A change of plan, rather than have the AA pack mounted 15mm off the floor of the boat, sitting on packing foam, I have put the original battery in a tub with a splash cover over it.
The Rx, a Futaba R114F is also located in its on protective case. though i have not tested the battery tub in anger, the Rx case came in handy last weekend after a good swamping.
her hull is filled with strofoam packing as well
