Build Update 1

Page content

This is a short, photo-heavy update showing the build progress so far.

OpenRocket produced some very helpful 1:1 scale PDF exports that made sizing the fins straightforward. The centring rings were also included in the export, but I opted to buy those pre-cut from Black Cat Rocketry.

Marking the fin tab interface

To mark the fin tab interface accurately but simply, I sketched the motor mount geometry in LibreCAD and printed it as a physical template.

Recovery system (initial concept)

An initial concept for the recovery system and anchoring arrangement — this may well change as the build progresses.

With the fins painted, that’s the end of progress for this update.
