Also determine where you will be mounting radio box (and the servo layout needed), fuel tank, exhaust, Air scoops and air flow, floatation (in the hull and under the hatch), transom hardware. Personally I have not got a particular order I use when doing a build. Some things make more sense than others. Realistically the transom hardware and the motor should be installed before other components as they don't have much flexibility on where they should be.

Post some pics of what you are building!
