I have recently obtained a number of Ferranti FH14 horizons. These feature a coloured display with blue representing the sky, and black for ground. They really are superb, and I have used one for a number of years in my Kestrel 19 for some serious cloud flying. When new they cost the RAF £20000, (yes twenty thousand pounds!) but I am selling them with a new inverter for £380. This is cheaper than the other company which sells them, and you get proper connectors for this price, not crappy screw terminals on the inverter.
The horizon features electrical fast erect, power fail flag together with roll graduations at 10,20,30,60 and 90 degrees. The display also has pitch graduations every 5 degress. The horizon has full 360 degree movement in roll and upto 80 degrees in pitch before toppling occurs. Should toppling occur due to reaching this extreme pitch angle, the fast erect mechanism can be used to quickly re-erect the gyro.
Each instrument is supplied with a new inverter housed in a diecast box together with screw locking connectors for all power leads.
