Title: Vari Eze aileron weights
Post by: Mickeyt9 on November 30, 2011, 11:46:12 AM

I know this subject has been talked about in the past, but I just cannot find the numbers. Does anyone know what the maximum Vari-Eze aileron weight is, and what the allowable difference is between the left and right ailerons?

Thanks, Mike

Mike,

As constructed (per the Aileron Addendum to the VEZ first edition plans, or per the VEZ second edition plans), the VEZ ailerons do not have a weight value indicated.  Weight is what it is, by virtue of design.  As-built, the ailerons must balance at least with the plans-defined waterline of the aileron level, with a trailing-edge-up condition even better.  The ailerons must not balance trailing-edge-low (i.e. aileron waterline low on the aft end). 

The ailerons can be of different weights, but must balance correctly (neither aileron can be TE-low).  Ideally, as close to matching weight and balance angle is the best configuration.  Do not fall in to a false belief that one "light" aileron with a good TE up balance will counteract an opposite aileron that is not balanced correctly.

The big question here is, if you did not build your Eze, do you have all the plans and Canard Pushers?  If not, you need to acquire that data.  For a one-off plans-built airplane, that data is essential to have.

Joe,

I have the plans, addendum's, all the CP's, and most of the CSA newsletters. But I thought someone had mentioned before a max weight. So, before I check my ailerons off as complete I was double checking to make sure I did not miss anything. As far as balance they are within limits per plans. They are 1.5 deg TE up before paint, with a 4.5 oz difference between the two (that was one of my concerns).
The plane was built to about 40 percent by someone else before I took over. I have completed, repaired, and modified the rest. Just needs rigging, and a few minor things addressed to be complete.

Thanks for the feed back.

Yup.  Bill and Lynn Butters' spread of component weights.  Pretty good "benchmark" data for a light VariEze, especially one with an O-235.
