I see no need for 5 minute epoxy. It's handy for repairs sometimes, but for building there's nothing that needs epoxy that the 5 minute is good enough for.

IMHO, you should get the kit, tools, radio, battery, and servos, and let him get at it. Let him choose his covering colors later. Let him decide if he wants to go glow power or electric. Glow is cheaper and lets a person fly more in a day, while electric is more convenient and doesn't have as big a learning curve.
