First build, mass and CG

A side view of the aircraft cut along its centreline, nose to the left, on a pale ground. Inside the grey shell are the dark battery pack, green circuit boards and the fuselage spars; a tall keel hangs below. Thin leader lines run from red dots on the parts to labels above and below, each with a mass in grams. The title gives the design CG at Y 268 mm and the mass as 3.02 kg, with the stall test aim of 266 under it., ivory colourwayA side view of the aircraft cut along its centreline, nose to the left, on a pale ground.

Fuselage C v2.4B, the first build, on keel B with no payload, cut away from port, nose to the left, with the mass of each assembly and the CG marked; the pack's front is at Y 76 on the CG slider. The masses are th-aeronautics' reconciled build-up (tools/cg_c24b.py, with the blank payload cover in ASA at 33 g), about 3,024.8 g for the day build, and they stay estimates until the aircraft is weighed and balanced. The design CG is Y 267.52 mm at the slider's forward stop and 272.44 at the aft stop; the aim is 268, which the pack reaches at a front of Y 75.6, 1.6 mm into the travel, and the stall test aims at 266 on brass washers in the Trim Bracket, flown at 267 or forward (th-blender W127.2).
