Angle of incidence question? - Long EZ Build

I'm almost done with my Raidentech Long EZ build. All I have left is to glue the wings to the wing roots and affix the decals.

In the very limited instructions it is stated that you MUST get the angle of incidence for each wing to match. Any suggestions on the best method for achieving this?

Prop up the fuselage and use two identical spirit levels placed at the same exact location on each wing,shimmed as needed.Double check with a Robart Incidence Meter,if available.

Gotime242, thanks for the compliment! I hope if flys half as good as it looks.

Art, thanks for the info, I have a level, I don't have the Robart meter. Is there any quick and dirty method that's not reliant on equipment I probably don't have

Carshed Again , I'm going to use a HET-RC - Typhoon EDF 4W . I've been told this motor is similar to a mega 16/15/4 in amp draw and power. It'll be turning an APC 7x4 prop and I'll be using a Thunder Power 3 cell 2100 prolite pack. With this setup I'm pulling 25 amps at full throttle when the model is held so I figure in the air that'll come down a bit. It does want to pull out of my hand so I'm thinking I won't be short on power. Do you have experience with this model?

...Happy New Year!!

Ralph,the plastic spirit levels that I use are about a dollar each at a hardware store.They have a hook on the top of each end that lets them hang from a tightly stretched string.The end caps are hexagon in shape,which allows them to rest flat on a slightly curved surface.
Andy Lennon's book on 'R/C Model AIRPLANE DESIGN' has a chapter on CANARD AND TANDEM WING DESIGN that is very informative.HTH. art

I took some measurments and used my levels and in the end eyeballed the distance between the canard and main wing to make sure it all lined up equally.

If you look at the pic below what I did was stand in front of the plane and look directly down the nose, I then eyeballed the distances in the circled area and made sure they were equal...same way I line up the horizontal stab to the main wing on a regular plane.
