The RC Field Box for use with RC Glow Plug Engines


The ideal RC Field Box is one that carries your model airplane fuel, starter, battery and RC tools and is not too heavy!

It is all too easy to put everything you think you will need, into your field box, and then find it is far too heavy to lug from the car to the flight line!

 The first principal to apply is to keep things simple. A full jug of model airplane fuel and a 12V RC battery are heavy enough, on there own, so keep the compliment of hobby tools to a minimum and leave the heavy duty tools in the workshop!

The box we are looking at today, is the Great Planes Master Caddy. It comes pre-built and finished and all that needs to be done is the basic assembly.

A unique feature of this box is the removable Auxiliary Power Station (APS), This unit can be seen at the far left of the RC field box. It contains the 12V battery, the starter and the power panel.

The advantage of this design, is that the model can be assembled and fuelled, in the pits or at the car and then the APS can be removed from the field box and the engine started at the flight line.



Great Planes Auxiliary Power Unit



I have found this arrangement, very useful at one club that I fly and a real plus at some fly-ins I have attended.

The two drawers can hold a lot of stuff, but remember what I said about weight!

A layer of rubber or thin foam drawer liner can keep things from rattling around too much.

Regarding which tools and things you need to carry, Screwdrivers, both blade an Philips heads and a pair of pin-nose pliers along with a good set of tweezers, is a must. I find that a particular model needs hardware peculiar to it, so I usually have a small pill bottle, with all the nuts and bolts required, along with a few spares, clearly marked and stored in one of the drawers.

A fresh bottle of CA (small) is always useful along with a roll of electrical tape and a spare RC glow plug.
