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.
