Some notes from Simon:

• Opencockpit DC Motor Board (interfaced with SIOC)
• Takanawa 555 metal gear DC motor, attached to home made plastic motor carrier bracket
• Lower trim axis rotates six times, multi-turn pot rotates ten times; requires a gear ratio 1.5 or 1.6 (45 vs 30, or 48 vs 30 teeth)
• Original movable joint if motor axis is not exactly aligned
• 1.5 gear ratio for feedback on multi-turn pot
• Foam sound insulation
