Oil Temperature Gauge

Oil temperature gauge was heavily corroded and was no longer working forcing us to replace the whole mechanism as new instruments are next to impossible to find.

By removing the complete interior of the instrument we only had the dial, pointer and the housing left. using a standard Hitec HS55 servo we were able to easily build a fully fuctional gauge again. The pointer is glued onto the servo arm and the servo glued to the dial. care must be taken to get the correct distance between the dial and the pointer. It should not exceed 0,8mm.

Controlling a servo is fairly easy with a Opencockpits servo card or arduino card. The main advantage of opencockpits is the relatively easy configuration and connection to the simulator offset.
