GLUE, ZAP AND BVM AEROPOXY

Using high quality adhesives such as the ZAP products from Pacer Technology will help protect the
investment made in this model. Through experience BVM has found these adhesives to be the best
available to modelers, therefore they are referred to in this manual. Low quality glues deteriorate with
time and could render the model unsafe.
For extremely high stress areas, such as the wing and tail mounting former to fuselage joints, BVM
has made available a thixotropic, slow cure, aerospace grade, 2-part epoxy system that has been
dubbed "AeroPoxy." It is the strongest and best gripping adhesive we have found. Always squeeze a
small amount from the nozzle into waste bin when first starting to apply the glue or if the nozzle has not
been used for more than a few minutes.

GLUING TECHNIQUES

Except for bare balsa and plywood, scuff all mating surfaces to be joined with #80 grit paper. This
gives "tooth" for the glue to form a mechanical bond. If paint is on the surface, sand through it. If fuel or
grease are on the surface, first clean with acetone or thinner, then scuff. Clean off all excess glue - no
globs or puddles - excess glue is excess weight.
For laser-cut plywood parts, use #80 grit paper to scuff the burned edges of these parts
before applying glue.
AeroPoxy is best applied using an auto mix nozzle. Most applications can be accomplished with the
3-inch nozzle. Small, no nozzle hand mixes can be used where appropriate.
Once applied to a bulkhead-to-fuselage joint, use a finger or cotton Q-tip to make a neat smooth fillet,
while removing any excess glue. Puddles of glue add weight and do not contribute to strength.
Always check the outside skin of the model to look for any glue residue and remove it with Acetone
before it cures. AeroPoxy is tough to remove once it has thoroughly cured.
