Title: setting the wing angle
Post by: kingpilot on November 20, 2011, 10:15:04 PM
I bought a Longeze about 3 years ago. I have installed a Dynon FEIS D100, and Dyon EMS10 engine monitor. I have installed a Lycoming 0320 150 HP Engine, removed the 0235. I need some help with setting the correct angle of the wings. They were removed to transport the A/C home. Any ideas ??? ??? Thanks Kevin

Kevin, If you got the builder's log with the plane, there might be some notes in there as to the number of washer that may have been added to obtain the correct wing incidence. Some builders even put notes on the spar as to the number of washer. Can you contact the builder?
Alternatively, did you get the "hot wire templates" for cutting the wing foam, when you purchased the plane? If so, it might be possible to make an upper surface "negative" of the templates, and where you transfer the level line from the template to the "negative". You could then lay the negative on to the upper surface of the wing at the appropriate reference point (Butt line). With the airplane level (top longerons level), the level line on the "negative" should also be level. If not, then you need to add washers appropriately. Make sense??
Another check is to see how well the inboard portion of the wing, mates up to the fuel/baggage strakes.

If you have never flown an Ez before, with new systems and a new engine installation too, I would consider getting an exerienced Ez pilot to test fly it for you.
That way the initial runway flights can determine if there is a serious relative wing incidence rigging problem before committing to flight.
Thus you could start with no washers on the spar /wing bolt joints and use the test flights to get it to fly straight inc rudder rigging.
Mike Melville did a good section on rigging in the CP Notes (#60 pages 11 to 13) inc. an initial 'from the rear' sight test for gross incidence relative differences.

Thank you guys for the info. I can not make contact with the builder (passed away), but I will look at the back news letters and find more info. If anybody has more info/ideas please post. Thanks Kevin

You're getting some good advice above. Where are you located Kevin?

I live in Anaheim, CA. The plane is based at the Corona Airport (AJO) in Southern California. I fly a Beech Bonanza, so I'm still able to get in the air. ;D Thanks Kevin
