Hi!
IMHO, you don't need a lot of equipment. Apart from obvious things such as radio, plane, fuel and a glowplug battery you only a few things are necessary.

Nice things to bring along:

* A small first aid kit (just in case)
* Chicken stick to start your engine
* Spare prop (especially if you are a beginner)
* Spare glow plug
* Glow plug / Prop nut wrench
* Some extra fuel tubing
* Some tape (to repair cuts and bruises in the covering).
I have found that surgical tape sticks to almost anything (buy
at a pharmacy).
* Screwdrivers that fit the screws in your plane (usually 2 is
enough)
* Pliers (a flat nose is most useful)
* Some extra bolts, screws and nuts that fit your plane.

Note that I don't have any glue in my flight box. Any mishaps that involves the glueing of parts and/or require more tools and more spare parts than what I include in my field box are best repaired at home.

Good luck with your new aircraft!
