Extremely light, high impact plastic tubing with aluminum rings resist damage. Available "Aircraft Specific Scales" Can be downloaded and printed from the website. Can easily be calibrated to any tank using the "Universal" scale. A worksheet, written instructions and even an instructional video are available at 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. Works in tractors, small motors, etc. Will not fall into fuel tank on most aircraft.

One slick product, but requires a little careful work to get it ready to use. Fuelstik provides scales for a lot of aircraft, which you can print out and insert. I found a scale for the 182M Im now flying whose tanks apparently fit a 182P. Printing it out revealed that my printer wasnt true to scale. A little finagling and I got it. Make sure to set aside 20 minutes or so to get this right. But its worth it. Then at the aircraft, remove the cap, and boom: fuel quantity and weight. Plain as day. An elegant design, a thing of beauty.

I printed the scale for my model and inserted as per instructions. No guessing, this thing is very clear and easy to read. The storage container is a great idea no mess and no smell. I would recommend this product.

The issue I dont like about this gage is that the tank has to have enough fuel in it to cause the float to rise. On my RV9a I tried two gages. The universal fuel hawk gage and this gage. The Universal is a simple straw type gage and will record even 1/4 of fuel in the tank. This gage would not give any readings until I had almost 10 gallons in my 18 gallon tank. The other simple straw type gage gave readings at under 6 gallons. So I find the straw type gage better.

Q: Are the calibrated fuel sticks for total fuel or usable fuel? The Cessna 172 I fly has 19 gallons usable out of 21.5 gallons total. Do I order the 19 or 21.5 gallon stick?

The size listed is usable fuel tank size. You would order the 19 gallon stick.

Q: Are the Fuel Stiks calibrated in US gallons or Imperial gallons? I have a Cessna 182Q aircraft, and it has 92 gallons capacity (46 in each tank), but your table for 182Q models only shows 37 gallons. Thanks, Harry

They are calibrated in US gallons. They measure in useable fuel. So 37 gallons would be your useable fuel per tank.

Q: I have an RV-6, tail wheel model. Are your aircraft specific Fuel Stiks calibrated for tail up or tail down? I appreciate that I can calibrate it myself!

Part # 05-12360 for the RV6A would be calibrated for tail up. If you need one for tail down, you would calibrate it yourself with the universal Fuel Stik, part # 05-12361.

Q: I have a prototype aircraft (low wing nosewheel) with 57ltr wing tanks. I assume that the 05-12361 and 05-12362 can be calibrated by myself but what is the difference?

The difference between the two is that Part # 05-12362 uses an Aircraft specific scale and that the instructions are different between the two Fuel Stiks.
