There are a number of ways to build and several to bond wood to wood or wood to glass, etc. The "old school" method is to use titebond laying out your spars, glueing and adding ribs and pinning as you go. Another option is to use CA glues, laying out and pinning and then come back and glue once everything is straight and plumb. A tight fit between parts is a must when using CA.

A preffered method is usually given in in your plans and building instructions.

The use of titebond or other simular glues will usually result in a heavier finished product and the drying time is signicantly longer.
I always use epoxies anywhere that fuel, castor or oil could reach or contact.
