Have you been able to observe the physical position of the elevator in flight? What are the symptoms that indicate you need more nose UP trim? (i.e. are you running out of UP authority on the elevator in cruise? Then there's definitely a problem -- but is it an elevator problem or a trim problem or a balance problem?... Or are you running out of UP trim at slow speed? In which case 'how slow?' -- you don't really want to be able to trim much below approach speed anyways). What is the physical location (angle) of the elevator in cruise? What is the physical location (angle) of the trim? How does this 'in cruise' trim point compare to the range you have available on the tab, and it's fullup vs. fulldown position?

Especially on a gravel driveway! Even if you are in a garage, just wet the floor before you paint and you won't stir up any dust while walking around to paint. You can even wet the walls if you want to really eliminate dust. Also, try to manage your hose prior to painting. Dragging a hose across wet paint will ruin your day.

I want to be able to fly the plane only with trim if necessary (ie. If a cable breaks). I'm finding I still need more nose up trim when the tab is max'd out in downward deflection.

In flight I set the tab to have balanced control for straight and level at normal cruise, and left it there until landing. Post landing inspection shows the tab substantially deflected down (not quite max but close). > Have you double checked the aircraft Weight and balance envelope? W&B is inside the envelope, pretty much in the middle. I believe the .5-.8 degree loft on the hstab is the main contributing factor. The change to the attach point is pretty easy really, just need to move the rear holes up 3.7mm. This will involve elongating the holes. I'll then use a stainless washer with a bent tab (kindof like on a bicycle wheel) to keep the bolt in position. Should be no need for a doubler. ________________________________ Message 11 ____________________________________ Time: 12:12:29 PM PST US From: "Dave Alberti" Subject: Zenith-List: 912S installation --> Zenith-List message posted by: "Dave Alberti" Blank -----Original Message----- From: Dave Alberti [mailto:daberti@execpc.com] Subject: 912S Dave, I ordered the firewall forward package with my 912S from Zenith.

I ordered the firewall forward package with my 912S from Zenith.  It came complete with the airbox and exhaust system. I think they also included some fuel line and some T connectors.  The fuel connection described in the manual is only used on the certificated version of the engine and has totally different connections to the carbs.  I ran my lines from the gascolator to a auxiliary electric pump then to the rotax pump then a filter and finally a T to split to the individual carbs.  They were all push on barb type connectors with hose clamps.  One other thing, If you made the throttle to the plans it wont clear the 912S airbox. I extended mine about 2 inches to provide the clearance and it seems to work fine but I only have 4 hours (surgery on my foot is keeping me from flying).  I can send you all kinds of photos if you like, but they are large files and will be slow to down load.

Good luck proceeding
