Once you have both sides of the fuselage cut out, prep the inside of both fuse panels.   I use mineral spirits and scotchbrite.  Wet the coro with mineral spirits, and thoroughly scrub with the scotchbrite, then wipe dry with a cotton cloth.  


Double check that your engine will fit the coroplast cutout.


mine ended up a bit small, then i opened it up a bit too much.   No big deal, just mark the centerline of the engine, from front to rear, using the flute as a guide.   This line will become the wing centerline, and the hor. stab centerline.

Next,  from the 1/4x3" piece of poplar, cut out 2 pieces 3 1/2" x 3/4 for engine bearers.  Then cut a piece of 1/4" square poplar dowel to fit the rear vertical portion of the fuselage, and glue in place.

Line the top engine bearer in place, then lay a dowel above it.  Mark this flute from front to rear, to use as a glue line.  




also mark the place where the dowel stops on the engine bearer. Glue the dowel to the bearer, and also do the same for the bottom rail and dowel.  Then glue the top rail in place, and place some books on it to keep it nice and flat until the ca cures.


Once the glue dries, clamp the motor to the top beam, and then push the bottom bearer rail assembly up nice and tight against it.  Line it up with a flute from front to rear, then mark its position.


Once you've got it marked, remove it, and glue it in position.   Put some books back on top until the glue dries.
