Had a few spare minutes this evening while everyone else went out for some last-minute shopping.

You have to make your own arrangements to mount the internal stuff; another indicator that these models are not for the rank beginner.

Due to the Laser's carb location, I need to get the tank as high up in the fuselage as I can. Here's the solution; a simple ply tank floor, to bridge the space in the existing ply sub-structure, with sufficient hard foam padding epoxied in place to give the required height.

The floor is screwed into place with servo screws for easy removal. A velcro tie-down strap is screwed and epoxied in place on the bottom.
