It is a sad fact thet the storage box will always be a bit bigger and take up more room that just the boat on its own.
Several of my smaller boats/landing craft reside in cut about two-ply corrugated card boxes in a manner not dissimilar to DG`s, thick large card boxes can be had from appliance shops (they chuck them out sometimes but I am sure if you asked) or even garden centres.
BUT…the boxes stack on top of each other, they can sit on the floor…they can be put end-ways on higher shelves. I stencil mine with the name of the craft and a little 2.4 or 2.7 next to, to signify the transmitter needed.
How about a box for the GC, so arranged that the end hinges, and so the box can simply be plopped on the floor and the boat wheeled in and out ??
A box saves so much damage and is really very easy to transport. Odd boat-specific spares can be kept with the boat in its box. and so on.
To my mind its a no brainer and not dissimilar to buying a cycle for £1500 and then getting a wire lock for it from halfords for £5
