I just had a look at the pics and agree its perhaps a bit difficult to make out how it fits together. So I'll try and describe it. Please remember my A/C is a 601HDS, I don't have any drawings of the XL but I assume its similar. 1. The servo fits in a tray between a doubler and the rear spar immediately behind the pilots seat. This is seen in the second last picture. 2. The control rod from the servo heads towards the centre of the A/C and its bolted to the steel piece that is welded to the end of the torque tube for the aileron cable attachment. It is bolted between the aileron connection (above the aileron pick-up) and the actual torque tube proper. This is shown in the fourth and fifth last pictures. The steel piece I am talking about is painted black. There is no connection onto the actual aileron cables, only the torque tube. There is absolutely no slop in the system. -- Regards, John Livsey ________________________________ Message 2 _____________________________________ Time: 06:02:31 AM PST US From: David Downey Subject: Re: Zenith-List: zodiac metal type ....2024T3 that is!

I've been wondering why this hasn't happened in the past. I'm sort of surprised that the Enigma didn't get there first with it's everything in one approach. I'm a software engineer by profession and I've been thinking it would be fun to write an AP, but I'm completely clueless about hardware interfaces. No time while building anyway.

The Thorp T-18 and the Volksplane II both used antiservo tabs on the pitch control. I have a set of VPII drawings somewhere but the tab is strictly anti-servo and not combined trim and atni-servo. I believe that the T-18 was coupled. The basic concept for coupling is that the sati servo is geared diagonally by a horn from one face of the tab to the reference base on the other face of the stabilizer of fuselage such that when the elevator/stabilator moves nose down/trailing edge up, the tab is driven even further tin the same direction of deflection thus providing a counter force attempting to drive the control surface back towards zero deflection. To add trim tp this concept, the fixed reference base for the tab pushrod is made movable so the the centering bias is affected. Sabrina wrote: Can you find me a design photo of an anti-servo tab like you are talking about (for an XL with a fixed horizontal stabilizer and an elevator where a single tab cannot be placed across the entire surface due to interference by the rudder as in the Zenith)? (You would need to cross-tie the two tabs, no?) Per the PILOTS HANDBOOK of Aeronautical Knowledge 2003, an antiservo tab moves in the same direction as the trailing edge of the stabilator. The antiservo tab also functions as a trim tab to relieve control pressures and helps maintain the stabilator in the desired position. There are computer modeling simulations for that application, but not for what you are dreaming up, as far as I can find. Sorry I cannot help you there...

From: "Sabrina" You know CATIA V5R18 does amazing things, you should try it. I had all the time in the world the last 6 days (spring break) and NOW you want me to do it when things get busy... :o Maybe sometime in June.... First gusty take offs and landings today for the Sabrina Mark 1... finally got the Garmin to talk to the Dynon (firmware update)... and finally got the P lead fed Dynon RPM to stabilize at idle. (200+ K in resistance versus the 30K supplied by Dynon) (flown by test pilot/new owner, not me yet) You guys are going to be credited with helping me come the August 2008 EAA Sport Aviation issue (the credit I gave you in the March 2008 issue, page 91, did not make it past the cutting room floor, so to speak.) (I did mention you guys on the PBS video.) N5886Q is the airplane you all helped build. Thanks again for everything... remember, there is no way Zenith would let a 12 year old kid start building their aircraft and continue supporting her if they thought the sky was falling in around them... CH would let his grandkids fly in the Sabrina, I am told. That alone should calm many fears about the wing design. (I reminded the IA who rebuilt my C150's engine that I was going to take my friend, his daughter, up in the airplane one day, that is the best insurance one could ask for.)
