Here`s my Mk3 field box. It`s getting on for 20 years old now and got repainted about 5 years ago. I went to great lengths to produce the lightest self-contained one I could dream up. It is also 3/16" plywood and self-contained. Hold 2 litres of fuel at one end and Tx hooks to the other for carrying. A 12 volt gel-cell is on the CG in the middle hidden under the power panel.

Tools etc are bare minimum for the flight line or pits and include Sullivan starter in a compartment. I carry a separate small commercial plastic toolbox with lesser required gear in the car where it is available if needed.

I hope it shows up in the attached pic. The two models are O/D sport aerobatic jobs - both getting on for 5 years old and still going. Both are similar design - large one 80" span has OS 1.08 - smaller one 48" span with OS 25 FX.
