Main Assembly Sequence
- Check for bubble level and other tools in tank.
- Remove stickers on IP and clean with ethanol (some were missed last time).
- Wipe rusty screws on IP LVDTs and surrounding area with ethanol-soaked wipe.
- Check that all in-air cables are labeled.
- Fix broken pico adapter cable?
- If possible, reroute cable to eliminate need for with feedthrough.
- Debug all electronics, especially actuation.
- Check IP yaw.
- Recheck centering of suspension in assembly frame.
