Airspeed Indicator

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. WhTags:

Turbo compressor indicator

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.

Fuel Quantity Gauges

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

Rudder Pressure Gauge conversion

Radio Altimeters

Lufthansa had Collins Radio Altimeters installed on their B707 fleet (both A and B version). These are the most commons found on early jets built in the US. I found these in U/S condition on ebay and thus they were the perfect candidate for the simulator conversion. This Radio Altimeter
