I converted the Lindberg kit to RC back in the late 80s. I used a disassembled servo for the motor/speed control, and fit the batteries under the deck. The only place for the bulky receiver was in the back of a 3/4 ton Dodge Weapons Carrier, hidden under a tarp.
With modern radio gear, it would be much easier to RC the boat and leave the cargo bay empty.
One thing-- the stern of the Lindberg boat doesn't match the drawings in the USNI Book Allied Landing Craft of WW2. That book shows the LCVP with slightly curved transom, while both the Lindberg and Italeri kits have the transom in a shallow V shape. I had always assumed the Lindberg kit was wrong, but now that the Italeri kit is out and has the same shape, I'm not sure what to think......
