Glueing is Important
Glueing technique revisited

BVM instructions include a chart (shown below) that suggests what type of glue works best with each specific combination of materials.
Our models rely on the use of quality glues for sure, but the knowledge of which type to use and how much to use is also extremely important.
Turbine power presents new challenges to the structural integrity of our models and therefore the proper glueing techniques are paramount to the ability of the airframe to handle the increase in aerodynamic loads and "G" Forces. So don't skimp on the use of glue, on the other hand, know that puddles of excess glue do nothing to improve strength but do add weight.

Gluing Techniques - this is straight from any BVM instruction manual

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. Epoxy resins that are designed to be mixed in a 50/50 ratio tend to stay soft and gummy if too much hardener is used. When using a filler such as milled fiber or microballoons, always add the filler after the two parts of the resin are mixed. Mixing milled fiber (BVM #1905) with epoxy glue as supplied in the kit helps to strengthen the glue joint. Mixing microballoons with epoxy glue will weaken the joint, but makes a fillet that can be sanded.
For laser-cut parts, lightly scuff the burned edges of these parts before applying glue.

BVM recommends using high quality adhesives like those produced by Pacer i.e. the ZAP products. Cheap glues produce short lived and weaker joints.

The BVM Aeropoxy is best used for very high stress joints where a thixotropic (won't run), slow curing bond is desired. Wing and tail mounting and landing gear mounting systems are examples of very high stress joints.
