Today I took delivery of the Boeing 707 cockpit I have been dreaming of for many many years. This former Saudi Arabian Airlines 707 (HZ-ACI) will become Lufthansa’s B707 D-ABUD/UF (N88ZL) with all panels, most gauges and other parts coming from these two aircraft. My father did his entire 707
After a long search I was able to locate 3 original Lufthansa Bendix Radio Magnetic Indicators used on Boeing 707s! Still missing one but will definitely find that one too.
Vertical Speed Indicator – plain an simple. Original drums and gears removed and replaced with a NEMA stepper motor and a IR sensor for initialization. NEMA is running at 1/16 steps for super smooth and quick needle movements. Stay tuned for upcoming videos of the gauge conversion.
Kollsman Airspeed Indicator
This Airspeed indicator actually came from a B727-100 but since they are identical to the ones installed on Lufthansa 707s I chose this one and painted the 410 kts and 420 kts marker black. Both needles are working on this gauge. Wh

Turbo Compressor RPM indicator
Simple and quick conversion. About 4 hours total time for designing, milling and built. Uses X27 dashboard stepper motor using its internal stop for position reference.
Trim Indicator
This indicator does not need to be converted. This comes from MSN 19521 Air France F-BLCG (my mother was a flight attendant on AF 707s!) that ended its life in Bratislava after a write off. It was repainted in grey but is otherwise untouched. It
Fuel Quantity Gauge 6x
The fuel quantity gauges on the 707 are a bit tricky to convert to stepper motors since the have two needles very close together. The main indicator needle turns less than 315° (which is the limit of the Juken X27 motor) and thus does not require
