Extremely light, high impact plastic tubing with aluminum rings resist damage. Available "Aircraft Specific Scales" Can be downloaded and printed from the website.

We will generate an "Aircraft Specific Scale" from your calibration It's shipping tube doubles as a "Vented Storage Tube". This allows any remaining fuel to evaporate between uses, provides a protection for the life of the unit and reduces manufacturing waste. It's design gives consistent readings even when the fuel in the tank is sloshing around. It's upper and lower rings aide in handling. Large Easy-to-Read numbers observed outside the tank. Quantities given in both Gallons and Pounds! Color coded sections represent approx. 1/3 cruise consumption. It's not limited to your aircraft.

Q: Why is this sold as RV specific if it has to be calibrated? All RV models are the same (ie all RV-8 tailwheel). How is it better than a marked rod I make myself? Not to mention I would need to cross-reference a document for the actual fuel quantities. What am I missing?

These do not need to be calibrated, they are pre calibrated for the specific aircraft when ordered. You can change the scale out in these though to use them with different aircraft, those scales would need to be calibrated.

Q: Is there a metric version calibrated litres?

No there is not.
