After staying up altogether too late I am getting very close to a complete design of all the profiles that will form the hull shape.

The thing that has been giving me sleepless nights (literally, I think I have a problem letting go of projects) was how to make the "fuselage" removable in order to get to the electronics within. I think I have achieved that now, while maintaining what I hope will be an easy to assemble design.

The "lid" will rest on a 12x12mm stringer of balsa or similar, this prevents it falling in to the cavity. I also made sure that there would be suitable (I hope) edges everywhere where I will be glueing down the "skin" wood.
