposit causing preignition. It seems awfully hard to convince people who have had great success with the oil used in their car that it may not be used in their aircraft engine.

You can figure it out pretty easily. 25 degrees would be 12.5 degrees either side of center (that seems awfully small to me so perhaps it is 25 degrees center to full deflection). So you end up with a right triangle with a 12.5 degree apex. Therefore the distance from center to full travel on either side would be given by two times the arctangent of 12.5 degrees times the distance from the hinge axis to the trailing edge of the rudder. total-travel = 2 * (atan(12.5) * distance-to-trailing-edge) Since the trailing edge of the rudder is not parallel to the rotation axis, the distance traveled will depend on where you measure it. Regardless, the above formula will work in all cases if you take the measurement from the hinge to the trailing edge. Be sure you measure perpendicular to the hinge axis.

The new T-shirt at All Red Star this year was going to depict a CJ on the tail of a T-34 and a Yak on the tail of a T-6....."Taking over the skies on T-arget at a time!" Perhaps the graphics will need to be revised to show strafing of the T-34 on the ramp! Barry (screw politically correct!)

A large part of my responsibility is to track who's membership and FAST dues are current. In addition to the improvements that Deon, Drew,AMy and the others added to the web site we changed credit card systems and banks. It is possible that in the changes, some information didn't port over properly. If you suspect an error in your account (usually not showing up to date) or have any other questions, please contact me and I will sort it out. If you need the new member or renewal form, I can send you that too.

Heat lamps are incandescent filaments in a thin glass bulb. One drop of anything on a hot bulb will shatter it. Then the filament burns and if there is anything flamable around (gasoline spings to mind here) then a large conflagration will follow. Something less dangerous would be better. ________________________________ Message 13 ____________________________________ Time: 08:29:48 PM PST US From: "Gus Fraser" Subject: RE: Yak-List: Cold weather starting procedure --> Yak-List message posted by: "Gus Fraser" How about these http://www.1066.net/southernaviaries/brio.htm Gus -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com]On Behalf Of Ron Davis Subject: Re: Yak-List: Cold weather starting procedure --> Yak-List message posted by: "Ron Davis" A heat lamp would heat the engine, but there's a downside.

I guess I could say that was a test to see if anyone was paying attention but the truth is I screwed up in interpreting Note 2 of Fig. 1.4 (Tech. Specifications page 6a) Cheers; Walt ----- Original Message ----- From: "Walt Lannon" Subject: Re: Yak-List: CJ RUDDER TRAVEL > --> Yak-List message posted by: "Walt Lannon" > > Kelly; > > 25 degs. -1/+0 or 257 -11/+0 mm at the trailing edge of rib #3 which is the > centre hinge rib. > > ----- Original Message ----- > From: "Kelley Monroe" > To: "Yak List" > Subject: Yak-List: CJ RUDDER TRAVEL > > > > --> Yak-List message posted by: "Kelley Monroe" > > > > Does any know the rudder travel for a CJ?
